Lu Xiwei's 7-day fasting is a very classic detoxification and weight loss therapy in Switzerland. By fasting, you can detoxify, improve metabolic ability, and achieve the purpose of slimming and improving immunity. Deep detoxification of the whole body can rest and purify internal organs, improve immunity and delay aging. You can start your own self-healing ability and prevent and eliminate many chronic diseases. It is the most effective, healthful and quick-acting detoxification and weight loss regimen I have ever seen. I did it once in China, but I stopped eating it after using the product. I was not as hungry as I thought. My stomach sank and I was scared by the toxins discharged. Feces, urine, skin and sputum can all be felt by yourself!
