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.

Pennington Study Demonstrates Long-Term Weight Loss Efficacy of Semaglutide

ECO24: Ideal Weight For Patients with Diabetes May Vary with Age

For older individuals who are moderately overweight , maintaining rather than reducing weight may be a more practical goal.

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

Response: In previous studies, the obesity paradox has been observed, where overweight and obese individuals with cardiovascular disease have better outcomes compared to their slim counterparts with the same disease. The global prevalence of diabetes is steadily increasing year by year.

In this era of population growth and aging, the question arises as to whether obesity or overweight can be beneficial in improving survival rates for older individuals with diabetes. This topic holds significant relevance due to the potential implications it has on weight management strategies for older adults. If overweight does not pose an increased risk of cardiovascular mortality, it may suggest that older individuals are not necessarily required to strive for weight loss in order to achieve so-called normal values. Moreover, inappropriate weight loss and being underweight could potentially elevate the risk of cardiovascular events, myocardial infarction, cerebral infarction, and all-cause mortality.

ECO24: Tirzepatide Found Effective for Weight Loss Despite Duration of Obesity

Tirzepatide is a once weekly GIP and GLP-1 receptor agonist while semaglutide was a once weekly GLP-1 receptor agonist

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

Response: The study was a subgroup analysis of SURMOUNT 1-4 aiming to investigate if tirzepatide was effective in terms of percent body weight change, proportions achieving weight loss targets of 5, 10, 15, 20, and 25% and change in waist circumference in subjects with different duration of obesity.

Increased Risk of Dental Cavities after Bariatric Surgery for Obesity

The main findings are that dental caries were more common in those with the highest BMI before treatment and that surgical obesity treatment can increase the frequency of dental caries

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

Response: The original background for the studies was the global obesity epidemic and its consequences. The implications for general health have been the focus of much research, but the impact on oral health has been studied very little.

In recent years, observations of oral health problems after bariatric surgery have been reported from both patients and dentists. However, these have been episodic observations and therefore scientific studies are required. At the same time, a larger medical study was started to follow patients undergoing obesity treatment, medical or surgical, and we were able to include examinations of the mouth and teeth.

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

Ms. Olaniran: The study focused on experiences of discrimination among people with obesity (PWO), based on their characteristics including body size, race/ethnicity, and sex. Discrimination against individuals and groups remains prevalent in the United States. Studies show that perceived discrimination negatively impacts physical and mental health, but how it impacts diverse PWO is not well understood. This study assessed race/ethnic group and sex differences in perceptions of discrimination among people with obesity .

DIETFITS: Identifying Groups with Varying Weight Loss Success

the most successful subgroup (73% met threshold) had high outcome expectations for making health improvements coupled with high levels of family encouragement

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

Response: Lifestyle interventions are the first-line treatment for obesity; however, not all participants achieve clinically significant weight loss.

As researchers and clinicians, we want to minimize patient burden, maximize clinical outcomes, and conserve constraints (budget & personnel).

Using data from a 12-month diet and weight loss intervention (DIETFITS), we examined 52 demographic, clinical, & psychosocial variables among 436 participants (BMI 28-40) to see if there are distinct subgroups of participants who were more or less successful in losing 5% weight by 12 months?

EASD: Analysis Finds More Weight Loss (and side effects) with Tirzepatide in Type 2 Diabetes

Our analysis can help healthcare professionals make informed choices for managing type 2 diabetes, especially for those patients for whom weight loss is an important goal. However, like any medication, it’s crucial to consider the entire profile of tirzepatide, including side effects.

WeightControl.com Interview with:

Dr Thomas Karagiannis MD
Aristotle University of Thessaloniki
Thessaloniki, Greece

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

Response: Previous individual studies have shown that both subcutaneous semaglutide and tirzepatide are very effective in managing blood sugar and reducing body weight in people with type 2 diabetes. However, direct comparisons between these medications have been limited.

In our study, we used a technique called a network meta-analysis to indirectly compare the two. This method allowed us to derive results by examining other trials that compared either of the drugs with placebo or another treatment.

Our findings indicated that tirzepatide had a stronger effect than semaglutide in controlling blood sugar and aiding weight loss. For example, those on the highest dose of tirzepatide lost, on average, 5.7 kg more than those on the highest dose of semaglutide. But, it’s worth mentioning that some side effects, especially related to the digestive system, were slightly more common with the high dose of tirzepatide.

Suzanne Phelan, PhD
Professor of Kinesiology & Public Health
Director, Center for Health Research
California Polytechnic State University

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

Response: Understanding the factors that promote long-term weight control is need to inform health interventions.  We know that self-monitoring, physical activity, and cognitive restraint are associated with success in long-term weight control.  The other behavioral, psychological, and environmental factors remain unclear, and very few studies have examined the factors related to long-term successful weight control in commercial weight management programs, which reach 10-15% of the US population.

Study Finds Almonds Can Be Included in Weight Control Program, with Potential Cardiac Benefits

The amount of weight loss achieved was the same for those who are almonds or an energy matched diet without nuts but those who ate almonds had additional benefits to cardiovascular disease risk factors.

Prof. Alison M. Coates PhD
Allied Health & Human Performance
Alliance for Research in Exercise, Nutrition and Activity (ARENA)
University of South Australia
Adelaide, South Australia, Australia

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

Response: Studies have indicated an inverse association between nut consumption and BMI, suggesting that nut consumption may have a protective effect against accumulation of adiposity. However, despite these findings, there has been a common perception that nut consumption will lead to increased body weight or impair weight loss when a person is trying to lose weight.

Nuts are a core food according to the Australian dietary guidelines and a rich source of good fats, protein, fibre, vitamins and minerals.
Therefore, this study aimed to contribute to the growing research surrounding nuts, specifically to evaluate whether the inclusion of 15% of dietary energy from almonds compared with carbohydrate-rich snacks in an otherwise nut-free diet would improve weight loss during 3 months of dietary energy restriction (~30% reduction) and limit weight regain during 6 months of weight maintenance.
