The promise is gigantic: one injection per week and the pounds should fall away. What's more: the new weight loss aids could also reduce the risk of heart attacks and strokes. Semaglutide is the name of the enabler that is found in medications like Ozempic or Wegovy. The active ingredient mimics a hormone from the intestine called GLP-1. The hormone not only regulates insulin secretion and gastric emptying, but also appetite.

Since then, the physiologist has been considered one of the midwives of the weight loss aids that the whole world is talking about and which are currently bringing record sales to the Danish pharmaceutical company Novo Nordisk.
