Obesity

TOPLINE:

Moderate to vigorous aerobic physical activity performed in the evening is associated with the lowest risk for mortality, cardiovascular disease (CVD), and microvascular disease (MVD) in adults with obesity, including those with type 2 diabetes (T2D).

METHODOLOGY:

• Bouts of moderate to vigorous aerobic physical activity are widely recognized to improve cardiometabolic risk factors, but whether morning, afternoon, or evening timing may lead to greater improvements is unclear.
• Researchers analyzed UK Biobank data of 29,836 participants with obesity (body mass index, › 30; mean age, 62.2 years; 53.2% women), including 2995 also diagnosed with T2D, all enrolled in 2006-2010.
• Aerobic activity was defined as bouts lasting ≥ 3 minutes, and the intensity of activity was classified as light, moderate, or vigorous using accelerometer data collected from participants.
• Participants were stratified into the morning (6 a.m. to < 12 p.m.), afternoon (12 p.m. to < 6 p.m.), and evening (6 p.m. to < 12 a.m.) groups based on when > 50% of their total moderate to vigorous activity occurred, and those with no aerobic bouts were considered the reference group.
• The association between the timing of aerobic physical activity and risk for all-cause mortality, CVD (defined as circulatory, such as hypertension), and MVD (neuropathy, nephropathy, or retinopathy) was evaluated over a median follow-up of 7.9 years.

TAKEAWAY:

• Mortality risk was lowest in the evening moderate to vigorous physical activity group (hazard ratio [HR], 0.39; 95% CI, 0.27-0.55) and even lower in the T2D subgroup (HR, 0.24; 95% CI, 0.08-0.76) than in the reference group.
• Mortality risk was lower in the afternoon (HR, 0.60; 95% CI, 0.51-0.71) and morning (HR, 0.67; 95% CI, 0.56-0.79) activity groups than in the reference group, but this association was weaker than that observed in the evening activity group.
• The evening moderate to vigorous activity group had a lower risk for CVD (HR, 0.64; 95% CI, 0.54-0.75) and MVD (HR, 0.76; 95% CI, 0.63-0.92) than the reference group.
• Among participants with obesity and T2D, moderate to vigorous physical activity in the evening was associated with a lower risk for mortality, CVD, and MVD.

IN PRACTICE:

The authors wrote, “The results of this study emphasize that beyond the total volume of MVPA [moderate to vigorous physical activity], its timing, particularly in the evening, was consistently associated with the lowest risk of mortality relative to other timing windows.”

SOURCE:

The study, led by Angelo Sabag, PhD, Charles Perkins Centre, University of Sydney, Australia, was published online in Diabetes Care.

LIMITATIONS:

Because this was an observational study, the possibility of reverse causation from prodromal disease and unaccounted confounding factors could not have been ruled out. There was a lag of a median of 5.5 years between the UK Biobank baseline, when covariate measurements were taken, and the accelerometry study. Moreover, the response rate of the UK Biobank was low.

DISCLOSURES:

The study was funded by an Australian National Health and Medical Research Council Investigator Grant and the National Heart Foundation of Australia Postdoctoral Fellowship. The authors reported no conflicts of interest.

With all the excitement about GLP-1 agonists, I get many questions from providers about which antiobesity drug they should prescribe. I’ll tell you the methods that I use to determine which drug is best for which patient.

Of course, we want to make sure that we’re treating the right condition. If the patient has type 2 diabetes, we tend to give them medication that is indicated for type 2 diabetes. Many GLP-1 agonists are available in a diabetes version and a chronic weight management or obesity version. If a patient has diabetes and obesity, they can receive either one. If a patient has only diabetes but not obesity, they should be prescribed the diabetes version. For obesity without diabetes, we tend to stick with the drugs that are indicated for chronic weight management.

Let’s go through them.

Exenatide. In chronological order of approval, the first GLP-1 drug that was used for diabetes dates back to exenatide (Bydureon). Bydureon had a partner called Byetta (also exenatide), both of which are still on the market but infrequently used. Some patients reported that these medications were inconvenient because they required twice-daily injections and caused painful injection-site nodules.

Diabetes drugs in more common use include liraglutide (Victoza) for type 2 diabetes. It is a daily injection and has various doses. We always start low and increase with tolerance and desired effect for A1c.

Liraglutide. Victoza has an antiobesity counterpart called Saxenda. The Saxenda pen looks very similar to the Victoza pen. It is a daily GLP-1 agonist for chronic weight management. The SCALE trial demonstrated 8%-12% weight loss with Saxenda.

Those are the daily injections: Victoza for diabetes and Saxenda for weight loss.

Our patients are very excited about the advent of weekly injections for diabetes and weight management. Ozempic is very popular. It is a weekly GLP-1 agonist for type 2 diabetes. Many patients come in asking for Ozempic, and we must make sure that we’re moving them in the right direction depending on their condition.

Semaglutide. Ozempic has a few different doses. It is a weekly injection and has been found to be quite efficacious for treating diabetes. The drug’s weight loss counterpart is called Wegovy, which comes in a different pen. Both forms contain the compound semaglutide. While all of these GLP-1 agonists are indicated to treat type 2 diabetes or for weight management, Wegovy has a special indication that none of the others have. In March 2024, Wegovy acquired an indication to decrease cardiac risk in those with a BMI ≥ 27 and a previous cardiac history. This will really change the accessibility of this medication because patients with heart conditions who are on Medicare are expected to have access to Wegovy.

Tirzepatide. Another weekly injection for treatment of type 2 diabetes is called Mounjaro. Its counterpart for weight management is called Zepbound, which was found to have about 20.9% weight loss over 72 weeks. These medications have similar side effects in differing degrees, but the most-often reported are nausea, stool changes, abdominal pain, and reflux. There are some other potential side effects; I recommend that you read the individual prescribing information available for each drug to have more clarity about that.

