If you're really serious and think you can stick to a rigorous program for a week, try this and it WILL work without damaging your health. Eat four meals a day of a lean protein and low-glycemic carb (like a chicken breast and broccoli, or white fish and green beans, etc.). Skip red meat and starchy carbs like potatoes or rice, no sugar or dairy. Four meals means eating about every three hours and nothing after 6 or 7 p.m. This will seem like a lot of food and you may get sick of eating! Don't think that two meals a day will be better - they won't. Your body needs incoming food to fuel your metabolism. Exercise as vigorously as you are comfortable with for 30-40 minutes twice a day (morning and evening). Drink approx. a gallon of water a day if you can manage it. You will lose 3-5 lbs, no problem (some water, but some fat, too). Do not do this for more than a couple of weeks (if you could even stand it that long....chicken and broccoli get mighty old after 14 days) because your body needs a variety of foods to provide the nutrients you need to stay healthy in the long term. This isn't an easy program to stay with because it gets really boring, but if you're desperate it will work and you will still feel healthy.
