Is there a fantastic diet weight loss plan for an overweight but healthy person?

No, just a sensible. One. To lose weight insure that calories burned > calories consumed. Drink at least 8 - 8 oz glasses of water per day. Aim for at least 5 servings of vegetables & 4 servings of fruit per day. Use whole grain when possible. Avoid sodas, alcohol & junk carbohydrates. Get in a good mix of aerobic & weight lifting exercises.