It is important that we stay on label for using the GLP-1 receptor agonists, for many reasons. One, it increases our patients’ accessibility to the right medication for them, and we can also make sure that we’re treating the patient with the right drug according to the clinical trials. When the clinical trials are done, the study populations demonstrate safety and efficacy for that population. But if we’re prescribing a GLP-1 for a different population, it is considered off-label use.

Thirty years ago I had an experience in the office that influenced my approach to obesity for the rest of my career. The patient was a 4-year-old whom I had been seeing since her birth. At her annual well-child visit her weight had jumped up significantly from the previous year’s visit. She appeared well, but the change in her growth trajectory prompted a bit more in-depth history taking.

It turned out that finances had forced the family to employ one of the child’s grandmothers as the day care provider. Unfortunately, this grandmother’s passion was cooking and she was particularly adept at baking. She had no other hobbies and a sore hip limited her mobility, so she seldom went outside. When I eventually met her she was a cheerful, overweight, and delightful woman.

Wilkoff_William_G_2_web.jpg

Deconstructing this obesogenic environment without disrupting this otherwise healthy family was an exercise that required tact, patience, and creativity. Fortunately, the young girl’s mother had already harbored some concerns about her child’s weight and was more than willing to participate in this environmental re-engineering project. It’s a long story, but she and I achieved our goals and the child eventually coasted back toward her previous growth curve.

I have always suspected that this scenario is being replayed hundreds of thousands of time across this country. But, sadly most don’t share this one’s happy ending. Parents don’t alway perceive the seriousness of the problem. The economic hurdles are often too steep to overcome, even when the most creative minds are involved.

How prevalent are obesogenic day care environments? We certainly know childhood obesity is a problem and the statistics in the preschool age group are particularly concerning. More than 14 million children are in non-parental early care and education programs; these environments would seem to be a logical place to target our prevention strategies. Understandably, there seems to be a hesitancy to point fingers, but how many day care providers are similar to the well-intentioned grandmother in the scenario I described? We must at least suspect that the example set by the adults in the preschool and day care environment might be having some influence on the children under their care.

There has been some research that sheds some light on this question. A paper from the University of Oklahoma has looked at the predictors of overweight and obesity in early care and education (ECE) teachers in hopes of “finding modifiable opportunities to enhance the health of this critical workforce.” In their paper, the investigators refer to other research that has found the prevalence of overweight and obesity among ECE teachers is higher than our national average and their waist circumference is significantly greater than the standard recommendation for women.

A study from Norway has looked at the association between preschool staff’s activity level and that of the children under their care using accelerometers. This particular investigation couldn’t determine whether it was the staff’s activity level that influenced the children or vice versa because it wasn’t an observational study. Common sense would lead one to believe it was the staff’s relative inactivity that was being reflected in the children’s.

It is interesting that in this Norwegian study when the teachers were asked about their attitudes toward activity and their self-perception of their own activity, there was no relationship between the staff’s and the children’s level of activity. In other words, the educators and caregivers bought into the importance of activity but had difficulty translating this philosophy into own behavior.

So where does this leave us? It turns out my experience decades ago was not a one-off event, but instead represents the tip of very large iceberg. Should we immediately create a system of day care provider boot camps? Let’s remember that each educator and caregiver is one of us. They may be slight outliers but not a group of individuals deserving of forced marches and half-rations to get them in shape.

ECEs have listened to the same message we have all heard about diet and activity and their importance for a child’s health. Our challenge is to create effective, yet sensitive, strategies to help the educators and caregivers modify their dietary habits behaviors in a way that helps them be a more positive influence on their students. It’s for their own health and that of their charges. This could be as simple as providing accelerometers or step-counting smartwatches. Or, by having physical educators perform on-site audits that could then be used to create site-specific plans for increasing both teacher and student activity.

Modifying the educators’ diet is a more complex procedure and can quickly become entangled in the socio-economic background of each individual teacher. A healthy diet is not always equally available to everyone. The solution may involve providing the teachers with food to be eaten at work and to be prepared at home. But, creative answers can be found if we look for them.

Before we get too far down the obesity-is-a-disease pathway, we must take a closer look at the role the early care and early school milieu are playing in the obesity problem. A little common sense behavior modification when children are in the controlled environment of school/day care may allow us to be less reliant on the those new wonder drugs in the long run.

Deconstructing this obesogenic environment without disrupting this otherwise healthy family was an exercise that required tact, patience, and creativity. Fortunately, the young girl’s mother had already harbored some concerns about her child’s weight and was more than willing to participate in this environmental re-engineering project. It’s a long story, but she and I achieved our goals and the child eventually coasted back toward her previous growth curve.

I have always suspected that this scenario is being replayed hundreds of thousands of time across this country. But, sadly most don’t share this one’s happy ending. Parents don’t alway perceive the seriousness of the problem. The economic hurdles are often too steep to overcome, even when the most creative minds are involved.

How prevalent are obesogenic day care environments? We certainly know childhood obesity is a problem and the statistics in the preschool age group are particularly concerning. More than 14 million children are in non-parental early care and education programs; these environments would seem to be a logical place to target our prevention strategies. Understandably, there seems to be a hesitancy to point fingers, but how many day care providers are similar to the well-intentioned grandmother in the scenario I described? We must at least suspect that the example set by the adults in the preschool and day care environment might be having some influence on the children under their care.

There has been some research that sheds some light on this question. A paper from the University of Oklahoma has looked at the predictors of overweight and obesity in early care and education (ECE) teachers in hopes of “finding modifiable opportunities to enhance the health of this critical workforce.” In their paper, the investigators refer to other research that has found the prevalence of overweight and obesity among ECE teachers is higher than our national average and their waist circumference is significantly greater than the standard recommendation for women.

