How Prescription Weight Loss Treatment Works

Reviewed by Mostafa Damghani · 03/07/2026

Does Alli Weight Loss Work? Understanding Fat Blocker Medication

Alli contains orlistat, a clinically studied prescription weight loss ingredient that works by blocking the absorption of approximately one third of dietary fat. Unlike appetite suppressants that act on the brain, orlistat works locally in the digestive system by inhibiting lipase enzymes responsible for breaking down fat. This unabsorbed fat passes naturally through the body, potentially reducing calorie intake from dietary fat when used alongside a reduced-calorie, lower-fat diet and increased physical activity.

Prescription Weight Loss Options at EverydayMeds

We offer three orlistat-based treatments following online clinical assessment by UK-licensed prescribers. Generic orlistat 120mg provides the most cost-effective option at £32.99 for 4 weeks (£29.69 with EDM10). Branded Xenical 120mg contains the identical active ingredient at £42.99 for 4 weeks (£38.69 with EDM10). Alli 60mg offers a lower-strength option at £54.99 for 8 weeks (£49.49 with EDM10). All options require individual suitability assessment and work best when combined with dietary and lifestyle changes.

Clinical Assessment Process

Starting prescription weight loss treatment requires a clinical assessment by a qualified UK healthcare professional. Our streamlined online consultation reviews your medical history, current medications, and weight management goals. Following prescriber approval, medication is dispensed by our GPhC-registered Leicester pharmacy with discreet next-day delivery across the UK. The prescription is included in the price - no separate GP appointment needed.

Who May Be Suitable for Prescription Fat Blockers

Orlistat may be prescribed for adults with a BMI of 30 kg/m² or above, or those with a BMI of 28 kg/m² or above with weight-related health conditions such as type 2 diabetes or high blood pressure. Suitability depends on individual health circumstances and is determined through clinical assessment. Treatment must always be used alongside a structured weight management programme including dietary changes and increased activity.

Managing Treatment Effectively

Prescription fat blockers work most effectively when dietary fat intake is kept low - approximately 15g fat per meal spread across three main meals. This approach not only supports weight management but significantly reduces the likelihood of gastrointestinal side effects. Most patients find that side effects diminish as they adapt to a lower-fat eating pattern. A daily multivitamin is recommended, taken at bedtime at least 2 hours after your last orlistat dose.
