Common mistakes
These are the interpretation mistakes that usually waste time or produce the wrong result.
- BMI, BMR, and TDEE are different measurements and should not be interpreted as one number.
- These outputs are for everyday reference only and do not replace diagnosis or treatment decisions.
- Choosing an activity level that is too high can inflate TDEE and weight-loss calorie targets.
