This tool uses the Mifflin-St Jeor equation to calculate your Basal Metabolic Rate (BMR), then multiplies by an activity factor to get your Total Daily Energy Expenditure (TDEE).
What is TDEE?

How many calories should I eat to lose weight?
A safe calorie deficit is 500 calories below your TDEE, which results in approximately 1 pound of weight loss per week.
