600 Calories??: 600 calories per day is not healthy for a male adult. Your body will go into starvation mode and your metabolic rate will drop. To lose weight insure that calories burned > calories consumed. Drink at least 8 - 8 oz glasses of water per day. Try for 8 hours of sleep/night. Aim for at least 5 servings of vegetables & 4 servings of fruit per day. Use whole grain when possible. Avoid sodas, alcohol
