Why Understanding the Mechanism Matters for Your Purchase

How Orlistat Works in Your Digestive System

Orlistat works by inhibiting lipase enzymes in your gut that are responsible for breaking down dietary fat. When these enzymes are blocked, approximately one third of the fat you consume cannot be digested or absorbed into your body. This unabsorbed fat passes naturally through your digestive system and is eliminated. The mechanism is entirely local to your gut - orlistat is not absorbed into your bloodstream in significant amounts, which explains its targeted action on fat absorption specifically.

Why One Third Fat Blocking Supports Weight Management

By preventing approximately one third of dietary fat absorption, orlistat can help reduce your calorie intake from fat when used alongside a reduced-calorie, lower-fat diet. Fat contains 9 calories per gram - more than double that of carbohydrates or protein. Even blocking one third of fat absorption can contribute meaningfully to creating the calorie deficit needed for weight loss. This mechanism explains why orlistat may support weight management when combined with dietary and lifestyle changes.

Choose Your Orlistat Option at EverydayMeds

Understanding how orlistat works helps you choose between our options. Generic orlistat 120mg offers the same fat-blocking mechanism as branded Xenical at a lower cost - 4-week supply from £29.69 with EDM10 versus £38.69 for Xenical. Both contain identical 120mg orlistat and work through the same mechanism. Alli 60mg provides half the dose for those preferring lower-strength treatment. All require clinical assessment by our UK-licensed prescribers.

What to Expect When Orlistat Blocks Fat

The fat-blocking mechanism produces predictable effects. You may experience oily stools, increased bowel frequency, or urgent bowel movements - these are signs the medication is working by preventing fat absorption. Keeping meals low in fat (approximately 15g per meal) minimises these effects while maintaining the weight management benefits. The unabsorbed fat must be eliminated, which explains the gastrointestinal side effects that improve as you adapt your diet.
