How Much Weight Could I Lose Using Alli?
Alli can help you lose weight, but the weight loss likely won't be great — perhaps just a few pounds more than you would lose with diet and exercise alone. Only a small number of studies have evaluated the effectiveness of
Alli. And many of the weight-loss estimates are based on studies conducted on its prescription-strength counterpart,
Xenical.
The average weight loss for prescription-strength
Xenical is modest — about 6 pounds greater than diet and exercise alone after one year. So at half the strength,
Alli could conceivably result in an average of 3 pounds lost in a year in addition to the approximately 8 pounds you could expect to lose from diet and exercise alone.
