In people with obesity, a high-dose weekly injection of the diabetes drug semaglutide caused a 15% weight loss and improved other heart-related risk factors.

It prods the pancreas to release insulin when blood sugar rises too high, reduces appetite, and makes people feel full following a meal.

Studies show that people who regularly adhere to the Mediterranean diet lower their risk of cardiovascular disease, many types of cancer, and cognitive decline with age.
