Genetic variants may help explain who loses more weight and who gets side effects on GLP-1 drugs

A large 23andMe-based GWAS found that common variants in GLP1R and GIPR help explain why some people lose more weight or experience more nausea and vomiting on GLP-1 drugs. The findings suggest genetics may eventually help predict who responds best to semaglutide or tirzepatide and who is more likely to develop side effects.

Swapping passive screen time with mental activity may cut dementia risk

Research shows that mentally active sedentary behavior can reduce dementia risk, emphasizing the importance of daily cognitive engagement for brain health.

Long-term excess weight is a stronger predictor of cardiovascular risk

Obesity is a known risk factor for cardiovascular disease, but people's weights can shift over time, and little is known about the cumulative impact of excess weight.

Metformin boosts an exercise-linked metabolite and may help control weight in prostate cancer patients

Metformin raised the exercise-linked metabolite Lac-Phe in prostate cancer patients across disease stages and treatment settings, while Lac-Phe itself did not predict anticancer response. Patients in the BIMET-1 metformin arm also showed better weight management during anti-androgen therapy, highlighting a possible metabolic benefit relevant to prostate cancer care.

New obesity definition could delay treatment and widen health gaps

The Lancet obesity framework aims to improve risk assessment but risks delaying treatment and deepening health inequities, according to recent evaluations.

Large-scale exposome research shows how multiple factors influence disease risk

For decades, scientists have been carefully unraveling the role of genes in disease by examining how small variations in a person's genetic code can shape lifelong risk of developing common conditions such as cancer, diabetes, or heart disease.

Irregular bedtimes double heart risk for those getting below 8 hours

Irregular sleep timing significantly impacts heart health, with inconsistent bedtimes linked to a higher risk of major cardiovascular events over a decade.

Low birthweight increases stroke risk independent of adult BMI

In new research to be presented at this year's European Congress on Obesity (ECO2026) in Istanbul, Turkey (12-15 May), researchers show an increased risk of stroke in young adulthood for children of low birthweight, independent of their body mass index (BMI) as young adults or gestational age at birth.

Living near Salton Sea linked to reduced lung growth in children

Children who live within 11 kilometers of the Salton Sea, a drying body of water with a high concentration of salts and contaminants in Imperial Valley, California, have slower lung function growth between ages 10 and 12 than children who live farther away.

Semaglutide for weight loss was linked to a sharp drop in alcohol use in this case report

A 2026 case report describes a 34-year-old man with obesity and alcohol use disorder whose semaglutide treatment for weight loss was associated with a marked drop in drinking over 10 months, with his AUDIT score falling from 27 to 7 and alcohol use dropping from about 15 drinks per week to half a beer per month. The authors frame this as a promising but preliminary finding that adds to growing evidence on GLP-1 drugs and alcohol use, while also stressing that this was a single case and that better AUD screening in family medicine remains important.

Moderate wine intake tied to slower biological aging in men

Researchers studying 22,495 adults in Southern Italy found that men with moderate wine intake in the traditional Mediterranean diet range showed slightly slower biomarker-based biological aging, with the lowest estimated aging signal at about 170 mL per day. The study also found that overall ethanol intake did not show the same moderate-level pattern, and higher total alcohol intake was linked to faster biological aging in dose-response analyses.

Obesity, sleep, smoking, and inactivity show the strongest links to hypertension in U.S. adults

A cross-sectional analysis of 20,912 U.S. adults found that obesity, overweight, inadequate physical activity, smoking, and short or long sleep were each associated with higher odds of hypertension, while overall diet quality by HEI-2015 was not significantly associated. Sleep associations differed by sex, and lower sodium intake remained linked to lower odds of hypertension in sensitivity analyses.

Antibiotic use before and during pregnancy linked to psychological distress

Perinatal depression, which occurs during pregnancy or in the period after childbirth, is one of the most common mental health conditions experienced by women.

Imaging study measures pancreatic fat in children and teens

Higher fat content in the pancreas of children and adolescents with obesity is associated with an increased level of heart and metabolic risk factors, including higher than average body mass index (BMI), elevated diastolic blood pressure, higher levels of abdominal and liver fat, and insulin resistance, according to new research presented at this year's European Congress on Obesity (ECO) in Istanbul, Turkey (12-15 May).

How vitamin D in the first 1,000 days may shape lifelong health

This narrative review argues that vitamin D is clearly important for skeletal health during the first 1,000 days of life and may also shape immune, metabolic, and selected neurodevelopmental pathways during early development. However, the authors stress that human evidence for most non-skeletal outcomes remains heterogeneous, with benefits appearing most consistent in populations with baseline deficiency.

What happens when more of your exercise is vigorous instead of moderate?

In a large UK Biobank analysis, a higher proportion of vigorous physical activity relative to total activity volume was associated with lower risks of eight major chronic diseases and all-cause mortality, even after accounting for overall activity volume. Device-based data suggested that activity intensity generally offered greater preventive potential than total volume alone across most outcomes.

Lifestyle care in primary clinics allows for safe diabetes deprescribing

A new research study provides real-world evidence that deprescribing glucose‑lowering medications is both feasible and safe when patients with type 2 diabetes receive lifestyle‑informed care in primary care settings.

How do diet, smoking, alcohol, and stress reshape the female microbiome?

This review examines how modifiable lifestyle and environmental factors shape the female vaginal, gut, oral, and skin microbiomes, with diet, alcohol, smoking, obesity, stress, hygiene, physical activity, and sexual behaviours all linked to site-specific microbial shifts. It argues that understanding these patterns could help guide future female-focused prevention and intervention strategies.

Digoxin found safe to use in young patients with rheumatic heart disease

Patients with rheumatic heart disease who took the heart failure drug digoxin were 18% less likely to die or experience new-onset or worsening heart failure during a two-year follow-up compared with those who received a placebo, according to a study presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Higher sugar intake raises gallstone risk in adults, study finds

A cross-sectional NHANES study of 8,975 U.S. adults found that higher total dietary sugar intake was associated with higher odds of gallstones, with each 100 g/day increase linked to a 41% rise after full adjustment. The findings suggest sugar intake may be a modifiable gallstone risk factor, but the study relied on self-reported gallstones and cannot establish causation.
