I have tried a low carb diet once before and I felt lethargic and had terrible headaches...I lasted about 3 days. I am a calorie counter, and find that high sugar foods like donuts and cookies also zap my energy level...for me the best is a low calorie diet that doesn't restrict carbs, but the TYPES of carbs I eat-choosing fruits, vegetables, and whole grains such as oatmeal and whole wheat pasta over simple carbs like Pop-Tarts and cookies. My energy level is much higher, and I stay fuller longer, and have had much better success.
