Combined GLP-1 and GLP-2 treatment appears safe but does not beat placebo for obesity

In a 12-week randomized phase IIa trial in adults with obesity, the dual GLP-1/GLP-2 receptor agonist dapiglutide was well tolerated but did not achieve statistically significant weight loss compared with placebo at 4 mg or 6 mg doses. Although the higher dose showed modest within-group weight reduction and improved HbA1c, unexpectedly substantial placebo-associated weight loss limited the observed treatment effect.

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.

How GLP-1 drugs affect the body beyond weight loss and glucose control

This review evaluates the safety profile of glucagon-like peptide-1 receptor agonists and related incretin therapies used for obesity and type 2 diabetes. It highlights common gastrointestinal effects, rare but debated risks, and areas where further long-term safety data are still needed.

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.

Diabetic nephropathy shows severe biochemical abnormalities

Chronic diabetes mellitus is marked by hyperglycemia and metabolic dysfunction, increasing the risk of complications such as nephropathy.

Magnesium lower fasting blood sugar in older adults

Magnesium boosts fasting glucose control in older adults with deficiency, but preventing diabetes progression may need more than just mineral correction.

Unprocessed beef does not worsen metabolic health in prediabetes

Short-term unprocessed beef intake shows no adverse effects on glucose regulation or metabolic health compared to poultry in individuals with prediabetes.

Why the carnivore diet’s claimed benefits don’t outweigh its health risks

Researchers determine the nutritional adequacy and health effects of the carnivore diet.

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.

High-dose flu shots lower hospitalization risk in older adults

High-dose influenza vaccines may lower serious hospitalization rates in older adults, particularly those with diabetes, according to a recent Danish trial.

PFAS exposure increases gestational diabetes risk

A review of 130 studies links PFAS exposure to gestational diabetes, highlighting the need for further research on diabetes outcomes and environmental factors.

Father's early behavior linked to child's heart and metabolic health years later

How a new father behaves toward his baby can change family dynamics in a way that affects the child's heart and metabolic health years later, according to a new study by researchers in the Penn State College of Health and Human Development.

Simple fruit granola intervention shows promising cardio-renal signals in CKD patients

A single-arm intervention study in Japanese adults with moderate chronic kidney disease found that replacing breakfast with fruit granola for two months lowered systolic blood pressure, reduced LDL-related lipid markers, and decreased a urinary marker of tubular injury. Renal function remained stable, bowel habits improved, and findings were exploratory due to the small, open-label design.

Intermittent fasting edges daily calorie cuts for blood pressure and long-term cardiovascular risk estimates

In a real-world registry study of adults with overweight or obesity, 5:2 intermittent fasting and daily calorie restriction both improved blood pressure over 12 weeks. Intermittent fasting produced modestly greater reductions in systolic and pulse pressure and a larger drop in BMI-based 30-year cardiovascular risk scores, without superior lipid or glycaemic effects.

Filtered coffee shows a causal link to healthier HbA1c levels

Genetically predicted filtered coffee consumption is causally associated with lower HbA1c levels, while other coffee preparation methods show no such benefit. This effect appears to be partly mediated by increases in propionate producing gut bacteria, particularly Veillonella.

Early warning for diabetes: AI model identifies prediabetes risk with high accuracy

A Scientific Reports study developed a pattern neural network that integrates total antioxidant status with clinical and metabolic markers to predict prediabetes in Indian adults. The model achieved very high accuracy and highlighted oxidative stress and waist circumference as key predictors, supporting earlier detection before progression to type 2 diabetes.

Semaglutide helps older adults lose weight without immediate bone loss

Semaglutide shows potential for weight loss in older adults without harming bone density, but longer studies are essential to assess its effects on bone health.

Ultra-processed foods linked to rise in prediabetes risk

The study reveals that ultra-processed foods heighten prediabetes risk in young adults with obesity history, stressing the importance of healthy eating habits.
