How Orlistat's Fat-Blocking Mechanism Supports Weight Loss
The Science Behind Orlistat's Fat-Blocking Action
Orlistat works by inhibiting lipase enzymes in your digestive system that normally break down dietary fat. When these enzymes are blocked, approximately one third of the fat you consume cannot be digested or absorbed into your body. This unabsorbed fat passes naturally through your digestive system, reducing your overall calorie intake from dietary fat. The mechanism is purely local to your gut - orlistat is not absorbed into your bloodstream in significant amounts, making it different from stimulant-based weight loss medications.
Why Results Vary: Understanding Your Response
If you're not seeing expected results on orlistat, the fat-blocking mechanism may help explain why. Orlistat only affects dietary fat - it doesn't block carbohydrates, protein, or alcohol calories. For the medication to work effectively, your daily fat intake should be spread evenly across three main meals, with no more than approximately 15g fat per meal. High-fat meals not only increase side effects but may overwhelm the fat-blocking capacity. Generic orlistat 120mg at £63.99 for 8 weeks (£57.59 with EDM10) provides the same lipase-inhibiting effect as branded alternatives.
Maximising Orlistat's Fat-Blocking Benefits
The mechanism works best when combined with a structured approach. Take one 120mg capsule with each main meal containing fat - up to three capsules daily. If a meal contains no fat, you can skip that dose as there's nothing for the lipase inhibitors to block. The unabsorbed fat will cause gastrointestinal effects, which are actually signs the mechanism is working. Xenical 120mg at £42.99 for 4 weeks (£38.69 with EDM10) contains the same active orlistat but some patients prefer the branded option.
Comparing Your Options: Same Mechanism, Different Prices
Understanding how orlistat works helps you choose between options. Generic orlistat 120mg, branded Xenical 120mg, and lower-strength Alli 60mg all work through lipase inhibition, but at different potencies. The 120mg prescription-strength versions block more dietary fat than Alli's 60mg dose. Our 12-week supply of generic orlistat costs £95.99 (£86.39 with EDM10) compared to Xenical at £128.99 (£116.09 with EDM10) - both providing identical fat-blocking mechanisms through the same active ingredient.
