Is this what i should eat to maintain weight?

Don't fall for all of the diet/health food companies crap. As long as you are matching your caloric intake to your excersise you should be fine. And watch protein, it helps build muscle which burns fat. Stay away from sugary foods. I read that an average adults sugar intake per day is 40 grams tops. I try to stay under that but naturally sweet foods like fruit are ok and don't count as much. My one sugar food during the day is a couple cups of coffee. The best thing to do is go to a nutritionist who can better explain these to you and customize a diet for you based on age weight height. There is no one perfect diet. But staying active and eating right changes everything. Too many times have I watched people try diets because Of some book or their friends are doing it only to never exercise. And people who exercise but don't eat right. You talk about wanting a bigger , that's really based on how you work out that part of your body and genes. If you don't want to pay for a nutritionst try going to a local gym and talking to people about their diets then you can get a general idea. Just don't starve your body, that can be as bad as overeating because your body doesn't know when it is going to eat next so it stores all of your food as fat. Check out protein shakes with less calories and more protein. Chicken is a good start too since it almost has as much protein as a steak but a lot less fat and calories. Also don't forget to watch out for creatine supplements, it could be in protein shakes. It does help in building muscle but makes you gain water weight. And NO gatorade, people drink that stuff all the time but is only meant for intense exercise to replenish sugars and electrolytes which is basically a fancy word for salt. That means fat and water weight. If you need any more help just ask.
