How can I gain weight. I look so skinny . I'm about to be 18 and I just weight 103 pounds. I want to have meat on my body. What should I eat ? And still be healthy .

You should try Dairy products such as Cheese, Yoghurt, and Full Fat Milk. Look for products considered to be healthy that contain high amounts of Saturated Fat.

There is a disadvantage of trying to gain weight, if you get a liking to those fatty foods, it is a drug and you may not be able to stop and may end up going overweight.
