The Science Behind Orlistat's Weight Loss Effect
How Orlistat Blocks Fat Absorption
Orlistat works through a precise mechanism targeting lipase enzymes in your digestive system. These enzymes normally break down dietary fat so it can be absorbed into your body. Orlistat inhibits approximately one third of these lipase enzymes, preventing them from breaking down fat molecules. This undigested fat cannot be absorbed and passes naturally through your system, reducing calorie intake from dietary fat.
Why This Mechanism Proves Effectiveness
Unlike appetite suppressants that act on brain chemistry, orlistat's mechanism is directly observable. When you eat fat whilst taking orlistat, the blocked fat becomes evident in your bowel movements - proving the medication is working. This visible confirmation demonstrates that approximately one third of dietary fat is being blocked rather than stored as body fat. Generic orlistat 120mg delivers this proven mechanism from just £15.20 (4 weeks: £29.69 with EDM10).
Orlistat vs Xenical: Identical Mechanisms
Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients working through the same fat-blocking mechanism. The clinical effect is identical - both block approximately one third of dietary fat absorption. Generic orlistat offers significant savings (£29.69 vs £38.69 for 4 weeks with EDM10) whilst delivering the same proven mechanism. Some patients prefer branded Xenical, whilst others choose generic orlistat for better value.
Alli 60mg: Lower-Strength Mechanism
Alli contains half the orlistat dose (60mg vs 120mg), providing a gentler introduction to the fat-blocking mechanism. Whilst still effective, Alli 60mg blocks a smaller proportion of dietary fat compared to prescription-strength orlistat. This lower dose typically results in milder side effects, making it suitable for those preferring a gradual approach. Alli 60mg costs £26.09 for 4 weeks with code EDM10.
