Quick answer: Most adults on a GLP-1 need about 80 to 120 g of protein a day while losing weight, or 1.2 to 1.6 g per kg of a healthy reference weight, plus about 30 g of fibre. When appetite is low, split protein across small meals and eat it first. Enter your details to get your daily and per-meal target in the free Weight Easy app.
