For the food part,

You need to eat a diet based on whole foods. Daily, you need around 5 cups (yes, cups) of vegetables, 1-2 servings of fruit, 1-2 servings 100% whole grains, 2 servings of dairy (skim milk or nonfat yogurt), and adequate protein (1 lean protein at every meal). You can also have 1 serving of nuts a day (or natural peanut butter). Eat 3 meals a day plus 2 snacks.

Don't eat anything with added sugars or ANY kind of refined flour. Check labels carefully.

And drink as much water as you can stand. And then drink some more.
