What factors affect an increase in calories in a person other than activity level, stress, etc…if ANY?? Here’s what I mean - A co-worker of mine, is around 5’8" and 145lbs - very lean and low bf. He used to eat like shit, only 2 meals a day (lunch and dinner and the occasional snack). He started to eat very ‘clean’ and work out in order to bulk up, he has up’d his calories accordingly (~3500 - 3800 kcal per day).
He admits that he has trouble hitting this EVERY day, but based on his food log, I would say he consistently hits 2500-2800 kcal per day. Now, if he used to only eat, let’s say 1500-1800 (between lunch and dinner) before he started to eat clean and more calories and never LOST weight, how come he has only added a few lbs over the last few months since he has INCREASED his calories quite a bit.
I know there is no “exact” equation that says, up your calories by x and you will gain y (I know you can kind of figure this out), but I guess my question is what factors affect a persons ability to add mass. Can another person increase calories by 1000-1500 like this guy is doing and add more than a few lbs?? Does your body hit a point where it CAN’T loose anymore weight - Like when he ate like shit and was only consuming 1500-1800 kcal’s a day??
In terms of macro’s, he’s set with a good breakdown of P/F/C…
Not sure if this makes sense - if not, just blacklist me from T-Nation.
