What is BMR?
Basal Metabolic Rate (BMR) is the number of calories your body needs to perform basic life-sustaining functions like breathing, circulation, and cell production while at complete rest.
What is TDEE?
Total Daily Energy Expenditure (TDEE) is the total number of calories you burn each day, including your BMR plus all physical activity. This is the number you should use when planning your diet.
The Mifflin-St Jeor Equation
This calculator uses the Mifflin-St Jeor equation, which is considered the most accurate formula for estimating BMR according to the American Dietetic Association. It was developed in 1990 and has been validated in numerous studies.
Important Notes
- Individual metabolism can vary by ±10% from calculated values
- Consult a healthcare provider before starting any diet
- Never consume less than 1200 calories/day without medical supervision
- For weight loss, a deficit of 500 cal/day typically leads to ~0.5 kg/week loss

Quick answer
Medikle Calorie Calculator
The Medikle Calorie Calculator estimates daily calorie needs by calculating BMR and adjusting for activity level, then gives targets for maintaining, losing, or gaining weight.
How calorie needs are estimated
This tool uses the Mifflin-St Jeor equation to estimate resting calorie needs, then multiplies that estimate by activity level to calculate total daily energy expenditure.
- BMR estimates calories used at rest.
- TDEE estimates calories used across a full day.
- Goal targets adjust TDEE upward or downward for weight change.
How to use the result
Treat the result as a starting estimate. Track weight, energy, and hunger over two to four weeks, then adjust intake carefully. Very low calorie diets should be supervised by a qualified clinician.
