Rissie,

I dropped some wieght by:

A. Finding the hidden sugar in the foods I was eating--check the labels for the carbs--you might be surprised where and how much you find.

B: I either cut the high carb foods completley (i.e. no McDondalds fries!!) or substituted low carb foods for them

C: Started a simple excersize routine

Don't expect overnight results-the main thing is to find something that works for you and stick to it.

You should start seeing some results in a few weeks---Don't overdo it though, talk to you parents and check some of the links offered up in the other replies. There's tons of info out there that will help you do it properly.

Best of luck
