How many grams is a function of how big you are and your genetics. AND, you don't need to feed the fat. What works for most people is .80 - 1.2 grams of protein per pound of
Lean Body Mass (LBM).
Find out how much
body fat you have percentagewise (or guesstimate).
Multiply that by your body weight. This will tell you how many pound of fat you are carrying.
Subtract that number from your body weight and now you have your LBM.
LBM * 1.0 will be how many grams per day you need to consume (and don't try to do it in one meal - spread it out evenly throughout the day).
Most people do fine with 1.0 but you will have to experiment. If you just use the 1.2 times the bodyweight you will be intaking more than necessary (anything to an excess will be stored as bodyfat)
A
good ballpark of how many
calories is bodyweight times 10 for cutting, times 12 for building.
