Enhancing the product description for “Xenical 120mg Capsules 84’s” based on the information found, the active ingredient Orlistat effectively inhibits the enzyme lipase, responsible for breaking down dietary fats in the intestine. By preventing the absorption of dietary fats, Xenical aids in reducing caloric intake, which can lead to weight loss. It’s crucial to pair Xenical with a balanced, mildly hypocaloric diet that contains about 30% of calories from fat to achieve the best results. The recommended dosage is one 120mg capsule with each main meal containing fat, up to three times a day. If a meal is missed or contains no fat, the Xenical dose should be skipped.
