How Orlistat's Fat-Blocking Action Supports Weight Loss
The Science Behind How Orlistat Capsules Work
Orlistat capsules work through a specific mechanism that blocks approximately one third of dietary fat absorption. The active ingredient inhibits lipase enzymes in your digestive system, preventing them from breaking down fat molecules. When these enzymes cannot function properly, roughly one third of the fat you eat passes through your body unabsorbed and is eliminated naturally. This mechanism works locally in the gut and is not absorbed into your bloodstream in significant amounts.
Why Fat-Blocking Helps Weight Management
By blocking approximately one third of dietary fat absorption, orlistat reduces the calories absorbed from fat-containing meals. Since fat provides 9 calories per gram compared to 4 calories from carbohydrates or protein, this reduction can significantly impact overall calorie intake. The unabsorbed fat passes through your digestive system, which explains why maintaining a lower-fat diet is essential for minimising side effects while maximising weight management benefits.
Orlistat 120mg vs Xenical: Same Mechanism, Different Prices
Both generic orlistat 120mg and branded Xenical contain identical active ingredients and work through the same fat-blocking mechanism. Generic orlistat costs £32.99 for 84 capsules (4 weeks), reduced to £29.69 with code EDM10. Xenical costs £42.99 for the same 4-week supply, saving you approximately £13 when choosing generic orlistat. Both options require prescription following clinical assessment by a UK-licensed prescriber through our online consultation.
Alli 60mg: Lower-Strength Fat Blocking
Alli contains 60mg orlistat, exactly half the prescription dose. This lower strength blocks a smaller proportion of dietary fat compared to 120mg capsules. Alli 60mg costs £28.99 for 42 capsules (4-week supply), or £26.09 with EDM10. Some people prefer starting with lower-strength Alli, while others choose prescription-strength 120mg for maximum fat-blocking effect. Your prescriber can advise which strength suits your weight management goals.
Understanding Treatment Duration and Results
Orlistat's fat-blocking mechanism begins working with your first dose, but weight management results develop gradually when combined with a reduced-calorie, lower-fat diet. Our 8-week orlistat supply (168 capsules) costs £63.99, reduced to £57.59 with EDM10, while 12-week supplies cost £95.99 (£86.39 with EDM10). Extended treatment allows the fat-blocking mechanism to support sustained weight management alongside dietary changes.
