I'm looking to do something along the lines of a progressive gain. I'm 6'3 and weigh 158. I've tried exercising for a while, but I'm not seeing much of a change. I figured I must be eating wrong. After talking with someone at a local nutrition/health food store, we came up with this. Most of it was his suggestions, with a few of my ideas. Since I'm not really sure how good it is, I'd like a few opinions on it. If anyone has some criticism and wants to suggest some changes, feel free to. Also, it would help if someone could recommend what times of the day I should be eating at.

Breakfast:
Bagel or oatmeal
Eggs
Orange juics
Multi-Vitamin

In-Between:
Protein bar - Powerbar Protein Plus?

Lunch:
Tuna or turkey sandwhich (wheat bread)
Fruit

In-Between:
Protein bar

Dinner:
Chicken breast
Rice (brown) or potatoes
Vegetables
Multi-vitamin

Alternatives to the above:
Fish
Red meat (lean)
Salad

Between dinner and bread:
Cottage cheese or yogurt.

it really depends on you and what you're doing exercise wise, if you're lifting a lot you need lots of protein etc, also you don't post weights or amounts, even eating too much of good things can take you in the wrong direction.

You should probably try to look up all the things you're eating to get your actual intake values then post them, people should be able to help you a lot more then.

As for when you eat, it doesn't matter as long as you're spreading your meals out. it's a good idea not to eat before or after a work out, but again that depends a lot on your goals, are you willing to sacrifice some muscle gain for more fat loss? if you don't eat after a session you'll burn more fat, but it'll also cost you some of your muscle gains.

Apart from that about the only other recomendation i can give is to avoid eating a lot of carbs close to when you're going to sleep, becuase you won't use them and they'll get stored.

Roughly 1700 calories. I'll have to look up the other details and post them later.

I don't have any fat to lose. Muscle gain is what I want.

edit: As for exercises I'm doing, they're pretty basic.
"on" day: 30 pushups, 30 situps, 15 crunches, 3 sets of 10 "bench press" reps on a total gym, 2 sets of 10 dumbell pullovers on the total gym, 6 chinups, 5 hanging leg raises
"off" day: 1.5 mile walk (it's winter, so I can't run) and about 20 minutes of aerobic activity.

I usually work out every day excluding sunday.
