Orlistat (Xenical): A Proven Weight Loss Solution
What is Orlistat (Xenical)?
Orlistat, branded as Xenical, is a clinically proven prescription weight loss medication designed to help individuals with a body mass index (BMI) over 30, or 27 with weight-related conditions. It works by blocking fat absorption, preventing up to 30% of dietary fat from being stored in the body. When combined with a healthy diet and exercise, Orlistat can help users lose 5-10% of their body weight during a treatment cycle.
What’s the Difference Between Orlistat and Xenical?
- Orlistat: Generic version containing the same active ingredient as Xenical.
- Xenical: Branded version of Orlistat with a 120mg dose.
- Alli: Over-the-counter version with a lower 60mg dose, blocking 25% of dietary fat absorption.
How Does Orlistat Work?
Orlistat targets dietary fat in the digestive system by blocking the enzyme lipase, which is responsible for breaking down fat. This prevents approximately one-third of the fat consumed in a meal from being absorbed and stored in the body. Instead, the fat passes through the digestive system and is excreted.
How Long Does Orlistat Take to Work?
When combined with a low-fat diet and regular exercise:
- Noticeable Results: Within 2–3 months.
- Effective Weight Loss: Most users lose at least 5% of their starting weight in 12 weeks.
If no significant progress is made after 12 weeks, consult your healthcare professional for alternative treatments.
Tips for Maximising Results with Orlistat
- Maintain a Low-Fat Diet: Keep fat intake below 30% of total calories to reduce the likelihood of side effects.
- Exercise Regularly: Incorporate both cardio and strength training exercises for best results.
- Take Orlistat as Directed: One capsule with water during or within an hour after each meal.
Recommended Diet While Taking Orlistat
A balanced, low-fat diet enhances the effectiveness of Orlistat. Examples of healthy meals include:
- Lean protein (e.g., chicken, fish, or tofu)
- Whole grains (e.g., brown rice or quinoa)
- Plenty of vegetables and fruits
- Low-fat dairy products
Avoid high-fat meals as they may increase the risk of side effects like oily stools.
