Does consuming less fats equal to body fat reduction?
No.Body fat is also a function of carbs.Carbs stimulate insulin which blocks fat use and promotes conversion of excess glucose into fats.
Body fat goes down when body
So to lose body fat
Lots of variables.
If all else is equal in your diet, then yes because total calories will have decreased. And a caloric deficit is really the only want to guarantee fat loss.
But if calories are being equated by increasing carbs/protein, then probably not, but maybe in the short term just because you’d be storing less fat but I’d assume that’s negligible.
