How can I gain weight but the healthy weight?

Anonymous
I've always been naturally skinny my whole life and I look pretty healthy. It doesn't look like I have an issue or disorder. My Doctor said she would like to See me gain 20 pounds and she even prescribed me something but it didn't work. It took me a couple weeks to gain one pound. I eat a lot but I skip breakfast because I don't have time for it and I Don't work out. I know I should start. Any Advice?
