The tdee calculator is a tool that helps estimate your total daily energy expenditure, taking into account your level of physical activity, age, weight, gender, and other parameters. However, despite its popularity, it does not always reflect your actual calorie expenditure. The TDEE calculation is based on average data and general formulas, which makes it quite approximate. For example, metabolism can vary significantly among people, and even with the same external data, two people can burn calories differently. In addition, the calculator does not take into account many factors, such as hormonal changes, health status, or dietary habits. Therefore, for a more accurate assessment of your actual energy expenditure, it is worth considering additional methods, such as body composition analysis or the use of fitness trackers. The TDEE calculator can be a useful guide, but it does not provide 100% accuracy and cannot completely replace an individual approach.
