Overall, Lipozene is a decent weight loss supplement. But the problem with this it has only one mechanism of losing weight. And the diet pills or supplements that work best for a majority of people, work by different mechanisms. So, while lipozene is good at using fiber for weight loss and blocking fat (using glucomannan), it lags behind in using ingredients that provide energy and act as thermogenic metabolic boosters. We recommend Instant Knockout , which has Glucomannan as well as other ingredients that act as thermogenic metabolic boosters, and provides a better value for money. If you are specifically looking for fiber for weight loss, we recommend Smoothie Diet.
