Gut microbiome may shape response to GLP-1 drugs, new review suggests

This review examines how GLP-1 receptor agonists and the gut microbiome influence one another through bile acid signaling, short-chain fatty acids, and inflammatory pathways. It explores how microbial composition may shape treatment response and highlights the need for controlled human studies to enable microbiome-informed precision therapy.

Intermittent calorie restriction proves as effective as daily calorie cuts for type 2 diabetes

A post-hoc analysis of two clinical trials compared continuous calorie restriction with early time-restricted eating in adults with type 2 diabetes and overweight or obesity over three months. Both approaches improved weight, body composition, and metabolic health, with no clear superiority except for lower dropout with intermittent restriction.

Higher red meat intake links to greater diabetes odds in large US study

Higher intakes of total, processed, and unprocessed red meat were associated with greater odds of diabetes in a nationally representative sample of US adults. Statistical substitution models suggest replacing red meat with plant proteins, poultry, dairy, or whole grains may be linked to lower diabetes odds, though causality cannot be inferred.

Three daily servings of full-fat dairy do not worsen weight or blood markers

This randomized 12-week trial examined whether adding three daily servings of full-fat dairy to diets aligned with Canada’s Food Guide affects body weight, cardiometabolic markers, and nutrient intake in adults with overweight or obesity. Full-fat dairy intake did not adversely affect weight, body composition, or metabolic health and increased calcium and protein intake, supporting dietary compatibility rather than therapeutic benefit.

Nearly half of adults now live with heart disease as obesity and diabetes surge

The 2026 American Heart Association Heart Disease and Stroke Statistics report shows that nearly half of adults are living with cardiovascular disease, with cardiometabolic risk factors projected to rise substantially by 2050. Despite progress in smoking reduction and cholesterol control, worsening obesity, diabetes, hypertension, sleep health, and persistent inequities threaten future cardiovascular health.
