What Is Alli?
Alli is a brand name for the chemical orlistat. It is available over the counter in drug stores in the USA and the UK. It is also available as a prescription medication, often under the name of Xenical. Generic orlistat is also available in some countries.
How Alli Weight Loss Works
Alli weight loss effects have been demonstrated in many research studies and it is approved by the FDA as a weight loss aid. It works as a fat blocker, preventing the body from absorbing a certain percentage of the fats in our food.
At the usual dose of 60 mg three times a day it has been shown to block absorption of around 25% or one quarter of the fat that we eat. This increases to around 30% at a dose of 3 x 120 mg, which is not recommended without medical supervision. Beyond that there is very little added effect, so there is no point in taking more.
One study followed people taking alli in clinical trials over 12 months. Among the different groups of people, between 35% and 55% lost at least 5% of their body weight, which is a significant loss. About half of those people lost 10% of their starting body weight or more. These are very good results for clinical trials.
In addition, alli has been shown to reduce the risk of developing type 2 diabetes. Whether this is because of alli weight loss effects or whether there are other beneficial effects in alli has not been proved.
However, this does not mean that we can eat all the fat that we want and then take alli to prevent weight gain. It is important to be aware of the side effects of alli weight loss before starting to take it.
Side Effects Of Alli
The most common side effect of alli or orlistat is bowel disturbance. Alli blocks digestion of a lot of the fat that we eat and so that fat has to be expelled from the body in undigested form. The result is loose stools which may cause severe diarrhea in some cases. Many people also suffer from excessive flatulence.
These symptoms are worse when people begin taking alli. It seems that the body adjusts to it after a time. So you could help to avoid the side effects of alli by starting with a very low dose and gradually increasing.
However, the best way to avoid alli weight loss side effects is to eat less fat. That way, there is less undigested fat for the body to excrete. Eating less fat also helps with weight loss.
The manufacturers claim that alli or orlistat can improve your weight loss by up to 50%, assuming you are not simply taking alli so that you can eat more. It won't work if you do that. You do need to have some control over your food intake. But if this is true, it means that a person who loses 10 pounds without taking alli would lose 15 pounds in the same time with the same food intake if they add alli weight loss to the mix.
