You know, based on the trends I see with this board, most of the men on here are really "organic bodybuilders".
That's a fine thing to be and all, but it's laughable at how "process-phobic" members on here are. Not everything is bad for you if it didn't come straight out of an unfarmed grass, root or tree. Geeze, lol. It's funny how judgmental every one is about foods in general. You guys are acting like every single non-organic food is harmful. Spend your energy on building discipline in your routine and macro-nutrient intake instead of nitpicking margarine. Besides, the only negative drawback to have on margarine was its trans-fats, which can now be avoided altogether.
Just focus on working out and doing cardio. Those two, coupled with adequate micro-nutrients, will keep you as healthy as you can be. Genetics will play itself out either way. There is no stopping it.
