The Lipozene diet pill is manufactured by Obesity Research Institute. You may have heard of them - they previously marketed similar products under the names Fiberslim and Propolene.

The central ingredient in Lipozene, is a substance called glucomannan. And this is the same substance that was used in Obesity Research Institute's prior diet products. So first, you need to take a good look at what exactly is glucomannan.

Now, there are clinical studies which confirm that glucomannan lowers blood-fat levels, and levels of the "bad" cholesterol (LDL). There is also some confirmation that consuming glucomannan with water before a meal, will give you a full feeling (the idea being that you will then eat less).
