The Science Behind Why Orlistat Works
How Orlistat Blocks Fat Absorption
Orlistat works by inhibiting lipase enzymes in your digestive system. These enzymes normally break down dietary fat so it can be absorbed into 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 digestive system and is excreted, reducing your calorie intake from dietary fat.
Why This Mechanism Makes Orlistat Effective
Unlike stimulants that work in the brain, orlistat acts locally in your gut and is not absorbed into your bloodstream in significant amounts. This targeted mechanism means it directly reduces calories from fat without affecting your central nervous system. The science is straightforward - less fat absorbed means fewer calories contributing to weight gain when combined with a reduced-calorie, lower-fat diet.
Generic Orlistat vs Xenical - Same Mechanism, Different Price
Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients and work through exactly the same mechanism. Generic orlistat costs £29.69 for 4 weeks with EDM10, whilst Xenical costs £38.69 - a saving of £9 monthly. Clinically, they're equivalent. Some patients prefer branded Xenical, others choose generic orlistat for better value. The choice is yours following clinical assessment.
What to Expect When Orlistat Works
Because orlistat blocks approximately one third of dietary fat absorption, you may notice gastrointestinal effects - particularly if you eat high-fat meals. These effects are actually evidence the medication is working. Keeping fat intake to around 15g per meal significantly reduces side effects whilst maintaining the weight management benefits. A daily multivitamin taken at bedtime helps replace fat-soluble vitamins.
Alli 60mg - Lower Dose, Same Mechanism
Alli contains 60mg orlistat - half the prescription strength. It works through the same fat-blocking mechanism but at reduced intensity. Available from £26.09 for 4 weeks with EDM10, Alli may suit those preferring a gentler starting approach. However, prescription-strength 120mg orlistat typically provides more significant support for weight management goals.
