Why Is My Weight Heavier in the Morning Than in the Evening?

The weight in the morning is lighter than in the evening because there is no food or water intake during the night, but the body continuously consumes energy and evaporates water through metabolism. However, this situation is not always the case. Weight is constantly changing and is closely related to factors such as food intake, water intake, bowel movements, urination, sweating, and physical activity. It is not meaningful to measure weight multiple times a day, whether for weight loss or weight gain. The trend of weight change can only be determined through long-term observation. The weight changes measured within a day are not likely to be significant and cannot represent the trend of weight gain or loss. Therefore, it is normal for the weight in the morning to be lighter or heavier than in the evening. Everyone has different daily routines and different times to weigh themselves. For individuals, it is recommended to weigh regularly during weight loss, and each time should be at the same time, such as after waking up or taking a shower, and after using the toilet, to ensure more accurate measurements. To maintain weight, it is recommended to weigh once a day to detect any changes in weight promptly and take appropriate measures. The correct weighing posture is to try to keep all influencing factors consistent during each weighing and avoid any potential interferences.
