Did you know that liver cleansing can help you lose weight? Many people are unaware that the liver is highly instrumental in the breakdown of fat. In every respect, the liver is just as essential to weight loss as are the intestines and the stomach. The liver produces bile, which is used by the digestive system in the breakdown of fat. When you cleanse your liver, you help it promote the production of bile, which will in turn assist your body in metabolizing fats.
