They suppress your appetite so you never feel hungry
FALSE “GLP-1 medications mimic Glucagon-like peptide-1 – one of the hormones involved in appetite regulation. It doesn’t completely suppress hunger, but it is powerful,” says Dr Federica Amati, nutrition lead at Imperial College School of Medicine and author of The Appetite Reset. “The medicine is about 1,000 times stronger than what we naturally produce from our gut,” she explains. As food passes through the gut, cells called L-cells sense the nutrients, which sparks the production of the GLP-1 hormone. Without the drugs, these bursts of GLP-1 production last a few minutes. “It’s a bit like a sparkler. In comparison, the drugs are like a bonfire that roars for a week,” says Amati. Because the GLP-1 hormone stays in your body for longer if you are on the drugs, you feel fuller faster and your appetite gets suppressed, but you will eventually get hungry.
