Why Orlistat's Proven Mechanism Makes It Worth Buying
How Orlistat Blocks Fat Absorption - The Science
Orlistat works through a precise mechanism that targets lipase enzymes in your digestive system. These enzymes normally break down dietary fat so your body can absorb it. When you take orlistat 120mg capsules, the active ingredient inhibits these lipases, preventing approximately one third of the fat you eat from being digested. This unabsorbed fat cannot enter your bloodstream and passes naturally through your body.
This proven mechanism explains why orlistat is the UK's most prescribed weight loss medication. Unlike stimulants that affect your brain, orlistat acts locally in your gut with minimal absorption into your bloodstream. This targeted action makes it a scientifically sound choice for weight management support.
Generic Orlistat vs Xenical - Same Mechanism, Different Prices
Whether you choose generic orlistat 120mg or branded Xenical 120mg, you get exactly the same fat-blocking mechanism. Both contain identical 120mg doses of orlistat that block approximately one third of dietary fat absorption. The clinical effect is identical - the main difference is cost.
Generic orlistat starts at £32.99 for a 4-week supply (84 capsules), or £29.69 with code EDM10. Xenical costs £42.99 for the same 4-week supply, or £38.69 with discount code EDM10. That's nearly £10 monthly savings with generic orlistat while getting the exact same fat-blocking mechanism.
Why the Mechanism Proves Orlistat Works
Understanding how orlistat blocks fat absorption explains why it's clinically proven for weight management. When you eat a meal containing 45g of fat, orlistat prevents approximately 15g from being absorbed - that's roughly 135 fewer calories per meal. Over time, this calorie reduction can support significant weight management when combined with a reduced-calorie, lower-fat diet.
The mechanism also explains orlistat's side effects. The unabsorbed fat must leave your body somehow, which can cause oily stools or spotting. These effects actually prove the medication is working by blocking fat absorption. Keeping meals low in fat (approximately 15g per meal) minimises side effects while maintaining the weight management benefits.

Supporting Your Weight Management Journey
Orlistat's mechanism works best alongside lifestyle changes. The fat-blocking action is most effective when you follow a reduced-calorie, lower-fat diet with regular physical activity. This combination maximises the calorie reduction from blocked fat absorption while building sustainable weight management habits.
Take one 120mg capsule with each main meal containing fat, up to three times daily. If you skip a meal or eat something fat-free, you can skip that dose. The mechanism only works when there's dietary fat present for the lipase enzymes to act upon.
