Why Orlistat's Fat-Blocking Action Gets Results

The Science Behind Orlistat's Fat-Blocking Mechanism

Orlistat works by inhibiting lipase enzymes in your digestive system. These enzymes normally break down dietary fat so your body can absorb it. 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 body, reducing the calories your body stores as weight.

How Fast Does Orlistat Start Working?

Orlistat begins working with your very first dose. Within hours of taking your capsule with a fat-containing meal, the medication starts blocking lipase enzymes in your gut. You may notice the effects - unabsorbed fat in your stools - within 24-48 hours. This immediate action proves the fat-blocking mechanism is working effectively. At EverydayMeds, you can start with orlistat 120mg for £29.69 per month or Alli 60mg for £26.09 per month using code EDM10.

Why Fat-Blocking Works Better Than Other Approaches

Unlike appetite suppressants that work on your brain, orlistat works locally in your gut without being absorbed into your bloodstream. This targeted action means it specifically addresses dietary fat - often the highest calorie component of meals. When you block approximately one third of fat absorption, you're removing a significant source of excess calories that would otherwise be stored as weight.

Choosing Your Orlistat Strength - 60mg vs 120mg

Alli 60mg blocks a smaller proportion of dietary fat compared to prescription-strength orlistat 120mg. Both work via the same mechanism, but 120mg provides stronger fat-blocking action. Generic orlistat 120mg offers the best value at £29.69 for 4 weeks, while branded Xenical 120mg costs £38.69 for the same period. Alli 60mg at £26.09 for 4 weeks suits those preferring lower-strength treatment. All prices include 10% off with code EDM10.

Supporting Your Fat-Blocker With the Right Diet

Orlistat works best when you limit fat intake to approximately 15g per meal. This maximises weight loss while minimising side effects. The medication doesn't block carbohydrates or protein - only dietary fat. When combined with a reduced-calorie, lower-fat diet, orlistat's fat-blocking mechanism delivers optimal results. Higher fat meals will increase side effects as more unabsorbed fat passes through your system.
