Semaglutide outperforms other GLP-1 drugs for weight loss in psychiatric populations

A network meta-analysis of nine randomized controlled trials found that once-weekly semaglutide showed the largest estimated weight-loss effect among GLP-1 receptor agonists tested in adults with mental illness and obesity or related metabolic risk. The authors cautioned that the findings remain preliminary because the evidence base was small, heterogeneous, and largely indirect.

Meat and dairy cuts may improve health without raising food costs

A Scottish microsimulation study found that reducing meat and dairy intake, especially red meat among high consumers, could improve modeled health and environmental outcomes without increasing diet costs. However, some nutrient intakes, particularly calcium and iodine, declined, highlighting the need for carefully planned substitutions and fortified alternatives.

GLP-1 medications may improve long-term health for people with peripheral artery disease

GLP-1 receptor agonists (GLP-1 RA) medications were shown to reduce the number of deaths, amputations and hospitalizations among people with Type 2 diabetes who also had narrowed leg arteries associated with PAD (peripheral artery disease), according to new, independent research published today in the Journal of the American Heart Association, an open-access, peer-reviewed journal of the American Heart Association.

Study links semaglutide and tirzepatide to fewer anxiety and depression diagnoses in obesity care

A US electronic health record study found that adults with obesity who started semaglutide or tirzepatide had lower recorded hazards of anxiety and depression than matched patients using naltrexone-bupropion. However, among adults without type 2 diabetes, tirzepatide was linked to higher recorded hazards of anxiety and insomnia than semaglutide, underscoring the need for cautious monitoring.

Experts reframe steatotic liver disease as a dynamic continuum

The classification of steatotic liver disease (SLD) is undergoing a major conceptual transformation. In a recent article published in eGastroenterology, Dr. Chen, Dr. Horn, and Prof. Tacke from Charité - Universitätsmedizin Berlin argue that metabolic dysfunction-associated steatotic liver disease (MASLD), metabolic dysfunction and alcohol-associated liver disease (MetALD), and alcohol-associated liver disease (ALD) should not be regarded as rigid diagnostic categories, but rather as interconnected and evolving disease trajectories.
