Obesity Care Is Moving Beyond GLP-1s Alone

A new peer-reviewed commentary says the next phase of obesity treatment may be more personalized, combining medications with lifestyle support, procedures and better measures of health risk.

A Small Study Links Prebiotic Fiber to Changes in Liver Fat

A four-month human study suggests a specific prebiotic fiber may influence gut metabolites tied to fatty liver, but researchers say larger studies are needed before it can be considered a treatment.

New Obesity Drug Guidance Says Medication Is Only Part of the Plan

A new American College of Physicians guideline recommends semaglutide and tirzepatide as first-line medication options for eligible adults, but says nutrition, physical activity, side effects, access and personal health goals still matter.

Weight Loss Drugs Are Not All the Same, a New Review Suggests

A review of clinical trials found tirzepatide was linked with greater average weight loss than semaglutide or liraglutide in adults without diabetes, but the findings do not mean one medication is right for everyone.

Lifestyle Changes for Prediabetes May Support Health Decades Later

A long-term follow-up of the Diabetes Prevention Program links intensive lifestyle changes to a lower burden of multiple chronic conditions in older age.

Weight Regain May Not Erase Every Metabolic Benefit

A long-term follow-up of two lifestyle trials found that reductions in fat stored around the organs were associated with a lower risk of type 2 diabetes years later, even as average body weight returned to baseline.

Experimental Oral GLP-1 Pill Shows Promise for Diabetes and Weight Loss

A once-daily pill lowered blood sugar and body weight in two phase 2 trials, but larger and longer studies are still needed before it could become an option for patients.

Clearer Menu Warnings May Help Diners Choose Less Added Sugar

A large online study found that people selected restaurant meals with less added sugar when high-sugar items carried noticeable warning labels.

Nutrition Labels May Not Tell the Full Story About Ultraprocessed Food

A new observational study found that health differences remained even after researchers accounted for overall diet quality, but it cannot prove that processing caused them.

Alcohol Raises Cancer Risk Even at Low Levels, Analysis Finds

A global analysis found clear links between alcohol and cancer and liver disease, while the evidence for some heart, metabolic and brain conditions was more complicated.

Tailored Meals Linked to Fewer Hospital Visits, Lower Health Care Costs

A Massachusetts Medicaid analysis suggests home-delivered, dietitian-designed meals may help some high-risk patients avoid costly medical emergencies.

Healthier Meals May Start with Just a Few Food Swaps

A computational study found that one to three food substitutions could improve modeled nutrition quality and lower meal costs, but the approach has not yet been tested with real users.

Are Dairy Trans Fats the Same as Industrial Trans Fats?

A new review found no clear link between naturally occurring dairy trans fats and higher heart disease or type 2 diabetes risk, but the dairy-funded study needs careful context.

A Father’s Metabolic Health May Matter Before Conception

New research points to sperm signals that may help explain how paternal obesity could influence offspring metabolism, but the strongest evidence so far comes from mice.

AI Mouse Atlas Reveals Obesity’s Wider Effects on the Body

A Nature study found obesity-related nerve and immune changes across the bodies of mice, with some matching molecular signals in human tissue.

Healthy Habits May Lower Type 2 Diabetes Risk, Even with Genetic Risk

A large UK Biobank study found that lifestyle patterns were strongly linked to type 2 diabetes risk across genetic risk groups, though the findings should not be read as proof that diabetes is always preventable.

Waist Size and Body Fat May Reveal Health Risks BMI Can Miss

A large UK Biobank study found that combining waist circumference with body fat percentage helped identify people at higher risk for diabetes, heart events and chronic kidney disease, including some whose BMI did not place them in the obesity range.

Does Yo-Yo Dieting Really Ruin Your Metabolism?

An expert analysis argues that repeated weight loss and regain may not cause the lasting metabolic damage many people fear, though weight regain can still reverse some health gains.

Not All Ultraprocessed Foods Are the Same

A new expert panel report says food policies should account for both processing and nutritional quality, rather than treating every packaged food the same way.

Weight Loss Is Not Just About Fat Loss

A conference-presented review suggests obesity drugs and surgery may lead to a higher share of fat-free mass loss than diet and exercise, but the findings are still awaiting full journal peer review.

Red Meat Helped Shape Human Diets. Modern Eating Changed the Equation

A new review traces red meat’s complicated role in human evolution, health and disease, arguing that context matters as much as the food itself.

Type 2 Diabetes May Start with More Than Insulin

New research found that people newly diagnosed with type 2 diabetes had sharply higher post-meal glucagon levels tied closely to fatty liver disease, raising new questions about how early metabolic dysfunction develops.

Weight Loss May Not Lower Diabetes Risk the Same Way for Everyone

A long-term observational study suggests some people may remain at high risk because of underlying metabolic issues, including fatty liver and insulin resistance.

Vitamin D May Lower Diabetes Risk for Some People

A new analysis of a clinical trial found reduced risk only in people with certain gene variations.

Keto Diet May Affect Pancreatic Function in Type 2 Diabetes

A small study found changes in a marker of insulin-producing cell stress, but it did not show diabetes reversal.
