Who Makes Alli?
Alli is made by GlaxoSmithKline Consumer Healthcare.
How Does It Work?
Alli works by decreasing the absorption of fat from your diet. The stomach and intestines have enzymes called lipases that break down fat into smaller molecules, which are then absorbed from your digestive tract. Alli binds to lipases and inhibits their activity, helping to decrease fat absorption. The drug does not have any effect on carbohydrates or protein.
Effects of Alli
On average, Alli tends to prevent the absorption of approximately 25 percent of the fat in the diet. Studies have shown that when used in combination with dieting, this medication helps people lose 50 percent more weight than with just dieting alone. The exact amount of weight loss people experience while taking the drug depends on several factors, including their diet and exercise habits. It is reasonable to expect a modest and gradual weight loss with Alli combined with dieting -- about one to two pounds per week.