A study from Norway has looked at the association between preschool staff’s activity level and that of the children under their care using accelerometers. This particular investigation couldn’t determine whether it was the staff’s activity level that influenced the children or vice versa because it wasn’t an observational study. Common sense would lead one to believe it was the staff’s relative inactivity that was being reflected in the children’s.

It is interesting that in this Norwegian study when the teachers were asked about their attitudes toward activity and their self-perception of their own activity, there was no relationship between the staff’s and the children’s level of activity. In other words, the educators and caregivers bought into the importance of activity but had difficulty translating this philosophy into own behavior.

So where does this leave us? It turns out my experience decades ago was not a one-off event, but instead represents the tip of very large iceberg. Should we immediately create a system of day care provider boot camps? Let’s remember that each educator and caregiver is one of us. They may be slight outliers but not a group of individuals deserving of forced marches and half-rations to get them in shape.

ECEs have listened to the same message we have all heard about diet and activity and their importance for a child’s health. Our challenge is to create effective, yet sensitive, strategies to help the educators and caregivers modify their dietary habits behaviors in a way that helps them be a more positive influence on their students. It’s for their own health and that of their charges. This could be as simple as providing accelerometers or step-counting smartwatches. Or, by having physical educators perform on-site audits that could then be used to create site-specific plans for increasing both teacher and student activity.

Modifying the educators’ diet is a more complex procedure and can quickly become entangled in the socio-economic background of each individual teacher. A healthy diet is not always equally available to everyone. The solution may involve providing the teachers with food to be eaten at work and to be prepared at home. But, creative answers can be found if we look for them.

Before we get too far down the obesity-is-a-disease pathway, we must take a closer look at the role the early care and early school milieu are playing in the obesity problem. A little common sense behavior modification when children are in the controlled environment of school/day care may allow us to be less reliant on the those new wonder drugs in the long run.

VIENNA — The glucagon-like peptide 1 (GLP-1) receptor agonist semaglutide (Wegovy) not only induced weight loss but also improved knee pain in people with knee osteoarthritis (OA) and obesity, according to results from the STEP 9 study reported at the Osteoarthritis Research Society International (OARSI) 2024  World Congress.

From baseline to week 68, the mean change in knee pain assessed using the Western Ontario and McMaster Universities Arthritis Index (WOMAC) pain score was a reduction of 41.7 points for semaglutide and a decrease of 27.5 points for a matching placebo. The estimated treatment difference of 14.1 points between the groups was statistically significant (P < .001).

As for weight loss, this also fell by a significantly greater amount in the people treated with semaglutide vs those given placebo, with respective reductions of 13.7% and 3.2% from baseline, with an estimated 10.5% greater weight loss with semaglutide.

“The interesting thing is whether there’s a specific action of GLP-1 receptor agonists on the joint, not through the weight loss but by itself,” principal study investigator Henning Bliddal, MD, DMSc, told this news organization ahead of reporting the results at OARSI 2024.

Weight loss is “obviously good” because “the knees suffer from the weight. But whether it’s good for the knee or just for the health or the well-being of the person is another matter,” said Dr. Bliddal, who is director of the Parker Institute at Bispebjerg Frederiksberg Hospital in Copenhagen, Denmark.
 

Not Approved in OA

Semaglutide and other potentially weight loss-inducing drugs are not currently indicated for use specifically in OA, Tonia Vincent, MBBS, PhD, told this news organization, and so “I think we have to be very cautious,” she said.

“Weight loss is one of the few things that has been shown to be successful in clinical trials,” said Dr. Vincent, who is a professor of musculoskeletal biology and an honorary rheumatologist at the Kennedy Institute of Rheumatology at Oxford University in Oxford, England.

“People always feel better too when they lose weight, so that helps manage pain. So, I’d be very surprised if there isn’t a benefit,” she added.

“I just think we need to know more about the long-term use of these drugs, whether the healthcare system can afford them, and how we would ration them.”
 

Previous Work

The STEP 9 study is not the first time that Dr. Bliddal has investigated the effects of a GLP-1 receptor agonist in people with knee OA, but it is the first to have shown a significant effect on knee pain.

Previously, results from the LOSEIT trial with liraglutide demonstrated that, after an 8-week dietary intervention run-in phase, people who were treated with the GLP-1 receptor agonist lost an average of 2.8 kg in body weight over a period of 1 year, vs a 1.2 kg gain in the placebo group. Knee injury and Osteoarthritis Outcome Scores, however, were largely unaffected.

“The study was more or less negative for knee pain because at that time we had to pretreat patients with some kind of weight loss before they were allowed to have the liraglutide,” Dr. Bliddal said.

“There’s so many different considerations with diets and the different ways that [dietary modification] is performed, that could be part of the explanation why some people didn’t find the pain relief,” Dr. Bliddal suggested.
 

STEP 9 Study Design

No pre-study dietary intervention was required in the STEP 9 trial, although a reduced-calorie diet and increased physical exercise were used alongside both semaglutide and placebo treatment.

STEP 9 was a multicenter, multinational phase 3 clinical trial that enrolled people if they had a body mass index (BMI) of > 30, had a clinical diagnosis of knee OA with moderate radiographic changes (Kellgren-Lawrence grade of 2-3), and were experiencing knee pain.

In addition to a baseline WOMAC pain score of at least 40 points (where 0 represents no and 100 the worst pain), the participants had to have a WOMAC numerical rating scale (NRS) score of ≥ 3.1.

A total of 407 participants were recruited and randomly allocated, 2:1, to receive once-weekly subcutaneous injections of either semaglutide 2.4 mg or placebo for a total of 68 weeks.

