There are two reasons: first, because the source of water in our body is not only water, drinks and soup, the food we eat contains water to a greater or lesser extent, and dieting also reduces the intake of this part of water. Some people even drink less water while losing weight, which makes the water shortage more serious. Secondly, because many diet pills and tea excrete some water at the same time, the way of Chinese medicine to lose weight is often to detoxify the body to achieve the purpose of losing weight, and the discharge of toxins also requires the participation of water. Some extreme ways to lose weight, such as taking laxatives, diuretics, sweating drugs, etc., will cause a lot of water loss.

Be sure to drink plenty of water during weight loss. Drinking more water will not make people fat, but it can replenish the water lost in metabolism. Drinking more water is also beneficial to the discharge of waste, especially when you lose weight faster or sweat too much because of strenuous exercise. Especially in summer, when you lose weight, the weather is hot and you sweat a lot. If you don't replenish water in time, your weight may drop temporarily, but eventually it will cause physical discomfort such as heatstroke because of the dysfunction of body fluids to regulate body temperature.
