Losing weight quickly without eating at night may only be aimed at a very small number of people, but the disadvantages outweigh the benefits. The three nutrients that produce energy are protein, fat and carbohydrate. Fat 1g can generate 9 kilocalories, and protein and carbohydrate 1g can generate 4 kilocalories. Eating less can reduce the intake of carbohydrates, which can reduce the intake of energy, but eating more vegetables will increase the intake of fat, leading to higher energy, which will not only fail to achieve the goal of losing weight, but will make the nutritional intake unbalanced and unhealthy. Zhao Yanmei is already very thin and doesn't need to lose weight.
