All I can tell you is just to stay away from refined carbs, ESPECIALLY pure sugar. But don't over-restrict yourself, because you might get really depressed and miserable. I experienced that while I was on a very strict diet. Just DON'T EAT PURE SUGAR. Go low-carb, low-GI, whatever. There are lots of websites that you can use as guides. Try www.wholeapproach.com. Hope this helps.
