Gut bacteria send direct signals to the brain to stop you from overeating

Researchers have discovered a novel gut-brain sensory circuit in mice where specialized colonic cells sense bacterial flagellin and rapidly suppress feeding via the vagus nerve. This "neurobiotic sense" operates independently of immune pathways, revealing a direct neural mechanism for microbiota-host communication.

What happens to your weight after quitting GLP-1 anti-obesity drugs?

Stopping anti-obesity medications leads to significant weight regain, starting as early as eight weeks and stabilizing by six months. Despite this rebound, most patients maintain some weight loss compared to baseline a year after discontinuation.

Research uncovers a 'neurobiotic sense' that lets the brain respond to gut microbe signals

In a breakthrough that reimagines the way the gut and brain communicate, researchers have uncovered what they call a "neurobiotic sense," a newly identified system that lets the brain respond in real time to signals from microbes living in our gut.

Can one drug do it all? Reviewing the expanding clinical universe of GLP-1 agonists

Landmark trials have shown that GLP-1 receptor agonists, originally developed for diabetes and weight loss, also provide significant benefits for cardiovascular, kidney, liver, joint, and sleep-related diseases. These effects extend beyond weight loss, suggesting anti-inflammatory mechanisms with broad potential for managing chronic diseases.

Cannabis and psychedelics rated most effective for symptom relief by eating disorder patients

A pioneering international survey of people living with eating disorders has found that cannabis and psychedelics, such as 'magic mushrooms' or LSD, were best rated as alleviating symptoms by respondents who self-medicated with the non-prescribed drugs.

Study uncovers a specialized gut-brain pathway for glucose sensing

In a groundbreaking study, a research team at KAIST has uncovered a gut-brain circuit that enables the brain to selectively recognize glucose—beyond simply registering total caloric intake.

Why obesity spikes with wealth: The real culprit is on your plate

Economic development drives higher obesity rates worldwide, but not because people move less. Instead, rising consumption of ultraprocessed foods plays a much bigger role than declining physical activity in the global obesity crisis.

Shared brain circuit drives opposite mating behaviors in male and female mice

In animals with social structures, the drive to reproduce is a complex process; governed by the brain, it's influenced by both internal cues such as hormones and external factors such as interactions with potential mates.

Are food labels failing Australians? Ultra-processed foods spark confusion

Most Australian adults are confused about what ultra-processed foods (UPFs) are and often misidentify them based on packaging cues. The study highlights strong support for better labelling and public education to help consumers make healthier choices.

Tirzepatide tops the charts for blood sugar and weight loss in type 2 diabetes

A large network meta-analysis ranked eight GLP-1 receptor agonists for glycemic, weight, and safety outcomes in adults with type 2 diabetes. Tirzepatide demonstrated the greatest efficacy for glucose control and weight loss, while liraglutide offered the lowest hypoglycemia risk.

Why exercise is key for keeping slim after you quit smoking

Quitting smoking is linked to greater long-term waist circumference gain, but this effect may be due to shared genetics rather than quitting itself. Increased physical activity consistently helped limit waist expansion across all genetic backgrounds.

Are sweeteners really making our children’s diets healthier?

Higher consumption of low-calorie sweetened (LCS) products among UK children was not consistently linked to reduced free sugar intake, and may reflect less healthy overall dietary patterns. Over 11 years, improvements in dietary quality were slowest among those consuming the most LCS products.
