Alli: Our #4 Favorite Weight Management Pill


Alli, pronounced “AL-eye”, is a non-prescription weight management product that is unique in the weight loss industry.  It is the first over the counter diet pill to become legally available in the United States which contains an ingredient sold as a prescription drug in higher doses.  This substance is FDA approved and has substantial research to support its use as a part of a healthy weight loss diet.

Why Use Alli?

Alli is a diet pill developed for individuals who find it difficult to control the amount of dietary fat they consume in the average day.  To use it correctly, the dieter must follow a reduced fat diet.  This pill works as a fat blocker.  This means that its effects inhibit the body’s ability to absorb fat.  This way, it is sent through the body undigested and the calories from those fats don’t affect the user’s intake total.

To use it correctly, the dieter must follow a reduced fat diet. This pill works as a fat blocker.

Alli Ingredients

Alli is based on a single active ingredient.  It is a proven fat blocker and is also sold at a higher dose as a prescription drug.  The ingredient is called Orlistat. It is the active ingredient in the prescription medication called Xenical.  The prescription dose for Orlistat is usually 120 milligrams.  However, Alli contains only 60 milligrams of the drug and can therefore be sold as an over the counter pill.

Alli is meant for use by people who have a BMI of 25 to 29.9.  Unlike its prescription strength counterpart, this is not considered to be an obesity treatment. Instead, it is a diet pill to help overweight dieters to better control their weight through healthy diet and exercise.

Alli Precautions

Many people mistakenly believe that because Alli is an over the counter diet pill, this means that it is safe and appropriate for everyone and is not associated with severe side effects. When taken according to its directions, many healthy adults will be able to safely use this product without any unpleasant effects. It is meant for dieters aged 18 years or older and must be used in the same way as its prescription-strength counterpart.

Without following a reduced-fat diet and regular exercise program, using Alli could easily lead to unpleasant side effects that can be very uncomfortable or even embarrassing. Many of this product’s side effects require frequent trips to the bathroom, so new users should be aware of this potential effect before they start using these pills.

It is also important to note that using products containing Orlistat can increase the risk of liver injury. Symptoms of liver injury include itching, loss of appetite, light colored stool, brown urine, and yellowing of the skin and or/eyes, among others.

It is also very important to take care in maintaining proper nutrition while taking Alli. As this product reduces the fat absorption in the body, it also means that it reduces the absorption of fat-soluble vitamins and minerals. Speak with a doctor regarding whether or not you should be supplementing certain among those vitamins and minerals in order to avoid deficiency.

Due to the many risks associated with taking products containing Orlistat, it’s a very good idea to speak with your doctor before starting the use of Alli, despite the fact that it is a non-prescription pill.
