Experts say success should be measured by changes in things like blood sugar, sleep, mobility and quality of life, not just pounds lost.

A study of African adults found that lean people with type 2 diabetes showed signs of lower insulin production and a different pattern of complications than those with overweight or obesity.

In a small six-month trial, people who limited eating to noon through 8 p.m. improved a key measure of blood sugar control, though they did not lose significantly more weight.
Communities with more dollar stores had higher rates of obesity, high blood pressure and type 2 diabetes, but the study cannot show the stores caused those outcomes.

An international group of experts argues that diabetes prevention should begin long before blood sugar reaches the prediabetes range and continue across different stages of life.
A large observational study found lower hospitalization rates among adults with alcohol-use disorder who started semaglutide or tirzepatide, but it cannot show that the drugs reduced drinking or treated alcohol dependence.
In a randomized trial, medically tailored groceries combined with recipes and nutrition support modestly improved blood sugar control among Medicaid patients.
A new American Heart Association scientific statement finds that moderate caffeinated coffee consumption does not appear to raise cardiovascular risk for most adults, though individual responses and caffeine sources vary.
A phase 2 trial found improvement in liver fibrosis among some patients with MASH, though the main drug combination did not outperform its comparator.
Adults with both obesity and low muscle mass or strength were more likely to develop type 2 diabetes than those with obesity alone.
A large European study found blood-marker patterns linked to higher ultraprocessed food intake, but it does not prove these foods caused the changes.
A modeling study in Scottish adults found that modest swaps away from some meat and dairy could improve diet quality, support public health goals and lower food-related environmental impacts without increasing overall diet costs.
A large observational study found blood pressure and cholesterol gaps have narrowed among older adults with obesity in several high-income countries, likely because of medication use.
A study of healthy 18-year-olds found longer sleep was linked with fewer next-day blood sugar swings, but researchers say diet, activity and daily routines may also play a role.
A new review found signs that nonnutritive sweeteners may affect insulin, blood sugar markers and the gut microbiome, but researchers say the evidence still depends on what they are compared with.
