No, there are many authoritative documents abroad, and I have been paying attention to this aspect. The results show that nuts can lose weight. The main reasons for losing weight are as follows: first, the intake of unsaturated fatty acids and high-protein foods improves the thermal effect of food, which makes eating itself cause a lot of energy consumption. Second, eating nuts will increase people's satisfaction with food. Third, the dietary fiber content in nuts is high, which has the function of controlling weight. Fourth, some substances in nuts can enhance the sensitivity of insulin, thus increasing the body's metabolism of energy. Fifth, nuts contain granular substances and dietary fiber for storing fat, so people don't chew enough when eating nuts, which reduces the energy absorption rate in nuts. Sixth, many active substances in nuts, such as polyphenols, catechins, epicatechin and so on. , may have a certain weight loss effect.

This explanation is a bit too professional and difficult to understand, but it is indeed translated from authoritative foreign literature. Food in the human body is a very complicated transformation process, which can not be simply calculated according to the energy value, which is too one-sided.