Dr. Bliddal presented demographic information only for the study population as a whole, showing that the mean was 56 years, 81.6% were women, 60.9% were White, 11.8% Native American, 7.6% Black, and 19.7% of other ethnic origin.

Moreover, the mean bodyweight at baseline was 108.6 kg, and the mean baseline BMI was 40.3, with 75% of participants having a BMI ≥ 35. The mean waist circumference was 118.7 cm. The mean baseline WOMAC pain score was 70.9.
 

Other Findings

In addition to the reductions seen in the coprimary endpoints of weight loss and knee pain, the WOMAC physical function score was also reduced from baseline to week 68 to a greater degree in the semaglutide than placebo arm, by a respective 41.5 vs 26.7 points, with a significant estimated treatment difference of -14.9 points.

“The use of pain medication went down as well; you can see the drop was faster in the semaglutide group than the placebo group, and it was maintained throughout the study,” Dr. Bliddal said during his presentation. He noted that patients had to temporarily stop taking pain relievers such as acetaminophen 3 days before their pain was assessed.

Additional findings reported in the abstract, but not presented at the meeting, were a significant estimated treatment difference of -1.0 in NRS pain intensity, more people treated with semaglutide than placebo achieving ≥ 5% (87.0% vs 29.2%) or ≥ 10% (70.4% vs 9.2%) weight loss.

“Safety and tolerability with semaglutide were consistent with the global STEP program and the GLP-1 receptor agonist class in general,” Dr. Bliddal reported.

Serious adverse events occurred in a respective 10.0% and 8.1% of participants, and adverse events leading to discontinuation were recorded in 6.7% and 3%. Around one third (2.2%) of those leading to discontinuation in the semaglutide arm were gastrointestinal adverse events.

The STEP 9 study was funded by Novo Nordisk. Henning is a principal investigator for the trial and acknowledged that research grants were received from Novo Nordisk to his institution, as well as consulting fees and honoraria. He has also received congress and travel support from Contura. Dr. Vincent was not involved in the study and had no relevant conflicts of interest to disclose.

Recent headlines scream that we have an obesity problem and that carbs are the culprit for the problem. That leads me to ask: How did we get to blaming carbs as the enemy in the war against obesity?

First, a quick review of the history of diet and macronutrient content.

A long time ago, prehistoric humans foraged and hunted for food. Protein and fat were procured from animal meat, which was very important for encephalization, or evolutionary increase in the complexity or relative size of the brain. Most of the requirements for protein and iron were satisfied by hunting and eating land animals as well as consuming marine life that washed up on shore.

Carbohydrates in the form of plant foods served as the only sources of energy available to prehistoric hunter-gatherers, which offset the high protein content of the rest of their diet. These were only available during spring and summer.

Then, about 10,000 years ago, plant and animal agriculture began, and humans saw a permanent shift in the macronutrient content of our daily intake so that it was more consistent and stable. Initially, the nutrient characteristic changes were subtle, going from wild food to cultivated food with the Agricultural Revolution in the mid-17th century. Then, it changed even more rapidly less than 200 years ago with the Industrial Revolution, resulting in semiprocessed and ultraprocessed foods.

This change in food intake altered human physiology, with major changes in our digestive, immune, and neural physiology and an increase in chronic disease prevalence. The last 50 years has seen an increase in obesity in the United States, along with increases in chronic disease such as type 2 diabetes, which leads cardiovascular disease and certain cancers. 
 

Back to Carbohydrates: Do We Need Them? How Much? What Kind?

The increase in the macronutrient content of the food we eat containing saturated fat and refined carbohydrates and sugars represents a major change and is arguably the smoking gun of the obesity epidemic. Unfortunately, ultraprocessed foods have become a staple of the standard American or Western diet. 

Ultraprocessed foods such as cakes, cookies, crackers, sugary breakfast cereals, pizza, potato chips, soft drinks, and ice cream are eons away from our prehistoric diet of wild game, nuts, fruits, and berries, at which time, our digestive immune and nervous systems evolved. The pace at which ultraprocessed foods have entered our diet outpaces the time necessary for adaptation of our digestive systems and genes to these foods. They are indeed pathogenic in this context. 

So when was the time when humans consumed an “optimal” diet? This is hard to say because during the time of brain evolution, we needed protein and iron and succumbed to infections and trauma. In the early 1900s, we continued to succumb to infection until the discovery of antibiotics. Soon thereafter, industrialization and processed foods led to weight gain and the chronic diseases of the cardiovascular system and type 2 diabetes. 

Carbohydrates provide calories and fiber and some micronutrients, which are needed for energy, metabolism, and bowel and immune health. But how much do we need? 

Currently in the United States, the percentage of total food energy derived from the three major macronutrients is: carbohydrates, 51.8%; fat, 32.8%; and protein, 15.4%. Current advice for a healthy diet to lower risk for cardiovascular disease is to limit fat intake to 30% of total energy, protein to 15%, and to increase complex carbohydrates to 55%-60% of total energy. But we also need to qualify this in terms of the quality of the macronutrient, particularly carbohydrates. 

In addition to the quality, the macronutrient content of the diet has varied considerably from our prehistoric times when dietary protein intakes were high at 19%-35% of energy at the expense of carbohydrate (22%-40% of energy). 

If our genes haven’t kept up with industrialization, then why do we need so many carbohydrates to equate to 55%-60% of energy? Is it possible that we are confusing what is available with what we actually need? What do I mean by this?

We certainly have changed the landscape of the world due to agriculture, which has allowed us to procreate and feed ourselves, and certainly, industrialization has increased the availability of accessible cheap food. Protein in the form of meat, fish, and fowl are harder to get in industrialized nations as are fruits and vegetables. These macronutrients were the foods of our ancestors. It may be that a healthy diet is considered the one that is available. 

