Q: I am a 19 yrs old girl.My height is 5'3' and my weight is 39.5kgs.I have tried a lot but have not succeded in gaining weight.I am very depressed.Please suggest the exact food that i should have to gain weight.

A: Most importantly, you simply need to eat more. You won't feel hungry, but you'll need to remind yourself to eat anyway. Focus on foods that are healthy yet calorie-rich -- brown rice, whole-wheat bread and other whole grains, sweet potatoes, bananas, olive oil, dry-roasted nuts. A good quick snack is whole-wheat bread with natural peanut butter and maybe a piece of fruit -- a couple filling snacks like that throughout the day in addition to what you eat normally will help you start gaining some weight. Good luck!
