Alli- orlistat weightloss aid formula is a program that starts with your commitment to adopting healthy eating habits. It combines the only FDA approved, over-the-counter weight loss product with an individually tailored support plan to help you achieve gradual and healthy weight loss. When you take alli along with a reduced-calorie, low-fat diet, you can lose 50% more weight than dieting alone. For example, instead of losing 10 pounds with diet alone, you can lose 15 pounds with the alli program. alli is safe - it works in your digestive system, not in your heart or brain. It will not cause jitters, sleeplessness, or a racing heart.