For instance, the Mediterranean diet is somewhat higher in fat content, 40%-50% fat (mostly mono and unsaturated), and similar in protein content but lower in carbohydrate content than the typical Western diet. The Dietary Approaches to Stop Hypertension (DASH) diet is lower in fat at 25% total calories, is higher in carbohydrates at 55%, and is lower in protein, but this diet was generated in the United States, therefore it is more Western. 

We need high-quality protein for organ and muscle function, high-quality unsaturated and monounsaturated fats for brain function and cellular functions, and high-quality complex carbohydrates for energy and gut health as well as micronutrients for many cellular functions. A ketogenic diet is not sustainable in the long-term for these reasons: chiefly the need for some carbohydrates for gut health and micronutrients. 

How much carbohydrate content is needed should take into consideration energy expenditure as well as micronutrients and fiber intake. Protein and fat can contribute to energy production but not as readily as carbohydrates that can quickly restore glycogen in the muscle and liver. What’s interesting is that our ancestors were able to hunt and run away from danger with the small amounts of carbohydrates from plants and berries plus the protein and fat intake from animals and fish — but the Olympics weren’t a thing then!

It may be another 200,000 years before our genes catch up to ultraprocessed foods and the simple carbohydrates and sugars contained in these products. Evidence suggests that ultraprocessed foods cause inflammation in organs like the liver, adipose tissue, the heart, and even the brain. In the brain, this inflammation may be what’s causing us to defend a higher body weight set point in this environment of easily obtained highly palatable ultraprocessed foods. 

Let’s not wait until our genes catch up and our bodies tolerate junk food without disease progression. It could be like waiting for Godot!

In the early 1900s, we continued to succumb to infection until the discovery of antibiotics. Soon thereafter, industrialization and processed foods led to weight gain and the chronic diseases of the cardiovascular system and type 2 diabetes. 

Carbohydrates provide calories and fiber and some micronutrients, which are needed for energy, metabolism, and bowel and immune health. But how much do we need? 

Currently in the United States, the percentage of total food energy derived from the three major macronutrients is: carbohydrates, 51.8%; fat, 32.8%; and protein, 15.4%. Current advice for a healthy diet to lower risk for cardiovascular disease is to limit fat intake to 30% of total energy, protein to 15%, and to increase complex carbohydrates to 55%-60% of total energy. But we also need to qualify this in terms of the quality of the macronutrient, particularly carbohydrates. 

In addition to the quality, the macronutrient content of the diet has varied considerably from our prehistoric times when dietary protein intakes were high at 19%-35% of energy at the expense of carbohydrate (22%-40% of energy). 

If our genes haven’t kept up with industrialization, then why do we need so many carbohydrates to equate to 55%-60% of energy? Is it possible that we are confusing what is available with what we actually need? What do I mean by this?

We certainly have changed the landscape of the world due to agriculture, which has allowed us to procreate and feed ourselves, and certainly, industrialization has increased the availability of accessible cheap food. Protein in the form of meat, fish, and fowl are harder to get in industrialized nations as are fruits and vegetables. These macronutrients were the foods of our ancestors. It may be that a healthy diet is considered the one that is available. 

For instance, the Mediterranean diet is somewhat higher in fat content, 40%-50% fat (mostly mono and unsaturated), and similar in protein content but lower in carbohydrate content than the typical Western diet. The Dietary Approaches to Stop Hypertension (DASH) diet is lower in fat at 25% total calories, is higher in carbohydrates at 55%, and is lower in protein, but this diet was generated in the United States, therefore it is more Western. 

We need high-quality protein for organ and muscle function, high-quality unsaturated and monounsaturated fats for brain function and cellular functions, and high-quality complex carbohydrates for energy and gut health as well as micronutrients for many cellular functions. A ketogenic diet is not sustainable in the long-term for these reasons: chiefly the need for some carbohydrates for gut health and micronutrients. 

How much carbohydrate content is needed should take into consideration energy expenditure as well as micronutrients and fiber intake. Protein and fat can contribute to energy production but not as readily as carbohydrates that can quickly restore glycogen in the muscle and liver. What’s interesting is that our ancestors were able to hunt and run away from danger with the small amounts of carbohydrates from plants and berries plus the protein and fat intake from animals and fish — but the Olympics weren’t a thing then!

It may be another 200,000 years before our genes catch up to ultraprocessed foods and the simple carbohydrates and sugars contained in these products. Evidence suggests that ultraprocessed foods cause inflammation in organs like the liver, adipose tissue, the heart, and even the brain. In the brain, this inflammation may be what’s causing us to defend a higher body weight set point in this environment of easily obtained highly palatable ultraprocessed foods. 

Let’s not wait until our genes catch up and our bodies tolerate junk food without disease progression. It could be like waiting for Godot!

Recent headlines scream that we have an obesity problem and that carbs are the culprit for the problem. That leads me to ask: How did we get to blaming carbs as the enemy in the war against obesity?

First, a quick review of the history of diet and macronutrient content.

A long time ago, prehistoric humans foraged and hunted for food. Protein and fat were procured from animal meat, which was very important for encephalization, or evolutionary increase in the complexity or relative size of the brain. Most of the requirements for protein and iron were satisfied by hunting and eating land animals as well as consuming marine life that washed up on shore.

Carbohydrates in the form of plant foods served as the only sources of energy available to prehistoric hunter-gatherers, which offset the high protein content of the rest of their diet. These were only available during spring and summer.

