@Alexander99 said in Is Caloric Deficit Peaty?:
My point in the above post was more that you should have a calorie deficit when losing weight, but this is one, albeit an important one, of many factors in losing fat.
The trouble with the idea of a "calorie deficit" is just how exactly do you figure out what that means for you? If you have dieted using calorie deficits in the past, your body can reset its metabolic rate so that you can withstand calorie deficit (=starvation/deprivation) better which means you would need to reduce the calories even further to get any weight loss. This also opens the way to lose muscle mass (from higher cortisol) instead of losing fat.
