The Fat-Blocking Science That Drives Results
How Orlistat Actually Blocks Fat Absorption
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 eat cannot be digested or absorbed into your body. This unabsorbed fat passes naturally through your system, reducing the calories your body can store. The mechanism is local to your gut - orlistat isn't absorbed into your bloodstream significantly, making it a targeted approach to weight management.
Why "One Third" Matters for Your Results
The precision of orlistat's mechanism - blocking approximately one third of dietary fat - provides measurable calorie reduction without completely eliminating fat absorption. Your body still absorbs essential fats and fat-soluble vitamins from the remaining two thirds. This balanced approach supports sustainable weight management when combined with a reduced-calorie, lower-fat diet. Generic orlistat 120mg (£32.99 for 4 weeks) and Xenical 120mg (£42.99 for 4 weeks) both deliver this exact mechanism.
Choosing Between Generic Orlistat and Branded Xenical
Both contain identical 120mg orlistat doses with the same fat-blocking mechanism. Generic orlistat offers the same clinical effect at lower cost - perfect for longer treatment courses. Our 12-week generic supply costs £95.99 (£86.39 with EDM10) versus £128.99 for Xenical (£116.09 with EDM10). Some patients prefer branded Xenical, whilst others choose generic orlistat for value. Either way, you receive the proven fat-blocking mechanism that makes orlistat effective.
Lower-Strength Option: Alli 60mg
Alli provides half the orlistat dose at 60mg, blocking a smaller proportion of dietary fat than prescription strength. Our 8-week Alli supply costs £54.99 (£49.49 with EDM10). Whilst less potent than 120mg formulations, Alli offers an alternative for those preferring lower-strength treatment. The mechanism remains identical - lipase inhibition leading to reduced fat absorption.
What to Expect When Orlistat Starts Working
The fat-blocking mechanism produces noticeable gastrointestinal effects - these are actually signs that orlistat is working. Oily stools, increased bowel frequency, and oily spotting occur when unabsorbed fat passes through your system. Keeping meal fat content low (approximately 15g per meal) significantly reduces these effects whilst maintaining the weight management benefits. Most patients adapt within the first few weeks as their diet adjusts.
