Are there any good weight loss sites for teens that aren’t obese?

I’ve tried searching google and everything I find it for obese teens I only want to lose 15 or 20 pounds.
I don’t know any sites. I suggest doing some exercises that get the legs moving, such as walking, jogging, running, swimming or bike riding. These exercises that really get your heart pumping will burn the weight off quickly.

I like push ups, yoga stretches, pull ups, crunches, curl ups, leg stretches, calf raises, and squats as far as being good toning exercises that use no equipment and cost zero money to perform. I like taking some dumbbells and doing some easy bicep curls, military presses, and lateral raises. I think diet is important also and try to eat healthy home-cooked meals with lots of vegetables in them. I try to stay away from the pop and sugar, candy, white flour products, and fast food. I try to get a good night’s sleep each night.
