Frequently asked questions
What is TDEE?
Total Daily Energy Expenditure is an estimate of all the calories you burn in a day, combining your resting metabolism (BMR) with activity, exercise, and digestion. It approximates your maintenance calories.
How accurate are activity multipliers?
They are rough estimates. Studies show people commonly overestimate activity. If the number seems high, compare your actual weight trend over 2–3 weeks against your intake and adjust.
Should I eat my TDEE to maintain weight?
In theory, yes — eating at estimated maintenance should keep weight roughly stable. In practice energy needs vary day to day, so treat it as a starting estimate and adjust based on real-world trends.
