Watching calories is a myth. Fact is, not all calories are the same. Cut the fat to the minimum for a proper diet.
Hardly.
If he's trying to gain muscle/mass, cutting the fat to a minimum is the wrong philosophy. Most people bulking go for a 50/30/20 split of carbs, fat and protein.
I target 3500 calories daily, meaning I have a goal of 375g carbs, 100g of fat and 151g of protein. With this (and my workout routine), I can put on rougly half kg of mass a week.
TDEE is 2,299
i've used myfitnesspal and this other one called fooducate, they're very useful to me.
Yep so aim for 2800. If you have trouble with eating that much, try to slowly increase it up to 2800. Liquid meals also help a lot.
