When choosing the best TDEE (Total Daily Energy Expenditure) calculator to accurately calculate your daily calorie needs, there are a few things to consider. First and foremost, I recommend choosing calculators that take into account as many factors as possible: not just your age, gender, weight, and height, but also your activity level, metabolism, and body fat percentage. Calculators that only offer standard formulas can be helpful, but you’ll get a more accurate result if the tool takes your unique characteristics into account as well.
