L-carnitine is an amino acid, which can transform fat into energy, and red meat is the key component. If people who lose weight eat it, it will simply cause excitement, and there will be situations such as excessive sex, nervous energy and impulsive mood, which will probably lead to cerebrovascular diseases, such as cerebral infarction and cerebral hemorrhage. Therefore, this does not have a weight loss effect, but it will endanger human health. If you want to lose weight, keep a good diet.
