Frequently Asked Questions
How is my daily calorie need calculated?
This calculator estimates your Basal Metabolic Rate (BMR) with the Mifflin-St Jeor formula from your age, height, weight, and sex, then multiplies it by an activity factor to get your Total Daily Energy Expenditure (TDEE) — your maintenance calories.
What is TDEE?
TDEE (Total Daily Energy Expenditure) is the total number of calories you burn per day, including your basal metabolism, digestion, and physical activity. It's the number you use as a baseline for weight loss, maintenance, or weight gain.
