Women demonstrated greater sensitivity to this response compared to men, suggesting sex-specific differences in appetite regulation.
Researchers at Rockefeller University identified a three-neuron circuit connecting hunger-signaling hormone to jaw movements of chewing. Inhibiting these BDNF neurons leads animals to consume more food and triggers unnecessary chewing motions, while stimulating them reduces food intake and stops chewing motions.

The use of GLP-1 receptor agonists (GLP-1RAs) and SGLT2 inhibitors in people with type 1 diabetes has significantly increased between 2010 and 2023. This trend is driven by their benefits in weight management and cardiorenal protection, but caution is advised due to concerns about euglycemic diabetic ketoacidosis.

Across England, nearly half of patients struggle to get appointments with specialist teams for weight loss support and care. Bariatric surgery services are also severely limited, affecting over one in five local health areas. Experts warn that without radical action, obesity prevalence and costs will continue to rise.
A large-scale population analysis confirms tirzepatide's similar gastrointestinal tolerability to other GLP-1 medications without increased risk of diabetic retinopathy, medullary thyroid cancer, or pancreatitis. Researchers analyzed real-world evidence from the FDA adverse event reporting system database and found that tirzepatide has...
