Why can I lose weight by drinking L-carnitine coffee powder? Mainly because the L-carnitine and caffeine contained in coffee powder can promote fat metabolism, especially L-carnitine, which exists in human body. If there are more L-carnitine in the body, they are what everyone calls lean physique. If there is less L-carnitine in the body, people are likely to get fat even if they drink boiled water. It is precisely because it can promote the metabolism of thick fat layer, convert it into free fatty acids, and further excrete it through human urine and sweat, so people will gradually lose weight after drinking for a period of time. Of course, if you want to lose weight better, I suggest you keep exercising for more than 30 minutes every day and drink L-carnitine coffee powder at the same time. The above is my personal answer about the topic that L-carnitine coffee powder can lose weight. It should be reminded that although it can help people to have a beautiful figure, it actually has some side effects. For example, if people eat too much, they will be too excited to sleep, and their weight may rebound immediately after stopping eating.