Then, about 10,000 years ago, plant and animal agriculture began, and humans saw a permanent shift in the macronutrient content of our daily intake so that it was more consistent and stable. Initially, the nutrient characteristic changes were subtle, going from wild food to cultivated food with the Agricultural Revolution in the mid-17th century. Then, it changed even more rapidly less than 200 years ago with the Industrial Revolution, resulting in semiprocessed and ultraprocessed foods.

This change in food intake altered human physiology, with major changes in our digestive, immune, and neural physiology and an increase in chronic disease prevalence. The last 50 years has seen an increase in obesity in the United States, along with increases in chronic disease such as type 2 diabetes, which leads cardiovascular disease and certain cancers. 
 

Back to Carbohydrates: Do We Need Them? How Much? What Kind?

The increase in the macronutrient content of the food we eat containing saturated fat and refined carbohydrates and sugars represents a major change and is arguably the smoking gun of the obesity epidemic. Unfortunately, ultraprocessed foods have become a staple of the standard American or Western diet. 

Ultraprocessed foods such as cakes, cookies, crackers, sugary breakfast cereals, pizza, potato chips, soft drinks, and ice cream are eons away from our prehistoric diet of wild game, nuts, fruits, and berries, at which time, our digestive immune and nervous systems evolved. The pace at which ultraprocessed foods have entered our diet outpaces the time necessary for adaptation of our digestive systems and genes to these foods. They are indeed pathogenic in this context. 

So when was the time when humans consumed an “optimal” diet? This is hard to say because during the time of brain evolution, we needed protein and iron and succumbed to infections and trauma. In the early 1900s, we continued to succumb to infection until the discovery of antibiotics. Soon thereafter, industrialization and processed foods led to weight gain and the chronic diseases of the cardiovascular system and type 2 diabetes.

LONDON — Weight loss, glycemic control, fatty liver, and the need for insulin all showed improvement in patients with both refractory type 2 diabetes and obesity after a gut liner known as EndoBarrier (RESET, Morphic Medical, United States) was implanted for 1 year, showed data.

Two years after the liner’s removal, 80% of patients continued to show significant improvement, while 20% returned to baseline.

Presenting results at the Diabetes UK Professional Conference (DUKPC) 2024, the researchers, led by Bob Ryder, MD, FRCP, from the Department of Diabetes, Birmingham City Hospital, Birmingham, England, aimed to assess the safety and efficacy of EndoBarrier, as well as maintenance of efficacy 24 months after the device removal.

“We think EndoBarrier finds its place between the end of all the earlier measures and the possible option of bariatric surgery, and these data show that it can lead to tremendous weight loss and improvement in A1c,” Dr. Ryder said in an interview.

Commenting on how most patients had responded to use of the device, Dr. Ryder said, “People with obesity are often very unhappy and have tried everything over many years to no effect; however, this gut liner provided the opportunity to shift out of this state, and they often become so happy with the result they were determined to stick with it and continue with a healthier lifestyle including much more exercise.”
 

Convenient, Reversible Procedure

Ninety consecutive patients from Birmingham, all with longstanding, poorly controlled, type 2 diabetes and obesity, underwent the implantation procedure, and 60 of these attended follow-up visits 2 years post implantation.

Unlike permanent and more invasive weight loss surgeries, the EndoBarrier device is reversible and fitted with a straightforward procedure.

The thin impermeable sleeve is inserted via an approximate 1-hour endoscopy, enabling the patient to return home the same day. It lines the first 60 cm of the small intestine. Digested food passes through it without absorption and then makes contact with pancreatic and bile juices at the other end. This triggers a change in the metabolism of glucose and nutrients through modulating gut hormones and gut bacteria, as well as disrupting bile flow.

“Because the food bypasses the small intestine, the first time the food is encountered is in an area where it is not normally found, and this causes a reaction where signals are sent to the brain to stop eating,” explained Dr. Ryder.

Due to a license for 1 year of use, the gut liner was removed after a year via a 30-minute endoscopy procedure.
 

Over Half Maintained Full Improvement 2 Years Post Removal

A total of 60/90 (66%) attended follow-up visits and comprised the data presented. Mean age was 51.2 years, 47% were men, 50% were White, mean body mass index (BMI) was 41.5 kg/m², and mean A1c was 9.3%. Duration of type 2 diabetes was a median of 11 years, and 60% were taking insulin.

Patients followed dietary requirements for the initial phase after implantation. “During the first week, they followed a liquid diet, then during week 2 — mushy food, and then they were told to chew it really well to avoid blockage,” said Dr. Ryder.

Mean weight loss on removal of the liner (at 12 months post implantation) was 16.7 kg (P < .001), while BMI dropped by mean 6 kg/m², A1c dropped by a mean of 1.8%, and mean systolic blood pressure by 10.9 mm Hg.

Just over half (32/60, 53%) showed maintenance of fully sustained improvement 2 years after removal of the liner — defined as no significant difference after 2 years between weight loss (mean, 96-97 kg) and similarly for A1c improvement (7.6%-7.4%).

Sixteen of 60 (27%) showed partially sustained improvement over the 2 years of follow-up, with BMI increasing from a mean of 116.8 kg to 128.6 kg and A1c increasing from 7.5% to 8.4%. While 20% (12/60) returned to baseline.

Of the 36/60 people using insulin prior to EndoBarrier treatment, 10 (27.8%) were no longer using insulin at 2 years post removal.

Thirteen of 90 (14%) had early removal of the gut liner due to gastrointestinal hemorrhage (five), liver abscess (two), other abscess (one), and gastrointestinal symptoms (five), but they all made a full recovery; after removal, most experienced benefit despite the adverse event, reported Dr. Ryder.

Sarah Davies, MBBCh, a GP at Woodlands Medical Centre, Cardiff, Wales, agreed that EndoBarrier might be a viable option for patients struggling with obesity. “As GPs, we are the first port of call for these patients. It’s very novel, I hadn’t heard of it before. I like how it’s a noninvasive way for my patients to lose weight and maintain that even after EndoBarrier has been removed.”

