Im extremely disciplined when it comes to diet and training (if not a lot else) so I'm sure I'd be able to adapt to whatever intake demands a cycle would require. typical day goes something like this:
8-9 am - 1 or 2 egg whites or a cup of plain yogurt w/wheat germ, a few pieces of fruit (mostly apples, grapefruit, and kiwis), steel cut oats
11-12 - salad w/avocado, few handfuls of nuts
2-3 - grilled chicken on wheat bread, another handful of nuts, some sort of veg i dont have to cook like carrots or celery
5-6 - a baked yam, fish or chicken, some type of veg (squash, spinach, broccoli...)
8-9pm - anything I have left over from the day, I try to keep it light (I usually have the munchies around this time anyway)
i also follow my workout (whenever i can fit it into my day) with a protein shake.
I've seen the results of a deca only cycle. My friend looked like he was pregnant.
