The Science Behind How Orlistat Blocks Fat
Orlistat works through a precise scientific mechanism that targets fat digestion in your digestive system. When you eat a meal containing fat, your body naturally produces lipase enzymes to break down that fat so it can be absorbed. Orlistat inhibits these lipase enzymes, preventing them from breaking down approximately one third of the dietary fat you consume. This unabsorbed fat cannot enter your bloodstream and instead passes naturally through your body.
This mechanism makes orlistat fundamentally different from appetite suppressants that affect your brain. Orlistat acts locally in your gut, blocking fat absorption at the source. The more you understand this proven mechanism, the more confident you can be in your purchase decision.
Why the Mechanism Proves Orlistat Works
The lipase inhibition mechanism is why orlistat has been clinically studied and approved for weight management. By blocking approximately one third of dietary fat absorption, orlistat can reduce the calories your body absorbs from fat-containing meals. This creates a calorie deficit that may support weight loss when combined with a reduced-calorie, lower-fat diet and increased physical activity.
At EverydayMeds, we stock three proven orlistat options: Alli 60mg from £28.99, generic orlistat 120mg from £16.89, and branded Xenical 120mg from £21.50. All contain the same active ingredient with the same fat-blocking mechanism - the difference is strength and cost.
What You'll Experience When Orlistat Blocks Fat
Understanding the mechanism helps explain what you may experience. When orlistat blocks approximately one third of dietary fat, that unabsorbed fat must leave your body. This can cause gastrointestinal effects like oily stools, increased bowel movements, or oily spotting. These effects are actually evidence that the fat-blocking mechanism is working.
You can minimise these effects by keeping your fat intake low - approximately 15g fat per meal. When you eat high-fat meals, more fat gets blocked and more side effects occur. The mechanism works consistently, so controlling your fat intake controls your experience.
Choosing Your Orlistat Strength
Now you understand the mechanism, you can choose the right strength for your needs. Alli 60mg provides the fat-blocking mechanism at half the prescription dose. Our 4-week supply costs £28.99 (£26.09 with EDM10). For maximum fat-blocking effect, prescription orlistat 120mg blocks approximately one third of dietary fat more effectively. Our 4-week supply costs £32.99 (£29.69 with EDM10).
Xenical 120mg offers the same mechanism as generic orlistat but as the original branded version. Some patients prefer the branded option for £42.99 per 4-week supply (£38.69 with EDM10). All three work through identical lipase inhibition - your choice depends on strength preference and budget.
