About this calculator
Overview
Basal Energy Expenditure (BEE) is the amount of energy (in calories) your body needs to maintain basic physiological functions while at complete rest. These functions include breathing, blood circulation, cell production, and temperature regulation. The Harris-Benedict equation is one of the most established methods for estimating this baseline.
💡
Pro Tips
Measure your weight first thing in the morning for the most consistent results.
BEE is different from BMR, though the terms are often used interchangeably in casual settings.
Remember that any activity, even standing or walking, requires calories *above* your BEE.

Fun Facts
"BEE accounts for about 60-75% of your total daily energy expenditure (TDEE)."
"Muscle mass is more metabolically active than fat, meaning it increases BEE."
"BEE typically decreases as you age due to a decrease in lean body mass."
"The brain alone uses about 20% of your basal energy."
