How it fits into a meal

For building muscle, Schoenfeld and Aragon's 2018 review of the research suggests about 0.4 g of protein per kilogram of body weight at each meal, spread over at least four meals a day. At 170 lb (77 kg), that's about 31 g a meal. A medium baked potato with the skin covers about 14% of that.
