Try the Zone or 40-30-30 diet. It aims to balance blood sugar. (I like "The Formula" by Daoust -- it is easy to follow.) Also supplement with magnesium and vitamin B100 as this diet removes flours, and other starches which have these. Also use cold-water fish (tuna, salmon, etc.) as your protein source. Lastly, consider using curry powder and chromium as they help to increase your glucose tolerance. Hope it helps.
