Sorry if this is a repeat (I am fairly new and did not see it anywhere.) See research - link - below
Daily Calories: 18 (novice weight lifters) to 22.7 (highly trained weight lifters) calories per pound of body weight.
Daily Protein: .36 (novice weightlifters and overall adults) to .48 or slightly more (advanced body builders) grams per pound of body weight.
The protein calculations were based on nitrogen balance, where even advanced body builders (4 out of 6) stayed in positive nitrogen balance at 1.05 protein grams per kilograms of body weight (.48 grams to pound.)
