How many calories should you be eating to build muscle? . I recommend you take you body weight in lbs x15 Or you body weight in kg x 2.2 x15 to get the total amount of calories you should be eating to focus on building muscle mass. . So for someone who’s 200ls, should eat 3000 calories a day. . Make sure to eat 1g protein per lbs (or 2g per kg)body weight to get the protein you need. Divide the rest of the calories between carbs and fat. . If you want to get more, check out my latest YouTube video. . . . #magnusmethod #nutrition #musclebuilding
