Fat-blocking medications have become a reliable option for people seeking safe, clinically proven weight-loss support. Among the most widely used options are Alli, Xenical, Orlistat, and Orlos 60mg weight loss capsules. These treatments work by preventing your body from absorbing a portion of dietary fat, allowing users to lose weight more steadily while maintaining a calorie-controlled lifestyle. This guide explains how these tablets work, how they differ, and what results you can expect.
How Fat-Blocking Medications Work
All of these treatments contain orlistat, the active ingredient responsible for blocking the absorption of up to 25% of the fat you eat.
When taken with meals, orlistat attaches to digestive enzymes in the gut, preventing them from breaking down fat. The undigested fat then passes naturally through the body instead of being stored.
Key benefits of fat-blocking medicines include:
Reduces overall calorie intake
Helps encourage healthier eating habits
Supports gradual, consistent weight loss
Works only in the digestive tract, not the bloodstream
Alli: The Lower-Strength, Over-the-Counter Option
Alli (60mg orlistat) is designed for adults looking for a gentle yet effective start to medically supported weight loss. It contains half the strength of prescription orlistat, making it suitable for those who want a milder treatment.
Benefits of Alli:
Available without a prescription
Helps block around 25% of dietary fat
Ideal for beginners or those seeking a low-dose option
Xenical: The Prescription-Strength Version
Xenical (120mg orlistat) is the prescription-strength form of the medication. It provides stronger fat-blocking effects and is often recommended for individuals with a higher BMI or those seeking faster results under medical supervision.
Benefits of Xenical:
Double the strength of Alli
Stronger fat-blocking effectiveness
Suitable for people with more weight to lose
Orlistat: The Active Ingredient Used in Many Brands
Orlistat is available as both a branded and generic medication. Regardless of branding, the active ingredient remains the same, offering effective fat-blocking results at either 60mg (OTC) or 120mg (prescription) doses.
Why people choose orlistat:
Clinically proven for weight loss
Works directly in the digestive system
Can improve weight-related health conditions over time
Orlos 60mg Weight Loss Capsules: A Popular OTC Alternative
Orlos 60mg works in the same way as Alli, offering an over-the-counter dosage for those wanting accessible weight-management support. It is often chosen as a more affordable option without compromising effectiveness.
Benefits of Orlos 60mg:
Fat-blocking formula identical to other 60mg versions
Helps reduce calorie intake per meal
Supports long-term weight-loss programmes
Who Are These Medications Suitable For?
These fat-blocking treatments are typically recommended for adults who:
Have a BMI of 28 or higher
Are committed to a calorie-controlled diet
Prefer tablet-based, non-hormonal weight-loss options
Want to reduce fat absorption naturally without injections
They are especially helpful for individuals who struggle with high-fat diets or portion control.
Expected Results
Users who take orlistat consistently—paired with healthier eating—often experience:
Steady weight loss over several weeks
Reduced inches around the waist
Better tirzepatide long-term weight stability
Improved confidence and energy levels
Results vary depending on diet quality, adherence, and lifestyle changes.
Potential Side Effects
Because these medications affect how fat is processed, some users may experience temporary digestive changes, such as:
Oily stools
Increased bowel movements
Mild stomach discomfort
These effects typically improve as users reduce fatty foods and adapt to the treatment.
Conclusion
Alli, Xenical, Orlistat, and Orlos 60mg capsules provide a safe and effective way to support gradual weight reduction by blocking the absorption of dietary fat. Whether you prefer a prescription-strength treatment or an accessible over-the-counter option, these medications can help you achieve long-term weight-loss goals when combined with mindful eating and consistent lifestyle habits.
