Exercise is crucial, you gotta build up slowly, until where you're sweating like crazy and your workout
is an hour long... you can mix it up, doing diff kinds of activities. The ones where you use your legs is the best, like walking and running. Eat more lean protein and less carbs, fill up with extra water, salads, and eat fresh fruit for snacks. Watch the TV show "Ruby" to help with motivation. If you can afford a trainer, they are worth their weight in gold.
