How Orlistat's Proven Mechanism Supports Weight Loss
How Orlistat 120mg Works in Your Body
Orlistat works through a simple, proven mechanism that blocks approximately one third of dietary fat absorption. Unlike appetite suppressants that act on your brain, orlistat works locally in your digestive system by inhibiting lipase enzymes responsible for breaking down dietary fat. When these enzymes are blocked, roughly one third of the fat you eat cannot be digested or absorbed - instead, it passes naturally through your body. This mechanism directly reduces calories from fat, supporting weight loss when combined with a reduced-calorie, lower-fat diet.
What to Eat While Taking Orlistat 120mg
The key to orlistat's effectiveness lies in keeping your meals low in fat. Aim for no more than 15g of fat per meal, spreading your daily fat intake evenly across breakfast, lunch and dinner. High-fat meals not only reduce orlistat's effectiveness but significantly increase gastrointestinal side effects. Focus on lean proteins, vegetables, fruits and whole grains. When you understand this mechanism - that orlistat blocks fat absorption - you realise why a lower-fat diet maximises both effectiveness and comfort.
Why Orlistat's Mechanism Proves It Works
The beauty of orlistat's mechanism is its transparency - you can literally see it working. The unabsorbed fat that passes through your system is visible proof that orlistat is blocking approximately one third of dietary fat absorption. This isn't a placebo effect or uncertain mechanism - it's a direct, measurable reduction in fat calories. At EverydayMeds, generic orlistat 120mg costs £32.99 for 4 weeks (£29.69 with EDM10), while branded Xenical costs £42.99 for 4 weeks (£38.69 with EDM10). Both contain identical orlistat 120mg with the same proven mechanism.
Orlistat vs Xenical vs Alli - Same Mechanism, Different Strengths
All three products work through the same fat-blocking mechanism, but at different strengths. Orlistat 120mg and Xenical 120mg are identical prescription medicines blocking approximately one third of dietary fat. Alli contains 60mg orlistat - half the prescription strength - so blocks a smaller proportion of fat. The mechanism remains the same: lipase inhibition leading to reduced fat absorption. For maximum effectiveness, most patients choose prescription-strength 120mg orlistat from £29.69/month rather than lower-strength alternatives.
