Healthy Diet May Help With Pain Management, Regardless of Person’s Size

Fhe study found that diet quality could affect pain differently in men and women. Women who consumed a higher quality diet reported lower pain and had better physical function. This effect was less pronounced in men.

WeightControl.com: What is the background for this study?

Response: Chronic pain is a common and disabling health problem, estimated to affect 20-30% of people worldwide. Those who experience chronic pain often have a higher weight compared to the general population. Food choices that influence the overall quality of a person’s diet may contribute to an individual’s pain by affecting their weight or triggering bodily processes such as inflammation.

This study of Australian adults explored whether diet was directly linked to pain, and if factors like weight, or body fat, impacted this relationship. Additionally, the study looked at differences between men and women as chronic pain is more prevalent in women.

WeightControl.com: What is the background for this study?

Response: The recent introduction of glucagon receptor-1 agonists for weight control opens a new era in obesity pharmacotherapy. The greater weight loss with the new drugs is revealing a long-standing recognition that negative energy balance is accompanied by not only decrements in body fat, but also lean protein-containing tissues such as liver, kidney, and skeletal muscle.

WeightControl.com: What is the background for this study?

Response: Our study examines how men and women process food differently, particularly how each sex responds to a high-carb versus a high-fat diet. Obesity and related conditions, like type 2 diabetes, are major global issues, and nutrition plays a key role in managing these conditions.

Men and women metabolize fats and carbohydrates differently, especially during fasting and exercise. Using a mathematical model and computer simulations, we investigated sex differences in the processing of glucose and fat and identified candidate pathways behind these sex-specific differences. This research can help improve personalized nutrition and diet strategies for both men and women.

Cleveland Clinic Study Identifies Factors Associated with Weight Loss Success on Semaglutide or Liraglutide

Researchers found that four in 10 patients (40.7%) were persistent with their medication one year after their initial prescription’s fill. The proportion of patients who were persistent with semaglutide was 45.8% versus 35.6% in patients receiving liraglutide.

WeightControl.com: What is the background for this study?

Response: Recently, injectable forms of GLP-1 RA medications such as semaglutide have been more commonly prescribed, in part related to their ability to demonstrate clinically significant weight reduction. However, outside of randomized trial settings, data on weight loss with semaglutide or liraglutide for obesity is generally limited to 6 months of follow-up, based on brand names approved by the FDA for type 2 diabetes only, or cohorts that exclude patients who did not persist with the medication.

Monell Scientists Locate Region of Brain Activated by GLP1 drugs That Can Reduce Food Intake Without Nausea

Because we found that GLP1 drugs can activate a neuron population in the brain to reduce food intake without nausea, the implication is that future obesity drugs could be developed to selectively promote satiety without the negative side effects.

WeightControl.com: What is the background for this study?

Response: GLP1-based weight loss drugs have become extremely popular, but we don’t have a good understanding of how they work. Further, many people who take these drugs experience nausea and other gastrointestinal side effects – some more severe than others.

Because of this, we became interested in understanding whether the appetite loss and weight loss stem from the same or different neural circuits as those that mediate the nausea.

Real World Study Compares Weight Loss with Semaglutide vs Tirzepatide

While tirzepatide (Mounjaro) was significantly more effective than semaglutide (Ozempic), patients on both medications experienced substantial weight loss and we observed no difference in the risk of GI adverse events.

WeightControl.com: What is the background for this study? What are the main findings?

Response: With over 70% of US adults having overweight or obesity, GLP-1s have the potential to be used by a huge number of people. We’ve seen dramatic increases in use by patients with and without type 2 diabetes in the past year, yet little real-world data exist to compare the effectiveness of two of the most common medications, semaglutide (Ozempic) and tirzepatide (Mounjaro). Head-to-head trials for patients with overweight or obesity are still months away, and even then, it remains unclear how weight loss observed in these randomized controlled trials will generalize to real-world populations. There has been evidence that these medications are effective for weight loss, but it hadn’t been clear just how effective they are, particularly in relation to each other.

While clinical trials don’t always generalize to the real-world, our findings were broadly consistent with placebo-controlled clinical trials, finding that the majority of patients on both medications experience clinically meaningful weight loss within a year on treatment. However, patients on tirzepatide (Mounjaro) were over 2 times more likely to experience 10% weight loss and 3 times more likely to experience 15% weight loss within a year, compared to patients on semaglutide (Ozempic). Our study also found that, in general, patients without type 2 diabetes experienced greater weight loss than patients with type 2 diabetes, but tirzepatide (Mounjaro) was more effective than semaglutide (Ozempic) in both groups.

The study also found a high rate of discontinuation – 55.9% of patients on tirzepatide (Mounjaro), and 52.5% of patients on semaglutide (Ozempic) within 12 months.

Gastrointestinal side effects of these medications have been widely reported as well, but we didn’t find a difference in the rates of moderate to severe gastrointestinal adverse events between the two medications.

Daily Heat Treatments May Reduce Risk of Obesity in Menopausal Women

Daily 30-minute heat treatment is safe and reduces aging-mediated tissue damage. It is a promising and effective therapeutic strategy to boost metabolism and reduce the risk of obesity and metabolic dysfunction.

WeightControl.com: What is the background for this study?

Response: As we age, our metabolism and energy expenditure decline.

Studies have shown that in women, age-related metabolic changes begin around ages 45-50 with a sharp increase, overlapping with the menopause period. This mid-life aging window is crucial and highlights the need for effective and accessible intervention strategies.

Daily whole-body heat treatment (104-113°F) for 30 minutes is a promising strategy to partially mimic the metabolic benefits and physiological response of aerobic exercise.

WeightControl.com: What is the background for this study?

Response: Although we already have substantial evidence of the negative impact of an ultra-processed food-based diet on health, solid public policies to discourage the consumption of these products are still lacking, especially in countries like the United Kingdom. Plant-based foods are recommended in many dietary guidelines, and this area has been explored by the food industry, which uses health claims (vegetarian, vegan, plant-based) to promote its products.

With a growing population adopting plant-based diets, studying the role of food processing in plant-based dietary patterns and its relation to cardiovascular diseases can help refine guidelines to incorporate considerations about food processing in their recommendations.

WeightControl.com: What is the background for this study? How would you describe the procedure?

Response: The purpose of this study was to evaluate the safety and efficacy of Bariatric Arterial Embolization (BAE) in patients who have a BMI greater than or equal to 35. BAE is a minimally invasive interventional radiology treatment that reduces the production of the hunger hormone ghrelin as a result of decreasing the blood flow to the stomach.

There were 10 participants recruited in this study. The participants were followed six weeks before BAE and a year following the procedure. After the procedure, the participants were admitted for routine supportive care for up to 48 hours. The participant’s BMI, weight, and body compensation were measured 1,3,6, and 12 months after the surgery.
