How Orlistat Blocks Fat Absorption - The Science
Orlistat works through a clinically proven mechanism that blocks approximately one third of dietary fat from being absorbed into your body. The active ingredient inhibits lipase enzymes in your digestive system - these enzymes normally break down fat so it can be absorbed. When lipases are blocked, roughly one third of the fat you eat passes through undigested and is naturally eliminated. This local action in the gut means orlistat isn't significantly absorbed into your bloodstream, making it different from brain-acting appetite suppressants.
Best Timing: Take Orlistat With Each Main Meal
Take one orlistat 120mg capsule immediately before, during, or up to one hour after each main meal containing fat. This timing ensures the medication is present when lipase enzymes would normally break down dietary fat. If you skip a meal or eat a fat-free meal, you can skip that dose. Maximum three capsules daily - one with breakfast, lunch, and dinner. Generic orlistat 120mg costs £32.99 for 84 capsules (4-week supply), or £29.69 with discount code EDM10.
Why The Mechanism Matters For Your Results
Understanding how orlistat works helps explain why it's effective for weight management alongside a reduced-calorie, lower-fat diet. By blocking approximately one third of dietary fat absorption, orlistat reduces the calories you absorb from fat - the most calorie-dense nutrient at 9 calories per gram. This proven mechanism has been studied in clinical trials, demonstrating its effectiveness when combined with dietary changes. The unabsorbed fat provides direct feedback about your fat intake through gastrointestinal effects.
Generic Orlistat vs Xenical - Same Mechanism, Better Value
Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients and work through the same fat-blocking mechanism. The clinical effect is equivalent - both block approximately one third of dietary fat absorption. Generic orlistat offers significant savings: 4-week supply costs £29.69 with EDM10 versus £38.69 for Xenical, saving you over £100 annually. Whether you choose generic orlistat or Xenical depends on personal preference - the mechanism and results are identical.
Supporting Your Weight Management Programme
Orlistat's fat-blocking action works best alongside a structured approach including a reduced-calorie, lower-fat diet with no more than 30% of calories from fat. Keep meals to approximately 15g fat each to minimise gastrointestinal side effects while maximising the medication's effectiveness. A daily multivitamin taken at bedtime supports fat-soluble vitamin absorption. Regular physical activity enhances overall weight management outcomes.
