Why is a TDEE calculator more useful than a BMR calculator?
BMR only tells you what you burn in a coma-like state. TDEE accounts for your actual lifestyle, exercise, and daily movement.
How do I choose the right activity level?
Be honest about your movement. A common mistake is overestimating activity levels, which leads to a TDEE calculation that is too high.
