The Science Behind Orlistat's Fat-Blocking Action
How Orlistat Blocks Fat Absorption in Your Digestive System
Orlistat works through a scientifically proven mechanism that inhibits lipase enzymes in your gut. These enzymes are responsible for breaking down dietary fat into smaller molecules that can be absorbed. When you take orlistat 120mg with meals, it blocks approximately one third of the fat you eat from being digested and absorbed into your body. This unabsorbed fat passes naturally through your digestive system and is eliminated, reducing your overall calorie intake from dietary fat.
Why This Mechanism Makes Orlistat Effective for Weight Management
Understanding how orlistat works explains why it's clinically effective for weight management alongside a reduced-calorie, lower-fat diet. Unlike appetite suppressants that act on the brain, orlistat works locally in your gut where fat digestion occurs. Generic orlistat 120mg costs just £29.69 for 4 weeks with code EDM10, while branded Xenical 120mg costs £38.69 for the same period. Both contain identical active ingredients and block the same proportion of dietary fat - approximately one third.
Orlistat and Keto Diet Compatibility
When following a keto diet, orlistat can support your weight management goals by blocking approximately one third of the dietary fat you consume. Since keto diets are typically high in fat, orlistat helps reduce the total calories absorbed from fat while allowing you to maintain ketosis. The mechanism works regardless of fat source - whether from avocados, nuts, oils, or other keto-friendly foods. Starting with our 2-week supply at £15.20 (orlistat 120mg with EDM10) lets you trial the treatment affordably.
What Happens When You Take Orlistat
Within hours of taking your first orlistat capsule, the medication begins inhibiting lipase enzymes in your digestive system. You take one 120mg capsule with each main meal containing fat, up to three times daily. The fat-blocking action is immediate and directly related to the fat content of your meal. Lower-fat meals result in fewer side effects, while the approximately one third of dietary fat that isn't absorbed passes through naturally. Our 8-week supply (168 capsules) costs £57.59 with EDM10, providing consistent fat-blocking support.
