Why Choose Orlistat Based on How It Works
How Orlistat 120mg Works in Your Body
Orlistat works by inhibiting lipase enzymes in your digestive system. These enzymes normally break down dietary fats so they can be absorbed. When orlistat blocks these enzymes, approximately one third of the fat you eat cannot be digested or absorbed into your bloodstream. This unabsorbed fat passes naturally through your body, reducing the total calories absorbed from fat-rich meals.
Unlike appetite suppressants that act on the brain, orlistat works locally in your gut and is not significantly absorbed into your bloodstream. This targeted mechanism means orlistat only affects dietary fat absorption - it does not block carbohydrates, proteins, or other nutrients.
Why This Mechanism Makes Orlistat Effective
The fat-blocking mechanism provides tangible evidence that orlistat is working. When you eat meals containing fat whilst taking orlistat, you may experience oily stools or other gastrointestinal effects - these are actually signs the medication is blocking fat absorption as intended.
Generic orlistat 120mg costs £29.69 for 4 weeks with EDM10 discount, whilst branded Xenical costs £38.69 for the same period. Both work identically because they contain the same 120mg orlistat dose with the same fat-blocking mechanism.
Maximising Orlistat's Fat-Blocking Effect
To optimise how orlistat works, keep meals to around 15g fat each. Higher-fat meals mean more unabsorbed fat passes through your system, increasing side effects. Lower-fat meals still allow orlistat to work effectively whilst minimising gastrointestinal symptoms.
Take one 120mg capsule with each main meal containing fat, up to three times daily. If you skip a meal or eat a fat-free meal, you can skip that orlistat dose. The medication works for each individual meal rather than providing all-day fat blocking.
Clinical Evidence Behind Orlistat's Mechanism
Orlistat's lipase inhibition has been extensively studied in clinical trials. The consistent mechanism - blocking approximately one third of dietary fat - provides predictable support for weight management when combined with a reduced-calorie, lower-fat diet and increased physical activity.
This mechanism works best as part of a structured weight management programme. Orlistat supports calorie reduction from fat, whilst dietary changes and exercise address overall calorie balance and fitness.
