Why Orlistat's Fat-Blocking Mechanism Works for Weight Loss
How Orlistat Works vs GLP-1 Medications
Orlistat is not a GLP-1 medication. While GLP-1 treatments work by affecting hormones and brain signals, orlistat works through a completely different mechanism. It acts as a lipase inhibitor, working locally in your digestive system to block approximately one third of the fat you eat from being absorbed. This unabsorbed fat passes naturally through your body, reducing your calorie intake from dietary fat.
The Science Behind Orlistat's Fat-Blocking Action
Orlistat inhibits pancreatic and gastric lipases - enzymes responsible for breaking down dietary fat. When these enzymes are blocked, approximately one third of the fat in your meals cannot be digested or absorbed into your bloodstream. This mechanism has been proven in clinical studies over more than 20 years, making orlistat a trusted choice for weight management when combined with a reduced-calorie, lower-fat diet.
Why This Mechanism Makes Orlistat Effective
The fat-blocking action means fewer calories from fat enter your system, supporting weight loss alongside dietary changes. Generic orlistat 120mg costs just £29.69 for a 4-week supply (84 capsules) with code EDM10, while branded Xenical 120mg is £38.69 for the same period. Both contain identical active ingredients and work through the same proven mechanism.
Comparing Orlistat Strengths and Costs
Prescription-strength orlistat 120mg blocks approximately one third of dietary fat, available as generic orlistat from £15.20 (42 capsules, 2-week supply) or branded Xenical from £19.35 with EDM10. Alli 60mg offers a lower-strength option at £26.09 for 42 capsules (4-week supply). All work through the same lipase inhibitor mechanism, with higher doses providing greater fat-blocking effect.
