How Orlistat's Fat-Blocking Mechanism Drives Results
How Orlistat Works: The Science Behind Fat Blocking
Orlistat works through a precise mechanism called lipase inhibition. When you eat dietary fat, your body produces enzymes called lipases to break down that fat for absorption. Orlistat blocks these lipase enzymes in your digestive system, preventing approximately one third of dietary fat from being digested and absorbed. This unabsorbed fat passes naturally through your body, effectively reducing the calories you absorb from fat. Whether you choose generic orlistat at £32.99 for 4 weeks or branded Xenical at £42.99, you're getting exactly the same 120mg active ingredient with identical fat-blocking effects.
Why "Approximately One Third" Matters for Your Results
It's crucial to understand that orlistat blocks approximately one third of dietary fat - not all fat. This specific mechanism means the remaining two thirds of fat is still absorbed normally, which is why combining orlistat with a reduced-calorie, lower-fat diet maximises results while minimising side effects. The more fat in your meal, the more unabsorbed fat passes through your system, which can cause gastrointestinal side effects. Keeping meals to around 15g fat each helps orlistat work effectively while reducing unwanted effects. At EverydayMeds, our 8-week supply (168 capsules) costs £63.99 or £57.59 with EDM10, giving you time to establish this lower-fat eating pattern.
Orlistat vs Alternatives: Local Action, Proven Results
Unlike appetite suppressants that act on your brain, orlistat works locally in your gut and isn't significantly absorbed into your bloodstream. This targeted mechanism explains why orlistat has been prescribed safely for decades and remains a first-line prescription weight loss treatment in the UK. The fat-blocking action is direct and measurable - you may notice oily stools when eating higher-fat meals, which actually confirms the medication is working as intended. This visible proof of mechanism gives many patients confidence in their treatment choice.
Generic Orlistat vs Xenical: Same Mechanism, Different Price
Whether you choose generic orlistat or branded Xenical, you're getting identical 120mg capsules with the same lipase-inhibiting mechanism. The active ingredient, dose, and fat-blocking effect are clinically equivalent. Generic orlistat costs £95.99 for 12 weeks (£86.39 with EDM10) compared to Xenical at £128.99 (£116.09 with EDM10) - a significant saving for the same therapeutic effect. Some patients prefer the Xenical brand, while others choose generic orlistat for value. Both require the same online clinical assessment through our qualified UK prescribers.
