Early obesity treatment reduces long-term health risks for all children

Children living with obesity but showing no signs of metabolic complications still have a significantly increased risk of developing type 2 diabetes, high blood pressure, and abnormal blood lipid levels later in life.

Firmer potatoes lower post-meal blood sugar spikes

Minimally cooked potatoes may reduce blood sugar spikes, but benefits are short-lived and specific to certain populations, as shown in recent research.

Replacing sedentary time improves insulin resistance in adolescents

Adolescents who replaced just half an hour of sedentary behaviors, such as sitting on the couch or spending time at the computer, each day for moderate-to-vigorous physical activity or sleep may lower their insulin resistance, a key factor in preventing the development of Type 2 diabetes, according to preliminary research presented at the American Heart Association's EPI|Lifestyle Scientific Sessions 2026.

Oral semaglutide fails to slow early Alzheimer’s decline in two phase 3 trials

Two large phase 3 trials found that oral semaglutide 14 mg did not slow cognitive or functional decline over 104 weeks in people with early symptomatic, amyloid-positive Alzheimer’s disease. Semaglutide was generally consistent with its known safety profile and showed some biomarker changes, but these did not translate into clinical benefit.

GLP-1 drugs cut heart and kidney risks in type 1 diabetes study

In a large target trial emulation of 174,678 people with type 1 diabetes, GLP-1 receptor agonist initiation was associated with lower risks of major cardiovascular events and end-stage kidney disease over five years. The study also found no increased risk of hospitalization for diabetic ketoacidosis or severe hypoglycemia, supporting further randomized trials of GLP-1RAs as adjunctive therapy in type 1 diabetes.

AI diet plans underestimate teen nutrition and miss key nutrients

AI tools for adolescent diet planning may fall short, consistently underestimating nutrient intake and energy needs compared to individualized dietitian plans.

Mandated caps reduce insulin out-of-pocket costs among US Medicare beneficiaries

A new analysis led by researchers at the Johns Hopkins Bloomberg School of Public Health finds that out-of-pockets caps on insulin for Medicare Part D beneficiaries have reined in insulin prices.

How long should you take GLP-1 drugs? Study links longer use to lower heart risk

Continuous use of GLP-1 receptor agonists in adults with type 2 diabetes was associated with a lower risk of major cardiovascular events compared with sulfonylureas, with benefits increasing over time. Discontinuation or interruption was associated with a progressive loss of this protective effect, with risks approaching those of comparator therapy.

Early morning workouts may improve cardiometabolic health

People who regularly exercised early in the morning were significantly less likely to have coronary artery disease, high blood pressure, Type 2 diabetes or obesity compared with people who exercised later in the day, according to a study being presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

People with type 1 diabetes face higher risk of developing dementia

Having type 1 diabetes is associated with a higher risk of developing dementia, according to a study published March 18, 2026, in Neurology®, the medical journal of the American Academy of Neurology.

Stopping GLP-1 treatment linked to increase in risk of major cardiovascular events

Following a rapid increase in popularity of GLP-1 drugs for diabetes and weight loss, such as semaglutide and tirzepatide, approximately one in eight U.S. adults now take these medications, which also provide cardiovascular benefits.

Study finds GLP-1 medicines cut fat while preserving muscle function

Researchers found that GLP-1 medicines caused weight loss mainly through fat reduction, with only modest decreases in absolute muscle mass and no disproportionate loss of muscle function. In mice, physical performance improved, while in a small 12-week human pilot trial, strength was preserved despite reduced thigh muscle size.

More US adolescents are obese but fewer are trying to lose weight

The rising obesity rates in American adolescents, coupled with declining weight-loss efforts, signal urgent needs for targeted public health interventions.

Weight-loss drugs linked to preterm birth risk in women with pre-existing diabetes

Weight loss drugs have been linked to an increased risk of premature births among women who took them inadvertently just before or during early pregnancy to treat pre-existing diabetes.

Tailored prediabetes treatment may better prevent Type 2 diabetes

A one-size-fits-all approach to prediabetes treatment may miss the opportunity to implement an early, more intensive, tailored prevention approach for those with the highest risk of developing Type 2 diabetes, according to preliminary research presented at the American Heart Association's EPI|Lifestyle Scientific Sessions 2026.

MIND diet may protect against structural brain deterioration

The combined Mediterranean and blood pressure lowering diet (MIND) may slow the structural changes related to brain aging, finds research published online in the Journal of Neurology Neurosurgery & Psychiatry.

How one antibiotic dose can reshape your gut microbiome for years

Long-term registry-linked analysis of nearly 15,000 adults shows that antibiotic use is associated with persistent changes in gut microbiome diversity and composition for up to 4–8 years. These effects vary by antibiotic class, with clindamycin, fluoroquinolones, and flucloxacillin showing the strongest and most sustained associations.

Researchers show how smartwatches can help identify insulin resistance

Researchers developed a scalable framework that predicts insulin resistance using wearable-device signals, routine blood biomarkers, and demographic data, with stronger performance when these data streams were combined. The study also introduced an AI agent to explain insulin resistance risk, interpret results, and support earlier metabolic risk screening.

Expert consensus validates UDFF for noninvasive fatty liver assessment

As the global burden of obesity, type 2 diabetes, and metabolic syndrome continues to rise, fatty liver disease has become one of the most prevalent chronic liver conditions worldwide. Its progressive forms, including metabolic dysfunction‐associated steatohepatitis (MASH), cirrhosis, and hepatocellular carcinoma, now represent a major public health challenge.
