Why Understanding the Mechanism Matters for Your Purchase
How Orlistat Actually Works in Your Body
Orlistat works through a scientifically proven mechanism that targets dietary fat absorption. When you eat, enzymes called lipases break down fat so your body can absorb it. Orlistat inhibits these lipase enzymes in your digestive system, preventing approximately one third of the fat you consume from being absorbed. This unabsorbed fat passes naturally through your body, reducing your calorie intake from dietary fat.
This mechanism makes orlistat fundamentally different from appetite suppressants that act on the brain. Instead, orlistat works locally in your gut and is not significantly absorbed into your bloodstream. This targeted action explains why orlistat can support weight management when used alongside a reduced-calorie, lower-fat diet.
Why This Mechanism Proves Orlistat Works
The lipase inhibition mechanism provides measurable, predictable results. By blocking approximately one third of dietary fat absorption, orlistat creates a calorie deficit that can contribute to weight loss. The remaining two thirds of fat is still digested normally, ensuring your body receives essential nutrients whilst reducing overall calorie intake.
Generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients at the same dose, providing the same lipase inhibition effect. A 4-week supply of generic orlistat costs £29.69 with EDM10, whilst Xenical costs £38.69 with EDM10 - both delivering identical clinical mechanisms.
What You Can Expect When Ordering Online
Understanding how orlistat works helps set realistic expectations. The gastrointestinal effects you may experience - such as oily stools or urgent bowel movements - are actually signs the medication is working by preventing fat absorption. These effects are more noticeable with high-fat meals, which is why following a lower-fat diet maximises results whilst minimising side effects.
Following your online clinical assessment by a UK-licensed prescriber, you'll receive guidance on keeping meals to approximately 15g fat each. This dietary approach works synergistically with orlistat's mechanism, optimising both effectiveness and tolerability.
Comparing Your Options - Same Mechanism, Different Prices
All orlistat products work through the same lipase inhibition mechanism. Generic orlistat 120mg offers the most cost-effective option at £57.59 for 8 weeks with EDM10. Xenical 120mg provides the same mechanism at £78.29 for 8 weeks with EDM10. Alli 60mg contains half the dose, blocking a smaller proportion of dietary fat, priced at £49.49 for 8 weeks with EDM10.
Your prescriber will recommend the most appropriate option based on your clinical assessment, but understanding the mechanism helps inform your choice between generic and branded options.
