Proven Fat-Blocking Science - Order Today

How Orlistat Actually Works to Block Fat

Orlistat works through a scientifically proven mechanism that inhibits lipase enzymes in your digestive system. These enzymes are responsible for breaking down dietary fat so it can be absorbed by your body. When orlistat blocks these enzymes, approximately one third of the fat you eat cannot be digested or absorbed. This unabsorbed fat passes naturally through your body, reducing the calories absorbed from fatty foods.

Why One Third Fat Blocking Matters for Weight Loss

By blocking approximately one third of dietary fat absorption, orlistat can significantly reduce your calorie intake from fat. This mechanism provides measurable support for weight management when combined with a reduced-calorie, lower-fat diet. The effect is directly related to the fat content of your meals - the more fat you eat, the more calories orlistat helps block. This is why the medication works best alongside dietary changes that reduce overall fat intake.

Orlistat vs Xenical vs Alli - Understanding Your Options

All three products use the same fat-blocking mechanism, but at different strengths. Prescription orlistat 120mg (£29.69 for 4 weeks with EDM10) and branded Xenical 120mg (£38.69 for 4 weeks with EDM10) contain the same active ingredient at full strength. Alli 60mg (£49.49 for 8 weeks with EDM10) provides half the dose for those preferring a lower-strength option. Each works by blocking approximately one third of dietary fat, but prescription strength may provide more significant support.

Fast Online Prescription Process

Getting orlistat through EverydayMeds is straightforward. Complete our online health questionnaire, and a UK-licensed prescriber will review your suitability. If appropriate, your prescription is issued and dispensed by our GPhC-registered Leicester pharmacy. With next-day delivery available, you can start your fat-blocking treatment quickly. The prescription is included in the price - no separate GP appointment needed.

Maximising Results with Orlistat

To get the best results from orlistat's fat-blocking mechanism, keep meals low in fat (approximately 15g per meal). This not only maximises weight loss support but also minimises gastrointestinal side effects. Take one capsule with each main meal containing fat, up to three times daily. The medication works best as part of a comprehensive weight management programme including regular exercise and behavioural support.
