Understanding how orlistat works reveals why it's such an effective weight management tool.

Available as generic orlistat 120mg from £15.20 or branded Xenical from £19.35 with code EDM10, this prescription medication works locally in your digestive system.

Why Orlistat's Mechanism Makes It Work for You

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 approximately one third of these enzymes, that proportion of fat passes through undigested and is eliminated naturally. This mechanism reduces calorie intake from fat without affecting your brain or metabolism.

When to Take Orlistat for Maximum Effect

Take one 120mg capsule with each main meal containing fat - breakfast, lunch, and dinner. The timing is crucial: take immediately before, during, or up to one hour after eating. If you skip a meal or eat something fat-free, skip that dose. At EverydayMeds, generic orlistat 84 capsules (4-week supply) costs £29.69 with EDM10, while Xenical costs £38.69 - both containing identical 120mg orlistat.

Why the Gut-Based Mechanism Works

Unlike appetite suppressants that act on the brain, orlistat works locally in your digestive system. Only minimal amounts enter your bloodstream. This targeted action means the unabsorbed fat - approximately one third of what you eat - is eliminated through normal bowel movements. This visible proof shows the medication is working effectively.

Optimising Results with Lower-Fat Meals

The mechanism works best when each meal contains around 15g fat or less. Higher fat meals increase gastrointestinal effects as more unabsorbed fat passes through your system. Spreading fat intake evenly across three meals maximises absorption blocking while minimising side effects. A multivitamin taken at bedtime helps replace fat-soluble vitamins.
