Why Orlistat's Fat-Blocking Mechanism Makes It Effective
How Xenical Capsules Block Fat Absorption
Xenical capsules contain orlistat 120mg, which works by inhibiting lipase enzymes in your digestive system. These enzymes normally break down dietary fat so it can be absorbed into your body. When orlistat blocks these lipases, approximately one third of the fat you eat cannot be digested or absorbed. This unabsorbed fat passes naturally through your system, effectively reducing the calories your body takes in from fatty foods.
This mechanism works locally in your gut - orlistat is not absorbed into your bloodstream in significant amounts, making it different from appetite suppressants that act on your brain. You can order Xenical 120mg from £19.35 for 2 weeks (£21.50 normally) or choose generic orlistat 120mg from £15.20 for 2 weeks with code EDM10.
Why Approximately One Third Fat Blocking Works
Orlistat's ability to block approximately one third of dietary fat absorption has been clinically proven effective for weight management. This partial fat blocking allows your body to still absorb essential fatty acids while reducing overall calorie intake from fat. The mechanism means that higher-fat meals will have more calories blocked, while lower-fat meals produce fewer side effects.
For sustained weight management, this proven mechanism works best alongside a reduced-calorie, lower-fat diet. Our 12-week supplies offer the best value: Xenical 120mg for £116.09 (normally £128.99) or generic orlistat for £86.39 (normally £95.99) with EDM10.
Same Mechanism: Xenical vs Generic Orlistat
Both Xenical 120mg capsules and generic orlistat 120mg capsules contain identical amounts of the same active ingredient. This means they work through exactly the same fat-blocking mechanism - inhibiting lipase enzymes to prevent approximately one third of dietary fat absorption. The clinical effect is identical whether you choose branded Xenical or generic orlistat.
The key difference is cost: generic orlistat 120mg offers the same proven mechanism at lower prices. A 4-week supply costs £29.69 with EDM10 compared to £38.69 for branded Xenical. Both require the same online clinical assessment by our UK-licensed prescribers.
Understanding What You May Experience
Because orlistat blocks approximately one third of dietary fat, you may experience gastrointestinal side effects when eating fatty meals. These effects - including oily stools, increased bowel movements, or oily spotting - are actually signs that the mechanism is working. The unabsorbed fat has to leave your body somehow.
These side effects can be minimised by keeping meals low in fat (approximately 15g fat per meal). Many patients find side effects reduce over time as they adapt to a lower-fat diet. This fat-blocking mechanism also means orlistat may reduce absorption of fat-soluble vitamins, so a daily multivitamin taken at bedtime is recommended.
