TDEE CALCULATOR
TDEE is your total daily energy expenditure: an estimate of the calories you burn on an average day.
Start with your estimated TDEE. Choose maintenance, a moderate deficit for fat loss, or a small surplus for muscle gain.
It is a starting point. Use two to three weeks of progress to adjust your intake to your body and routine.
