I am 20 years old.I am looking lean, but I am totlly become a good height and becme a fat, fitness.

I'm not sure what you are asking. You want to make yourself taller? That's pretty much impossible.

If you want to gain muscle and weight you will have to change your eating and exercise habits.

Why would you want to get fat? Your body right now at age 20 is still in the process of "finishing" itself and will eventually fill out. Lots of people have slender builds and as they get older tend to put on weight until they reach their peak weight. You are trying to rush things right now. Won't work. Sure you can eat a bunch of junk food and gain weight but you don't want all that starch weight on your body. If I could only go back to age 20... ah... I had such a lovely thin build on my petite frame. Then I got old... and now I'm stuck with excessive baggage that I can't seem to shed. Be happy with the body you have now and keep adding muscle and some weight as you get older... only do it gradually.

Hi, ramraj0002!

Are you a man or a woman, please?

Thanks!
