The problem with diets is that they work short time but are not a fix. Diet aids such as pills, herbs and liquids do more harm than good. Recognizing you have a problem and recognizing how long it took you to become overweight and how long it will take to fix it is important. Its a lifestyle change. I would suggest that you take a look at a food regimen that diabetics use by counting carbs, protein, fat and fiber and sticking to it combined with at least thirty minutes of cardio type exercises daily. Increase as your ability increases. Give yourself six months and I will assure you that you will be down 50 pounds at least within 6 months. Remember its a lifestyle change.
