Why Orlistat's Proven Mechanism Makes It Effective

How Orlistat Blocks Fat Absorption

Orlistat works by inhibiting lipase enzymes in your digestive system. These enzymes normally break down dietary fat so it can be absorbed into your body. When orlistat blocks these enzymes, approximately one third of the fat you eat cannot be digested or absorbed. This unabsorbed fat passes naturally through your digestive system and is excreted. The mechanism is simple, clinically proven, and doesn't affect your brain chemistry like other weight loss treatments.

Why One Third Fat Blocking Matters for Weight Loss

By blocking approximately one third of dietary fat absorption, orlistat can significantly reduce calorie intake from fat-rich meals. Fat contains 9 calories per gram, so this reduction can support meaningful weight loss when combined with a reduced-calorie, lower-fat diet. Generic orlistat 120mg at £29.69 for four weeks (with EDM10) offers excellent value for this clinically proven mechanism.

Orlistat vs Xenical: Same Proven Mechanism

Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients at the same dose. The fat-blocking mechanism is identical — both block approximately one third of dietary fat absorption. The key difference is cost: generic orlistat costs £29.69 for four weeks versus Xenical at £38.69 (with EDM10). Choose generic orlistat for value or branded Xenical if you prefer the original manufacturer.
