Absolutely useless! What depresses the author is that in such a big country, we make so much fraud! Anti-science things are flooding so smoothly! First of all, passive exercise can never replace active exercise. Active exercise has a set of strict biochemical procedures, which is difficult for passive exercise to replace. The consumption of active exercise is 20 times that of quietness. What is the consumption of fat molecules? How to consume fat without oxygen? Is it useful? Testers will collapse if they collect oxygen consumption. Why does the advertisement not mention oxygen consumption at all? In addition, the temperature of fat dissolution in vitro can be arbitrarily controlled, and the temperature of fat dissolution is definitely higher than that in vivo, while the temperature in vivo is always above 36 degrees, depending on the activity of enzymes. The so-called experiment that newspapers can completely penetrate oil is ridiculous! Little planet wishes you health!
