🔥 Calorie Calculator (BMR/TDEE)

Daily calorie needs using the Mifflin-St Jeor formula: basal metabolic rate, activity-adjusted burn, and calorie targets for losing, maintaining, or gaining weight.
Basal Metabolic Rate
Weight loss (~-20%)
Maintenance (TDEE)
Weight gain (~+15%)
The Mifflin-St Jeor formula is one of the most accurate ways to estimate basal metabolic rate. This is a guideline, not medical advice.
