Understanding Orlistat's Fat-Blocking Action
How Orlistat Blocks Fat Absorption
Orlistat works through a scientifically proven mechanism that blocks approximately one third of the fat you eat from being absorbed. The active ingredient inhibits lipase enzymes in your digestive system that normally break down dietary fat. When these enzymes are blocked, roughly one third of consumed fat cannot be digested or absorbed into your body. This unabsorbed fat passes naturally through your digestive system and is excreted, reducing the calories your body receives from dietary fat.
Why This Mechanism Matters for Weight Loss
Understanding how orlistat works explains why it can support weight management when used alongside a reduced-calorie, lower-fat diet. By blocking approximately one third of dietary fat absorption, orlistat helps reduce your overall calorie intake from fat sources. This mechanism works locally in your gut rather than affecting your brain or central nervous system, making it different from appetite suppressants. The effect is directly related to the fat content of your meals - lower fat meals mean fewer gastrointestinal side effects while still supporting your weight management goals.
Available Orlistat Options at EverydayMeds
We stock three orlistat options, all working through the same fat-blocking mechanism. Generic orlistat 120mg offers the most cost-effective option at £32.99 for 84 capsules (4 weeks), or £29.69 with code EDM10. Xenical 120mg provides the branded version at £42.99 for 84 capsules (£38.69 with EDM10). Alli 60mg offers a lower-strength alternative at £54.99 for 84 capsules (8 weeks). All contain orlistat as the active ingredient, blocking approximately one third of dietary fat absorption through the same proven mechanism.
The Science Behind Fat Blocking
Orlistat specifically targets pancreatic and gastric lipases - enzymes essential for breaking down dietary triglycerides into absorbable fatty acids and glycerol. When orlistat binds to these enzymes, approximately one third of consumed fat remains undigested and unabsorbed. This mechanism has been extensively studied in clinical trials, demonstrating how the medication supports weight loss when combined with appropriate dietary changes. The remaining two thirds of dietary fat is still absorbed normally, ensuring your body receives essential fatty acids while reducing overall calorie intake.
Maximising Orlistat's Fat-Blocking Effect
To optimise how orlistat works, distribute your daily fat intake evenly across three main meals, keeping each meal to approximately 15g fat or less. Take one orlistat 120mg capsule with each main meal containing fat, or skip the dose if a meal contains no fat. This approach maximises the fat-blocking mechanism while minimising gastrointestinal side effects. The medication works best as part of a structured weight management programme including a reduced-calorie, lower-fat diet and increased physical activity.
