||Super cut keto Can You Eat Meat? Unlike most women's diets, any good diet plan for men will allow you to eat plenty of meat. Because a man's body has so much more muscle (even if you are out of shape) than a woman's body, you need protein to feed those muscles. Keeping in mind that the more muscle you have, the greater your metabolic rate, you should really focus on both feeding your muscles protein and working out, too. Do You Have to Work Out? With any diet, you never really have to work out, but if you do, not only will you feel better, but you will be burning more calories, putting on muscle, and also raising your resting metabolic rate.
