To be able to gain some weight, you will need to determine the number of calories needed by your body to gain weight. Secondly, calculate the number of calories that you need to consume per day in order to gain weight. Next, change your eating habits and aim for three large meals and 2 to 3 snacks per day. Finally, drink lots of shakes and milk or juice instead of coffee or tea.
I "like" you just the way you are. Though? gaining weight is easy.. Eat fries, pasta, pizza, doughnuts, candy, and DON'T MOVE! you're already the most beautiful girl ever. you don't need to change anything.
Same problem!! But I'm 15 and 5"3 and 82... What I so is I will eat really big meals because I eat a ton and then for the 1st hour I just sit and watch tv or go on my lap top! Also I try eating fatty foods! Otherwise my weight drops really low!! Good luck!:)
