It is good to eat some, because eating protein powder after strength training can increase muscles, and protein powder has no calories. Every time you add muscle, muscle can burn fat, and the heat in the human body is mainly generated by muscle. Muscle can convert accumulated fat into energy and send it out. The more muscle mass, the more energy is converted, that is, increasing muscle mass can reduce fat and achieve the effect of slimming. Even people with the same height and weight will look very different because of the different body fat rates. Because muscle is heavier than fat, it looks much slimmer even with the same weight.
