How accurate is this?

The Mifflin-St Jeor equation is the most validated formula for estimating BMR in non-athlete adults, with roughly 10% variance. Use this number as a starting point, not a ceiling. Track your intake for 2 weeks, observe your weight trend, and adjust by 100–200 cal if the results don't match expectations.
