Here is kind of what I used to do. I would eat 3-4 eggs for breakfast and sometimes a yogurt. During school I would find time to eat a protein bar. For lunch I would have a peanut butter and honey sandwich, a piece of fruit and maybe something else small. I would eat dinner with my family-usually a meat dish, then go to the gym in the evening. Going in the evening kicks up your metabolism for when you sleep. When I wanted to gain a lot of weight I would come home after the gym and eat another 5-8 eggs.Give an example of 4-6 small meals to eat in a day. It's hard enough trying to figure out dinner!!
One thing to watch out for are salads. The healthiest way to have one is lettuce, grilled chicken, and salsa for your dressing. Salad dressing has way too much fat.
