Why Orlistat's Mechanism Makes It Effective
How Orlistat's Fat-Blocking Mechanism Works
Orlistat works by inhibiting pancreatic and gastric lipases - enzymes essential for breaking down dietary fat. When you take orlistat with meals, it blocks approximately one third of the fat you consume from being absorbed into your bloodstream. This unabsorbed fat passes naturally through your digestive system, reducing the calories your body takes in from dietary fat.
This mechanism is why orlistat requires a reduced-calorie, lower-fat diet to work effectively. The medication targets fat absorption directly in your gut, making it fundamentally different from stimulant-based weight loss treatments that affect brain chemistry.
Orlistat Dosing: Getting the Mechanism Right
Proper dosing ensures orlistat's fat-blocking mechanism works optimally. Take one 120mg capsule three times daily with each main meal containing fat. If you skip a meal or eat a fat-free meal, you can omit that dose. This dosing schedule aligns with your body's natural fat digestion process.
At EverydayMeds, orlistat 120mg is available in convenient pack sizes: 42 capsules (2 weeks, £16.89), 84 capsules (4 weeks, £32.99), 168 capsules (8 weeks, £63.99), and 252 capsules (12 weeks, £95.99). Use code EDM10 for 10% off every order.
Why the Mechanism Proves Orlistat Works
Orlistat's mechanism provides visible proof it's working. When following a lower-fat diet, many patients experience minimal side effects. However, eating high-fat meals whilst taking orlistat often results in gastrointestinal effects like oily stools - direct evidence that dietary fat is being blocked from absorption.
This feedback mechanism helps patients understand their fat intake and adjust their diet accordingly. The medication essentially teaches your body to process meals differently, supporting long-term dietary changes alongside immediate fat-blocking effects.
Orlistat vs Xenical: Same Mechanism, Different Prices
Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients and work through the same lipase inhibition mechanism. Xenical starts from £21.50 for 42 capsules (£19.35 with EDM10), whilst generic orlistat offers the same clinical effect from £16.89 (£15.20 with EDM10).
Alli 60mg uses the same mechanism at half the dose, available from £28.99 for 42 capsules. Your prescriber will determine which strength suits your individual circumstances following clinical assessment.
