Moderate intake of carbohydrates generally does not lead to weight gain, excessive intake of carbohydrates will be converted into fat in the body, which will lead to weight gain. Carbohydrates enter the body, will be broken down into glucose under the action of the relevant digestive enzymes in the body, and then absorbed into the bloodstream through the small intestine, which can provide the body with the necessary energy. However, if the amount of carbohydrates eaten is too much, the body can convert the excess glucose into fat, which accumulates in various parts of the body, resulting in the manifestation of obesity. In order to avoid obesity, you should eat a balanced diet, pay attention to controlling the total energy intake, minimize the consumption of high oil, high sugar and other foods, and maintain appropriate physical exercise.
