Metformin fails to improve insulin resistance in type 1 diabetes

Metformin treatment in type 1 diabetes lowers insulin dosage but does not improve insulin resistance, highlighting its complex role in diabetes management.

Study reveals metabolic benefits of reducing ultra-processed foods in older adults

A controlled feeding study out of South Dakota State University shows that older adults who ate fewer ultra-processed foods naturally consumed fewer calories, lost weight and abdominal fat, and showed improvements in insulin, nutrient-sensing hormones, and inflammation.

Study finds GLP-1 drugs improve strength and reverse aging biology in mice

Researchers showed that GLP-1 receptor agonism counteracts aging across multiple organs in mice, improving strength and reversing molecular aging signatures without meaningful effects on body weight. These benefits depended largely on hypothalamic GLP-1R signaling and closely mirrored the anti-aging patterns produced by rapamycin.

Ultraprocessed diets affect teens and young adults differently

A study reveals that adolescents consume more calories on ultraprocessed diets, highlighting a critical vulnerability in modern food environments.

Oral GLP-1 pill shows strong weight loss and blood sugar benefits in adults with diabetes

A new oral GLP-1 medication can help adults with obesity and Type 2 diabetes lose more weight and improve their blood sugar levels compared to a placebo, according to findings from the ATTAIN-2 trial led by a UTHealth Houston researcher.

Researchers identify the key habits that help adults eat more slowly

Eating slowly and chewing well in Japanese adults were strongly associated with savoring food and avoiding eating with a full mouth, with oral health playing an important supporting role. These behaviours varied across age and gender groups, highlighting cultural eating practices and dental factors that shape how people eat across adulthood.

Trial investigates how quickly human milk responds to common plant based meat swaps

Replacing beef with a plant based beef substitute for six days changed the fatty acid composition of human milk, increasing medium chain saturated fats and lowering key long chain polyunsaturated fats such as arachidonic acid. These biochemical shifts occurred without changes in maternal weight, appetite, glucose patterns or infant milk intake.

Tirzepatide reveals a brain signal that predicts returning food preoccupation

Researchers implanted electrodes in the human nucleus accumbens to track brain activity during severe food preoccupation in an individual taking tirzepatide. They found that a delta–theta biomarker disappeared during symptom-free periods and re-emerged weeks before relapse, suggesting a possible neural marker of vulnerability to dysregulated eating.

Preparing for the respiratory virus season: A guide for families

As respiratory virus season begins, pediatric experts are preparing for an expected rise in cases of Respiratory Syncytial Virus (RSV), which can cause cold-like symptoms in most people but serious illness in infants and older adults.

Understanding leptin's dual function in MAFLD pathogenesis

Metabolic dysfunction-associated fatty liver disease (MAFLD) has emerged as a predominant chronic liver condition globally, intricately linked with obesity, type 2 diabetes (T2DM), and metabolic syndrome.

High protein breakfasts help you feel fuller but do not change how much you eat later

High protein breakfasts, whether plant or animal-based, boosted GLP-1 and PYY and modestly reduced appetite compared with a low protein, high carbohydrate meal. Despite these hormonal and appetite changes, lunchtime energy intake remained unchanged in both younger and older adults.

Off-label GLP-1 use highlights the cultural pressures driving body anxieties

New obesity drugs that were designed to treat diabetes and obesity are increasingly being used off-label by people without these conditions to achieve slimness and social approval rather than health gains. This perspective maps how such pharmacological thinness interacts with stigma, beauty ideals, digital culture, and inequality, and calls for multinational, intersectional research to understand its full impact.

Do GLP-1 drugs cause cancer? New review says no, may even protect

A comprehensive review in The Journal of Clinical Investigation finds no overall link between GLP-1 receptor agonists and increased cancer risk, countering early safety concerns. Instead, evidence suggests possible protective effects for certain cancers, supported by metabolic and immune-modulating mechanisms.

Body temperature and offspring size influence brain size in vertebrates

Vertebrates have extremely different brain sizes: even with the same body size, brain size can vary a hundredfold.

Indoor hydroponic gardening boosts wellbeing for cancer patients

Indoor hydroponic gardening - a method of growing plants using nutrient-rich water instead of soil - could help cancer patients develop better mental health, eat a healthier diet and enjoy a better overall quality of life.

Skipping breakfast has little impact on mental performance, research shows

Skipping breakfast or practicing intermittent fasting is unlikely to cloud most adults' thinking in the short term, according to research published by the American Psychological Association.

Healthy lifestyle habits plus GLP-1 RA drugs can improve heart health of people with Type 2 diabetes

People with Type 2 diabetes who combined healthy lifestyle habits with GLP-1 receptor agonist (GLP-1 RA) medications had a greater reduction in risk of major adverse cardiovascular events, including heart attack, stroke or cardiovascular disease death, compared to people only taking the medication, according to a preliminary study to be presented at the American Heart Association's Scientific Sessions 2025.

Scientists uncover new obesity genes that reshape understanding of weight and disease risk

Researchers identified five previously unknown genes linked to obesity by analyzing rare protein-truncating variants across six ancestries. The study reveals how rare and common genetic factors combine to influence BMI and related diseases like diabetes and heart failure.

The nation’s largest food aid program is about to see cuts. Here’s what you should know.

The Trump administration's overhaul of the nation's largest food assistance program will cause millions of people to lose benefits, strain state budgets, and pressure the nation's food supply chain, all while likely hindering the goals of the administration's "Make America Healthy Again" platform, according to researchers and former federal officials.
