The Science Behind Fat Blocking - Why Buy Today

How Orlistat Actually Works in Your Body

Orlistat's mechanism is scientifically proven and straightforward. When you take Alli or prescription orlistat with a meal, it inhibits lipase enzymes in your digestive system. These enzymes normally break down dietary fat for absorption. With approximately one third of fat blocked, undigested fat passes through your body naturally. This isn't speculation - it's a clinically proven mechanism that reduces calorie intake from fat by roughly 30%.

Why This Mechanism Matters for Weight Loss

Understanding how orlistat blocks fat absorption explains why it works. Every gram of fat contains 9 calories. When orlistat prevents one third of dietary fat absorption, you're automatically reducing caloric intake without changing portion sizes. For example, a 15g fat meal normally provides 135 fat calories - with orlistat, approximately 45 of those calories pass through unabsorbed. This mechanism supports weight management when combined with a reduced-calorie, lower-fat diet.

Prescription Orlistat 120mg vs Alli 60mg

Both products contain the same active ingredient but at different strengths. Prescription orlistat 120mg provides maximum fat-blocking effect, while Alli 60mg offers a lower-strength option. At EverydayMeds, generic orlistat 120mg costs £32.99 for 4 weeks (£29.69 with EDM10), while Alli 60mg costs £28.99 for 4 weeks (£26.09 with EDM10). Xenical, the branded version, costs £42.99 for 4 weeks (£38.69 with EDM10). All options work through the same proven mechanism.

What to Expect When Fat Blocking Begins

The fat-blocking mechanism produces noticeable effects, particularly if you eat high-fat meals. Most people experience oily stools or urgent bowel movements when excess fat passes through. These effects confirm orlistat is working but can be minimised by keeping meals below 15g fat each. The mechanism works immediately with each dose - there's no waiting period for the fat-blocking effect to begin.

Maximising Results Through Understanding

Knowing how orlistat blocks approximately one third of dietary fat helps optimise results. Spread your daily fat intake across three main meals rather than eating one high-fat meal. Take your capsule immediately before, during, or within one hour of eating. If you skip a meal or eat a fat-free meal, you can skip that dose since there's no fat to block. This targeted approach maximises the mechanism's effectiveness.
