Food. An easy substance for all of us to abuse. It is much easier (easier not easy) to quit smoking than eat healthy all the time because all you have to do is not pick up a cigarette again. You have to deal with food all day, every day. You can't ignore it.
If my trainer (K) had his way, I would be eating 4 meals a day - all before 7 pm, all protein with good carbs like veges and brown rice. It doesn't happen. At least not 100% of the time. What I do is give it my best shot. I make sure I eat protein with every meal (chicken, eggs, beef tenderloin, turkey, whey, shrimp), try to have a big portion of veges at least once (better twice) of asparagus, cauliflower, peppers, onions, spinach, brussel sprouts - and a smaller portion of some carb. I don't always pick the best carbs, but I don't eat much bread or pasta these days and I lay off the sugar as much as I can. I drink pretty much only water, tea, black coffee and nonfat milk in small portions. K says more important than anything is portion control. Today I had oatmeal with protein powder (whey) for breakfast, a small black bean burrito with salsa for lunch, and I split a big helping of beef fajitas into two meals for supper and dinner. Pretty good day. Then I made cookies. OOPS. Crap. But really, it is WAY better than I used to do, which was eat whatever I wanted whenever I wanted. I didn't care. I didn't care what it did to me; I didn't even care if it killed me. But I have to care. Things changed big time for me, though, and I stopped not caring whether I lived or died. I have a purpose, things do happen for a reason and life is not to be wasted. I don't make eating complicated, I just follow what I said above the best I can. I don't count calories, I don't eat or drink "diet" anything and I don't eat things I don't like. End of story.
