Truck Lewis: As for eating right, I just stopped eating like an idiot: Pizza, fried chicken, french fries, Spaghettios, ice cream, Mac & Cheese, chips, a bunch of American cheese... all that junk. I'm not saying that I'll never eat those things again, just not very often.
I've substituted all of those bad, fatty foods with apples, carrots, peaches, pineapples, bananas, light yogurt, etc. As for the base of my meals, I have been eating a lot of Thin N' Trim chicken and turkey breast (sliced from the deli). Some tomato soup here and there. Cereal for breakfast every once in a while. Instead of having two pieces of bread for a sandwich, I'll have one.
What do I drink? Absolutely nothing but water and iced tea (with Splenda). The only other thing I have had in the last 3.5 weeks is beer, and I only had one, so it hardly counts.
I have also been closely paying attention to the nutrition facts on everything I eat.
I've cut down my late-night eating severely, and if I do find my stomach rumbling at midnight or later, I'll have some baby carrots or whatnot with a bottle of water.
I have also found that gum and water cures a lot of the "I'm not really hungry but I want to eat something because I'm bored" urges.
Exercise: for the first two weeks I jogged a mile like every other day. Then I started adding in push-ups and crunches every now and then. And of course, being a basketball addict like myself, I have played lots of basketball. If I wasn't involved in a competitive pickup game, I've done drills from my old AAU coach that keep me working (as opposed to just casually shooting around by myself).
I might even add light weight lifting some time soon, but I've got to learn a little more about it before I jump into it.
In all honesty, it's not that hard. Not as hard as it sounds, anyway. Even if you're active for 15-30 minutes a day, it's going to make a difference.
