Get it thru your head that you need to eat your ass off. No special written diets no weighing of food just eating till you are full and then a little more. No damn oats, no low fat. I would eat lots of triple cheese burgers, chilli, big ass burritos if I was you, pasta, potatos, more beef.
I bet you were a "picky eater" as a kid. 4 days a week of training should be plenty, big basic excersises. An NO cardio!! its the last thing you need. After you put on 50 lbs then we will start to consider the cardio again.
Im also guessing Lugar that you suffer from high anxiety, this will burn calories like you would not believe. Relax! I can feel the anxitey in your writing. Eat more train less! You see THIS IS THE WAY you seek. You just have to able to accept it.
Please do not post another diet. And no crying about loss of definition, do you thing concentration camp lean is a good look? Cause it sounds like thats where you are now. If you wanna change that then heed the advice.
