The purpose of weighing every day is to monitor the change of weight and understand the progress of weight loss. However, the fluctuation of body weight is normal, which is influenced by many factors, including the amount of drinking water, the amount of excretion, and the condition of digestive system. Therefore, it is not accurate to judge the weight loss effect simply by the daily weight change. You may say that you haven't seen obvious weight loss for a long time, but after a month, you may suddenly find yourself losing a lot of pounds. This phenomenon is not metaphysical, but based on the following reasons:

1. fat burning process: in the process of losing weight, the body will first consume sugar and water in the body, not fat. So, when you start to lose weight, you may lose weight faster, but this is mostly the loss of water and sugar. Real fat burning may take longer, so it is normal not to see obvious weight changes.

2. Muscle growth: Fitness exercise or some aerobic exercise may increase muscle mass. Because muscle is denser than fat, weight may increase muscle while reducing fat, resulting in relatively slow overall weight loss.

3. Daily weight fluctuation: The weight will fluctuate normally during the day, because factors such as water intake and excretion will affect the weight. So weighing yourself every day may be affected by these fluctuations.

Therefore, it is suggested not to rely too much on the daily weight to judge the weight loss effect, but to pay attention to the overall changes of the body, including the changes of body shape, the improvement of physical fitness, the changes of clothes size and so on. Other more accurate indicators such as body fat rate and waist circumference can also be used as auxiliary indicators to evaluate the weight loss effect. Losing weight is a long-term process, and patience and persistence are the keys to achieving lasting results.
