How many calories will a weightlifter need per day?

It takes 5,000 Calories to maintain your body weight, when bulking, counting the working out you do, so you still burn a little calories, but the majority stores, and you eventually burn the fat out and stack mucle, especially with whey protein, or Iso protein. also include 1.5Xyour body weight in protein,

I.E: A 150 Lb boy should get 200 Grams protein every 48 hours, minimal. Helps this helps, lol.
