Orlistat works by blocking approximately one third of dietary fat absorption in your gut. Both generic orlistat 120mg and branded Xenical contain identical active ingredients at the same dose - the key difference is cost. Generic orlistat costs just £29.69 for a 4-week supply (with EDM10), compared to Xenical at £38.69.

Why Orlistat's Mechanism Makes It Worth Buying

How Orlistat's Fat-Blocking Mechanism Works

Orlistat works through a scientifically proven mechanism that inhibits lipase enzymes in your digestive system. These enzymes normally break down dietary fat for absorption. When orlistat blocks them, approximately one third of the fat you eat cannot be digested or absorbed into your body. This unabsorbed fat passes naturally through your digestive system, reducing calorie intake from dietary sources.

Unlike stimulant-based treatments that act on the brain, orlistat works locally in your gut and is not absorbed into your bloodstream in significant amounts. This targeted mechanism makes it a clinically effective option for weight management when used alongside a reduced-calorie, lower-fat diet.

Generic Orlistat vs Branded Xenical: Same Mechanism, Better Value

Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients at the same dose. The fat-blocking mechanism is clinically equivalent - approximately one third of dietary fat is prevented from absorption with both products. The key difference is cost-effectiveness.

Generic orlistat 120mg costs £32.99 for a 4-week supply (£29.69 with EDM10), whilst Xenical costs £42.99 (£38.69 with EDM10). You save approximately £9 per month choosing generic orlistat whilst receiving the same proven fat-blocking mechanism. For longer treatments, 12-week supplies of generic orlistat cost £95.99 (£86.39 with EDM10) compared to Xenical at £128.99 (£116.09 with EDM10).

Why This Mechanism Supports Effective Weight Management

Orlistat's lipase inhibition mechanism is designed to support weight reduction by reducing fat calorie absorption. When you consume a meal containing 15g of fat, orlistat may help prevent approximately 5g from being absorbed. Over time, this calorie reduction can contribute to weight loss when combined with a structured diet and exercise programme.

The mechanism works best when daily fat intake is spread evenly across three main meals, with no more than 15g fat per meal. This approach minimises gastrointestinal side effects whilst maximising the therapeutic benefit of the fat-blocking action.

Alli 60mg: Lower-Dose Alternative

Alli contains orlistat at 60mg - half the dose of prescription-strength products. This lower dose blocks a smaller proportion of dietary fat but may cause milder side effects. Alli 60mg costs £54.99 for an 8-week supply (£49.49 with EDM10), offering another option for those preferring a gentler starting approach.
