Why Choose Orlistat? The Science Behind Fat Blocking
How Orlistat Works: The Fat-Blocking Mechanism
Orlistat works through a targeted mechanism that inhibits lipase enzymes in your digestive system. These enzymes are responsible for breaking down dietary fat so it can be absorbed into your bloodstream. When orlistat blocks approximately one third of these lipases, that proportion of fat cannot be digested or absorbed. Instead, unabsorbed fat passes naturally through your digestive system and is eliminated from your body.
This mechanism works locally in your gut - orlistat isn't absorbed into your bloodstream in significant amounts, making it different from appetite suppressants that act on your brain. The fat-blocking effect is directly related to your meal's fat content, which is why following a lower-fat diet maximises effectiveness while minimising side effects.
Orlistat vs Xenical: Same Mechanism, Different Prices
Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients and work through the same fat-blocking mechanism. Generic orlistat offers the same clinical effect at a lower cost - 4 weeks costs £32.99 (£29.69 with EDM10) compared to Xenical at £42.99 (£38.69 with EDM10). This saves approximately £9 per month while delivering identical fat-blocking benefits.
Alli 60mg provides the same mechanism at half the prescription dose, blocking a smaller proportion of dietary fat. While less potent than 120mg versions, it may suit those preferring a lower-strength starting point.
Clinical Evidence: Why the Mechanism Matters
Orlistat's lipase-inhibiting mechanism has been extensively studied in clinical trials. By blocking approximately one third of dietary fat absorption, orlistat can support weight management when combined with a reduced-calorie, lower-fat diet. The mechanism works consistently - every high-fat meal triggers the fat-blocking effect, helping reduce overall calorie intake from dietary fats.
Individual responses vary, but the mechanism remains constant. Patients following lower-fat diets (approximately 15g fat per meal) experience the mechanism's benefits with fewer gastrointestinal side effects, as there's less unabsorbed fat passing through their system.
Getting Started: From Mechanism to Treatment
Understanding how orlistat works helps you make an informed treatment decision. At EverydayMeds, UK-licensed prescribers assess your suitability through an online clinical consultation. If appropriate, they'll prescribe orlistat 120mg, Xenical 120mg, or recommend Alli 60mg based on your individual circumstances.
Our GPhC-registered Leicester pharmacy dispenses your prescription with next day delivery across the UK. Choose from 2-week starter packs (42 capsules) to 12-week supplies (252 capsules). All treatments include the prescription at the stated price - no separate GP fees.
Maximising the Fat-Blocking Effect
Now you understand orlistat's mechanism, you can optimise its fat-blocking benefits. Take one capsule with each main meal containing fat - the enzymes are inhibited precisely when needed. Skip doses if meals contain no fat, as there are no lipases to block. Spread your daily fat intake across three meals to maintain consistent fat-blocking throughout the day.
