Why Orlistat's Fat-Blocking Mechanism Works
How Orlistat Blocks Fat Absorption
Orlistat works through a precise mechanism that targets fat digestion in your gut. When you eat, enzymes called lipases break down dietary fat so your body can absorb it. Orlistat inhibits these lipase enzymes, preventing approximately one third of the fat you consume from being digested and absorbed. This unabsorbed fat passes naturally through your digestive system, reducing your overall calorie intake from dietary fat.
Three Treatment Options Available
Generic orlistat 120mg offers the most cost-effective option at £32.99 for 4 weeks (£29.69 with EDM10). Branded Xenical 120mg contains identical active ingredient at £42.99 for 4 weeks (£38.69 with EDM10). Alli 60mg provides a lower-dose option at £54.99 for 8 weeks (£49.49 with EDM10). All three work through the same fat-blocking mechanism, with 120mg prescription strength blocking more dietary fat than the 60mg version.
Why the Mechanism Proves Effectiveness
Unlike stimulant-based weight loss treatments that affect your brain, orlistat works locally in your digestive system. This targeted approach means you can see direct evidence that it's working - the unabsorbed fat is eliminated from your body naturally. The mechanism is dose-dependent: prescription-strength 120mg (orlistat and Xenical) blocks approximately one third of dietary fat, while 60mg Alli blocks a smaller proportion. This scientific approach to weight management has been clinically proven in numerous studies.
Combining Fat-Blocking with Diet Changes
Orlistat's mechanism works best when combined with a reduced-calorie, lower-fat diet. Keeping meals to around 15g fat each minimises gastrointestinal side effects while maximising the weight management benefits. The fat-blocking action means you absorb fewer calories from dietary fat, supporting your weight loss efforts alongside lifestyle changes. Following a structured eating plan enhances the effectiveness of orlistat's proven mechanism.
