If he trains (trained?
) MMA 4-5 times a week I don't think he needs to add another 1000kcal to his diet
I'm 5'10-5'11 (178cm) and abit under 80kg (under 180lbs). I consume 2100-2200kcal without working out. I consume 800-900kcal on average in training => 3000kcal approx per day. Plus that I have a cheatday once a week, when I problably go up to 4000kcal with less smart food. So I think I'm in good balance. My weight does fluctuate alittle between 175 and 180 depending on many things.
800-900kcal is the average of weightlifting, bjj, mma and kickboxing. I train 5-6 times/week MA and twice weights. When lifting weight I only consume 300kcal. MA everything from 700-1200 kcal. Added with the cheat day I think I personally have found a good balance.
