function theory is as follows

1. Restrain the activity of lipase in stomach and intestinal canal to enable the fat in the taken food not to be absorbed by the body. This effect is shown in the form of defecate with fat (oil) nature, which means people could excrete the equal quantity of fat as that has been taken

2. Improve the metabolism and basic metabolism ratio (BMR) of fat, which means to increase the consumption of human body energy. The body fat would be broken up into heat, carbon dioxide and water. This product could not only reduce the redundant fat, but could also supplement many kinds of amino acid and trace element such as copper, iron, phosphorus, calcium, potassium, zinc and selenium.