Outcomes are being monitored in an ongoing global registry to help determine if EndoBarrier is a safe and effective treatment for individuals with type 2 diabetes and obesity. Dr. Ryder noted that a similar study with 3 years of follow-up showed similar results. Further results will be presented by Dr. Ryder at the upcoming meeting of the American Diabetes Association.

EndoBarrier is currently not approved in the United States. It is awaiting United Kingdom and European CE mark, which the manufacturer hope will be granted this summer. The license will be for patients with BMI of 35-50 kg/m².

Results from a preliminary clinical trial demonstrated the obesity drug, tirzepatide, effectively treated obstructive sleep apnea (OSA), according to information sent to investors of the pharmaceutical company, Eli Lilly.

Indiana-based Eli Lilly sells tirzepatide under the brand name Zepbound, which was approved by the FDA in November to treat overweight and obesity. Tirzepatide is also marketed under the name Mounjaro to treat diabetes, and it’s among the same class of drugs as other well-known weight loss and diabetes drugs like Ozempic and Wegovy.

The newly announced results came from a pair of studies that followed people with moderate to severe OSA who also had obesity. People in the study took tirzepatide, which is given by injection, for one year. One study evaluated people who were using CPAP during sleep, and another study included people who didn’t use the device. People in both studies taking tirzepatide had significant reductions in sleep events and also lost about 20% of body weight. About 70% of people in the studies were men.

The findings have not yet been published in a peer-reviewed medical journal, and the preliminary results were announced by Eli Lilly because of reporting requirements related to information that could affect stock prices. The company indicated that detailed results will be presented at a conference of the American Diabetes Association in June and will be submitted to a peer-reviewed journal for consideration of publication. The company also plans to submit the information to the FDA for approval consideration mid-year, the investor news release stated.

People in the study taking tirzepatide on average experienced 63% fewer instances of reduced oxygen due to breathing changes, or events when breathing entirely stopped, Eli Lilly reported.

A sleep expert from Washington University in St. Louis told The New York Times the initial findings were extremely positive and noted that tirzepatide works to treat the underlying cause of sleep apnea, rather than current treatments that just address symptoms.

Tirzepatide “is a great alternative for people who are obese and can’t use CPAP or are on CPAP and want to improve the effect,” Eric Landsness, MD, PhD, told The New York Times. 

Eli Lilly indicated the most commonly reported adverse events in the studies were diarrhea, nausea, vomiting, and constipation.

An estimated 39 million people have OSA and about 33 million people use CPAP machines, according to The National Council on Aging. The condition has been increasingly diagnosed in recent years and becomes more likely to affect people as they get older.

Here’s a new direction for smartphones in healthcare. 

Researchers from the National Institute of Standards and Technology (NIST), Boulder, Colorado, say a smartphone compass could be used to analyze biomarkers in body fluids — blood, sweat, urine, or saliva — to monitor or diagnose disease.

“We’re just at this point demonstrating this new way of sensing that we hope [will be] very accessible and very portable,” said Gary Zabow, PhD, a group leader in the applied physics division at NIST who supervised the research. 

In a proof-of-concept study, the researchers measured glucose levels in sangria, pinot grigio, and champagne. The detection limit reached micromolar concentrations — on par with or better than some widely used glucose sensors, such as continuous glucose monitors. They also accurately measured the pH levels of coffee, orange juice, and root beer.

More tests are needed to confirm the method works in biological fluids, so it could be a while before it’s available for clinical or commercial use. 

Still, the prospect is “exciting,” said Aydogan Ozcan, PhD, a bioengineering professor at the University of California, Los Angeles, who was not involved in the study. “It might enable new capabilities for advanced sensing applications in field settings or even at home.”

The advance builds on growing research using smartphones to put powerful medical devices in patients’ hands. A new AI-powered app can use a smartphone camera to detect skin cancer, while other apps administer cognitive tests to detect dementia. Smartphone cameras can even be harnessed for “advanced optical microscopes and sensors to the level where we could even see and detect individual DNA molecules with inexpensive optical attachments,” Dr. Ozcan said. More than six billion people worldwide own a smartphone.

The compass inside smartphones is a magnetometer — it measures magnetic fields. Normally it detects the earth’s magnetic fields, but it can also detect small, nearby magnets and changes in those magnets’ positions. 

The researchers embedded a small magnet inside a strip of “smart hydrogel — a piece of material that expands or contracts” when immersed in a solution, said Dr. Zabow.

As the hydrogel gets bigger or smaller, it moves the magnet, Dr. Zabow explained. For example, if the hydrogel is designed to expand when the solution is acidic or contract when it’s basic, it can move the magnet closer or farther from the phone’s magnetometer, providing an indicator of pH. For glucose, the hydrogel expands or contracts depending on the concentration of sugar in the liquid.

With some calibration and coding to translate that reading into a number, “you can effectively read out glucose or pH,” Dr. Zabow said.

Only a small strip of hydrogel is needed, “like a pH test strip that you use for a pool,” said first study author Mark Ferris, PhD, a postdoctoral researcher at NIST. 

Like a pool pH test strip, this test is meant to be “easy to use, and at that kind of price,” Dr. Ferris said. “It’s supposed to be something that’s cheap and disposable.” Each pH hydrogel strip is about 3 cents, and glucose strips are 16 cents, Dr. Ferris estimated. In bulk, those prices could go down.

Next the team plans to test the strips with biological fluids. But complex fluids like blood could pose a challenge, as other molecules present could react with the strip and affect the results. “It may be that you need to tweak the chemistry of the hydrogel to make sure it is really specific to one biomolecule and there is no interference from other biomolecules,” Dr. Zabow said.

