Yes,and I don`t agree with it.......I agree with the calorie deficit part,but clean bodybuilding foods make a huge difference in your physique.
On a sidenote,the lack of a fucking quote function sux!!! 
Why the hell can't you and some others qoute? It makes following what you're saying tough.
I agree with you. I think maybe there's more of an ability to let a calorie be a calorie when you're TA's age at the time he went off about that. I think most of us over 30 have learned that does not stay true. (Being on a ton of gear would except that)
Anyway, to me it only makes sense that when you are hitting weights, cardio, and diet to lean out that a gram of protein outweighs the value of a gram of a simple sugar carb. Personally, I used to eat a grilled stuft steak burrito and a steak gordita from TB every single day on top of my other meals and I had abs. I continued that past 31-32 and ended up with an ab. Trying now to get back to my normal look, and it hasn't been ez at all
