I would love to look like that. and how do they do that thing with their hair where they have their bands side swept. how do you do that? ok sorry im rambling. thanks for the help!

if your fat, your fat

stop trying to be something you're not.

im not fat, and im not being something im not, its just a question.

airbrushing and hairspray

Just search under MyPyramid for a diet just right for you. They actually take the information you give them (age, gender, weight, etc) and within seconds form a printable diet that is completely safe and healthy for you.
Exercise of course is nesseccary no matter what diet you're on. Stretching, aerobics, and weight bearing exercises are the three basics. Try a sport or yoga.
Good luck!