The technique could be adapted to detect other biomarkers or molecules, the researchers said. It could also be used to check for chemical contaminants in tap, lake, or stream water.

TOPLINE:

Biscuits reformulated with the sweeteners and sweetness enhancers (S&SEs) neotame and stevia rebaudioside M (StRebM) yield appetite responses similar to those of sucrose-sweetened ones but decrease post-meal insulin and glucose levels in adults with overweight or obesity.

METHODOLOGY:

• In 2023, the World Health Organization issued a conditional recommendation that S&SE should not be used for weight control, apparently due to a lack of evidence for a clear benefit and weak evidence linking S&SE intake with excess weight and poorer health outcomes.
• This randomized crossover trial, conducted in England and France between 2021 and 2022, evaluated the acute (1 day) and repeated (daily for 2 weeks) effects of S&SEs vs sucrose in solid food on appetite and endocrine responses in adults with overweight or obesity.
• Overall, 53 adults (33 women, 20 men; aged 18-60 years) with overweight or obesity consumed biscuits with fruit filling containing either sucrose or reformulated with the S&SEs StRebM or neotame, daily for three 2-week intervention periods separated by a washout period of 14-21 days.
• Participants were required to fast for 12 hours before attending a laboratory session at the beginning (day 1) and end (day 14) of each consumption period.
• The primary endpoint was the composite appetite score, while secondary endpoints included food preferences, postprandial glucose and insulin response, and other satiety-related peptides, such as ghrelin, glucagon-like peptide 1, and pancreatic polypeptide.

TAKEAWAY:

• The composite appetite scores were comparable between the sucrose, StRebM, and neotame groups, with lower appetite suppression observed on day 14 than on day 1 for all three formulations.
• Neotame (P < .001) and StRebM (P < .001) lowered postprandial insulin levels compared with sucrose, while glucose levels saw a decline only with StRebM (and not with neotame) compared with sucrose (P < .05).
• The S&SEs had no effect on satiety levels, as any acute or repeated exposures to StRebM or neotame vs sucrose did not affect the ghrelin and glucagon-like peptide-1 responses.
• Gastrointestinal issues were more frequently reported in the neotame and StRebM groups than in the sucrose group.

IN PRACTICE:

“There is no detrimental impact of replacing sugar with S&SE in these endpoints,” the authors wrote. “Additionally, glucose and insulin responses were blunted after acute and repeated consumption of S&SE-reformulated biscuits, which may confer a benefit for blood glucose control, for example, in individuals at risk of developing type 2 diabetes.”

SOURCE:

This study was led by Catherine Gibbons, School of Psychology, Faculty of Medicine and Health, University of Leeds, England. It was published online in eBioMedicine.

LIMITATIONS:

The reformulated products required the addition of polyol bulking agents (8% maltitol and 8% sorbitol) to match the biscuits in sensory qualities as closely as possible. Gastrointestinal symptoms (initial bloating and flatulence) in the neotame and StRebM formulations may be due to the polyols, classed as low-digestible carbohydrates.

DISCLOSURES:

This study received funding from a European Union Horizon 2020 program, SWEET (Sweeteners and sweetness enhancers: Impact on health, obesity, safety, and sustainability). The authors reported receiving funding and honoraria from the food and beverage industry and trade groups from various entities.

TOPLINE:

Endoscopic sleeve gastroplasty (ESG) is more cost-effective, and achieves and sustains greater weight loss, than semaglutide over a 5-year period in patients with class II obesity.

METHODOLOGY:

• Researchers used a Markov cohort model to assess the cost-effectiveness of semaglutide vs ESG over 5 years in people with class II obesity (body mass index [BMI], 35-39.9), with the model costs based on the US healthcare system.
• A 45-year-old patient with a BMI of 37 was included as the base case in this study.
• The model simulated hypothetical patients with class II obesity who received ESG, semaglutide, or no treatment (reference group with zero treatment costs).
• The model derived clinical data for the first year from two randomized clinical trials, STEP 1 (semaglutide) and MERIT (ESG); for the following years, data were derived from published studies and publicly available data sources.
• Study outcomes were total costs, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratio (ICER).

TAKEAWAY:

• ESG led to better weight loss outcomes (BMI, 31.7 vs 33.0) and added 0.06 more QALYs relative to semaglutide in the modelled patients over the 5-year time horizon; about 20% of the patients receiving semaglutide dropped out owing to medication intolerance or other reasons.
• The semaglutide treatment was $33,583 more expensive than the ESG treatment over the 5-year period.
• ESG became more cost-effective than semaglutide at 2 years and remained so over a 5-year time horizon, with an ICER of — $595,532 per QALY for the base case.
• The annual price of semaglutide would need to be reduced from $13,618 to $3591 to achieve nondominance compared with ESG.

IN PRACTICE:

“The strategic choice of cost saving yet effective treatment such as ESG compared with semaglutide for specific patient groups could help alleviate the potential budget strain expected from the use of semaglutide,” the authors wrote.

SOURCE:

Muhammad Haseeb, MD, MSc, Division of Gastroenterology, Hepatology and Endoscopy, Brigham and Women’s Hospital, Boston, led this study, which was published online on April 12, 2024, in JAMA Network Open.

LIMITATIONS:

The study did not look at benefits associated with improvements in comorbidities from either treatment strategy, and the model used did not account for any microlevel follow-up costs such as routine clinic visits. The authors acknowledged that semaglutide’s prices may fall in the future when more anti-obesity drugs get approved.

DISCLOSURES:

This study was supported in part by the National Institutes of Health. Some authors declared receiving personal fees, royalty payments, and/or grants and having other ties with several sources.
