I have a hard time believing people who claim they are eating 4000 clean calories.
I'm a 6'4" typical ectomorph. Fast metabolism, loose weight if I don't stuff my face with food type.
I was around 180lbs when I started really focusing on working out maybe 3 years ago. When people told me to eat a lot - I did, but I didn't really weigh my food or calculate the calories.
Then I broke 200lbs, and got stuck. Weight wasn't moving either way.
Well, I finally started really really calculating my calories. Proper protein / fat / carb split, 6 meals, etc. etc.
I was nowhere near where I should have been. I'm right around 226 right now closing in on the end of a bulking cycle of 12 weeks, and hopefully will get to 230lbs by week 12. I think I'm around 18% bodyfat.
I'm currently taking in around 3600 clean calories. Perhaps 3800 on days I need that extra food or the body just craves for it.
I'm still gaining.
So make sure you really know what you're eating, because I would like to see your 170lbs ass eat a bowl of oatmeal and lowfat cottage cheese the size of your head.
Uhm. So yeah.
