Why does my weight seem to change so much?

Is daily weight fluctuation normal?

If you keep a careful eye on your weight every day, especially while you’re on a weight gain or weight loss journey, you might have these questions and many more. Small weight changes are expected.

According to studies, the average person can lose or gain two to eight pounds in just a few days. Weight is often highest at the start of the week and lowest at the end.

But does noticing a varied number on the scale make you ponder if weight fluctuation is bad?

So, everyday variation is typical under certain conditions, but it only sometimes characterizes your success. You will see changes in your weight the following day if you consume a large dinner the previous evening. The components that make up your everyday weight are numerous.

Therefore, if you’re wondering how much weight fluctuates in a day per kg, the answer is 1-2 kgs in an adult body, per research.

What are the reasons for Weight Fluctuation?

Exercise, water intake, consumption of sodium and carbs, alcohol, bowel movements, sleep, hormones, and binge eating are some elements that might contribute to daily weight swings or cause weight fluctuation over a month.

Additionally, your body will store additional calories as fat if you routinely exercise. That occurs when your calorie intake exceeds your calorie expenditure, which may also cause changes in your weight.

Let’s examine some of the elements that affect weight fluctuation.


It should come as no surprise that a significant portion of your daily weight is determined by water. Is water-related weight fluctuation harmful? Only sometimes. Heavy consumption of processed or salty foods is typically the cause of water retention. Because sodium makes you thirsty, you drink more water than your body needs. You can reduce weight fluctuation by eating less salty food, but remember that this is merely water weight.


This is one of the answers to how to stop weight fluctuation. Alcohol can slow your metabolism, cause water retention, and make you bloated. It contains a lot of calories and slows down metabolism, which causes your body to retain fat and fluctuate in weight. Additionally, alcohol reduces your body’s ability to burn fat and raises your risk of overindulging in salty foods.


When awake late at night, we frequently indulge in a large meal or binge on food high in calories, fat, and carbohydrates. According to studies, sleep-deprived people tend to eat more, probably because their hormone ghrelin levels are higher. If this becomes a habit, people will acquire weight quickly and see frequent weight fluctuations over a month.

Menstrual cycle

If you’re attempting to calculate how much weight fluctuates in a day (in kilograms), you might want to consider it from a different angle during your menstrual cycle. Due to salt and water retention, weight gain is typically prevalent during and around the menstrual cycle. Women who experience this period may also swell, raising their weight by up to 4 pounds. They may also experience an increased appetite, leading to a high-calorie intake.
