How to gain weight (teen, high metabolism) without going to the gym?

Hi, I'm 15. I'm 170 cm tall (67 in?) and weigh 52 kg (112 lbs). I know I'm too skinny and I do eat a lot, but I just can't gain weight. I have dance training twice a week (an hour each time) and we run, stretch, do sit ups, etc etc. Now, I'm wondering how to work out (at home, without any equipment if possible) without losing weight? I want to gain weight in my arms and calves especially, and I'd like to tone my butt a lot also. I'm also wondering if someone could maybe write me a 'weight gaining' diet plan? Like, breakfast, lunch, snack, dinner thing. Because I really don't know what more to eat to gain weight! I'm going in high school and I want to bulk up a bit. Thanks in advance, it means so much to me :)

How to Burn Body Fat and Lose Weight

Recommended Answer:

To gain weight you need to combine protein foods with starchy carbohydrates as indicated below. Good weight gaining combinations are bread, cereals, pasta, rice, potatoes or sweet potatoes combined with meat, poultry, eggs, cheese, nuts or sea food. Peanut butter sandwiches and cheese sandwiches are good weight gaining combinations. The protein in the above combinations will help to gain extra muscles.
