Time to Come Out of Hiding

[giantr]

So, don't be too surprised that you're seeing a new face here. I've been around for a while, I've just never posted anything because I never really had much to post. But now I am very much in need of your guys' help, because I'm clueless. I may appreciate the male body very much, and I know the basics of bodybuilding, but now that I've had a personal trainer for a while and I'm going to be on my own doing this, I could use some help if you guys are willing, as I said.

So, really my main question centers around dieting. I'm 6'4" and 250 lbs (lol, don't get excited -- 20% body fat). I came down from 270 since two months ago on a diet I'm going to illustrate in a second, but I've been eating basically the same things, and while I am essentially a creature of habit, I was hoping if anybody could tell me some good bodybuilding and fat loss meals. So, yeah, here's what I've been doing:

Breakfast: 2 Large eggs with 1/4 cup of shredded cheese on 2 slices of wheat toast, sometimes 1% milk and sometimes the eggs are just egg whites.

(Insert gym session here)

Post-Workout: 1 scoop of GNC protein powder

Lunch (almost immediately following the post-workout): 1 6 oz Chicken breast, with either a dash of barbeque sauce for dipping or in between 2 slices of wheat with a light spread of olive oil mayo and also a medium-sized baked potato, typically with a bit of ketchup.

Snack: One of the following: 1 Fat free Yoplait yogurt, 3 stalks of celery with peanut butter, 1/4 cup of cottage cheese, a PBJ sandwich (trainer said it was a great snack, and later I learned Jay Cutler does it too), or 1 apple.

Dinner: 1 lb ground beef with either some ketchup or seasoning, 1 20 oz diet Coke

Snack: One of the previously-mentioned snacks.

So, is that doing good? Keep in mind my goal here is to lose fat but put on muscle. Any sort of advice would be much appreciated.
