How Orlistat Works: The Science Behind Fat Blocking
Understanding Orlistat's Immediate Mechanism of Action
Orlistat begins working with your very first dose, acting immediately in your digestive system to block approximately one third of dietary fat absorption. Unlike appetite suppressants that affect the brain, orlistat works locally in your gut by inhibiting lipase enzymes responsible for breaking down dietary fat. When these enzymes are blocked, unabsorbed fat passes naturally through your body rather than being stored as calories.
What Happens When You Take Orlistat
Each orlistat 120mg capsule taken with meals immediately starts blocking fat absorption from that specific meal. The active ingredient isn't absorbed into your bloodstream in significant amounts - instead, it works directly where fat digestion occurs. This targeted mechanism means orlistat can support weight management as part of a structured programme including a reduced-calorie, lower-fat diet and increased physical activity.
Orlistat vs Xenical vs Alli: Same Proven Mechanism
Whether you choose generic orlistat 120mg (£29.69 for 4 weeks with EDM10), branded Xenical 120mg (£38.69 for 4 weeks with EDM10), or lower-strength Alli 60mg (£26.09 for 4 weeks with EDM10), the fat-blocking mechanism remains the same. The 120mg prescription-strength products block approximately one third of dietary fat, while Alli 60mg blocks a smaller proportion due to its lower dose. All work immediately with each dose, though the prescription-strength options provide more potent fat blocking.
Why the Mechanism Matters for Your Weight Loss Journey
Understanding how orlistat blocks fat absorption explains why it may help reduce calorie intake when combined with dietary changes. By preventing approximately one third of dietary fat from being absorbed, orlistat can contribute to the calorie deficit needed for weight management. This mechanism works best when meals contain moderate fat levels - high-fat meals increase the likelihood of gastrointestinal side effects as more unabsorbed fat passes through your system.
