Why Orlistat's Mechanism Makes It Worth Buying

The Science Behind Orlistat's Fat-Blocking Action

Orlistat works through a targeted mechanism called lipase inhibition. In your digestive system, enzymes called lipases break down dietary fat so it can be absorbed into your bloodstream. Orlistat blocks these lipase enzymes, preventing approximately one third of the fat you eat from being digested and absorbed. This unabsorbed fat passes naturally through your body, reducing the calories absorbed from dietary fat.

Why "Approximately One Third" Matters

Understanding that orlistat blocks approximately one third—not all—of dietary fat is crucial for realistic expectations. This proven mechanism means that if you eat 15g of fat in a meal, around 5g will be blocked while 10g is still absorbed normally. This selective blocking supports weight management while allowing your body to absorb essential nutrients from the remaining dietary fat.

Choose Your Orlistat Option at EverydayMeds

Generic orlistat 120mg offers the most cost-effective option at £29.69 for a 4-week supply (84 capsules) with code EDM10. Branded Xenical 120mg provides the same fat-blocking mechanism at £38.69 for 4 weeks. For those preferring lower-strength treatment, Alli 60mg is available at £49.49 for 8 weeks. All options work through the same proven lipase inhibition mechanism.

How the Fat-Blocking Process Works Step-by-Step

When you take orlistat with a meal containing fat, the medication travels to your small intestine where fat digestion occurs. Here, orlistat binds to and inhibits pancreatic and gastric lipase enzymes. Without these enzymes functioning fully, approximately one third of dietary fat cannot be broken down into smaller molecules needed for absorption. This undigested fat continues through your digestive system and is naturally eliminated, reducing calorie intake from dietary fat.
