How much protein should you eat on Mounjaro?

Most guidelines recommend 1.2–2.0g of protein per kg of body weight during weight loss, depending on activity level. Higher protein intake helps preserve muscle mass, which is especially important when appetite is reduced.

What happens if you do not eat enough protein?

Insufficient protein during weight loss can lead to muscle loss, fatigue, hair thinning, and a slower metabolism. Prioritising protein at every meal helps maintain lean body mass.

What are the best sources of protein?

Lean meats (chicken, turkey), fish, eggs, Greek yoghurt, cottage cheese, lentils, beans, tofu, and protein-rich dairy are all excellent sources. Aim for a variety across the day.
