Try to maintain a similar body condition each time you measure. It's best to measure in the morning, after a bowel movement, on an empty stomach, as room temperature, food and water intake, and before and after exercise can significantly affect the results.
Don't measure daily, as this can easily affect your mood. Measuring every three days or once a week is better. While body fat scales aren't particularly accurate, they can be helpful in demonstrating fitness or weight loss results by analyzing the changes and trends over time (for example, overall muscle mass increases over a month).
