So protein is a big lever, because one, it has a higher thermic effect of food, so you're getting a little bit more calorie burn per day even though it's not a ton because TEF is a pretty small percentage of your overall energy expenditure. But still a benefit. You're getting the effects on lean body mass. If you're in a diet, it's going to help preserve lean body mass, if you're at maintenance, it's going to help build a preserved lean body mass, and if you're in a surplus, it's going to help build a preserved lean body mass. Then you get the effects on appetite.
