GLP-1 drugs may offer cost-effective treatment for people with knee osteoarthritis and obesity

A new study led by investigators at Mass General Brigham finds that adding novel weight loss GLP-1 drugs semaglutide and tirzepatide to usual care represents a cost-effective treatment strategy for people with knee osteoarthritis and obesity, with tirzepatide providing greater health benefits at lower cost compared to semaglutide.

Daily meal timing influences longevity risk in adults, study reveals

Researchers analysing Aging Cell data from over 33,000 US adults found a U-shaped link between daily eating window length and mortality. Eating for 11–12 hours per day was tied to the lowest risk, while very short (<8h) or long (≥15h) windows raised death risk, especially in older and White participants.

Gestational diabetes poses substantial cognitive dysfunction risks for both mothers and offspring

A new synthesis of global evidence finds that experiencing gestational diabetes during pregnancy is linked with a decline in intellectual function among mothers, and may increase the risk of neurodevelopmental disorders, including autism spectrum disorder and attention-deficit/hyperactivity disorder (ADHD) in children.

Keto diet reduces depression symptoms by 70% in college students

Research indicates a ketogenic diet may serve as an effective adjunct therapy for major depression in college students, improving mood and cognitive abilities.

Genetic study shows dual GIPR/GLP1R action curbs binge alcohol use

Researchers used drug-target Mendelian randomization to test whether genetically proxied activation of GLP1R and GIPR influences alcohol-related behaviors. They found that GIPR, especially when combined with GLP1R, was linked to lower binge and heavy drinking, healthier food preferences, improved liver markers, and reduced coronary artery disease risk.

Ketogenic diets may lower migraine frequency and medication use

This narrative review argues that the migraine brain is hypometabolic, with converging evidence of mitochondrial dysfunction, impaired glucose handling, neuroinflammation, microbiome shifts, and obesity-related pathways. It proposes ketogenic diets as a plausible preventive strategy that may reduce monthly migraine days and medication use, while emphasizing the need for larger, rigorous randomized trials and careful clinical oversight.

Smoking raises the risk of all subtypes of type 2 diabetes

The characteristics of type 2 diabetes vary from patient to patient and it has been proposed that the condition is made up of four subtypes. Now, new research being presented at the annual meeting of the European Association for the Study of Diabetes (EASD) in Vienna, Austria (15-19 September) shows that smoking increases the risk of the condition, regardless of subtype.

Fast food’s grip on American diets weakens as younger adults cut back

About one-third of U.S. adults consumed fast food on a given day between 2021 and 2023, with an average of 11.7% of daily calories coming from it. Intake has declined from 14.1% in 2013–14, driven mainly by reduced consumption among younger adults.

Scientists uncover brain circuit that turns cravings into eating behavior

Researchers found that the bed nucleus of the stria terminalis integrates pleasure signals from central amygdala prodynorphin neurons and hunger signals from agouti-related peptide neurons to drive consumption. Manipulating this bed nucleus of the stria terminalis circuit bidirectionally altered food intake and body weight in mice.
