For mesomorphs maybe. For endpmorphic types it is damn near the hardest thing in the world.
The rate of change may vary from individual to individual, but you only need to do the principles. An endomorph may have to be somewhat more disciplined and expect a slower rate of change, but it’s the same process for everybody.
The way a bodybuilder will burn fat, aside from exercise, is he will his calorie content until he is losing a pound every week. However, to keep his muscle from being metabolized, he will prioritize his calories away from carbohydrates and focus of protein and fat.
I’m not suggesting to lose a pound/week. Set yourself to lose it every two weeks or three weeks or a month. As long as you are doing it consistently and as part of a lifestyle.
I will say, just so you are aware, that when bodybuilders are cutting that they are as miserable as anybody else who has to diet. They can’t eat until they are full and they can’t eat the foods they like when they are cutting.
It isn’t just those who need to diet for weight control that are miserable.
