Mifflin-St Jeor Protocol: Calibrated for modern metabolic prediction with 100% mathematical precision.

Metabolic Expenditure Audit

The institutional engine for total daily energy expenditure (TDEE) assessment. Calibrated using the Mifflin-St Jeor Equation, this tool provides a high-precision verification of biological energy requirements. By synthesizing basal metabolic rates with physical activity multipliers, it defines the mathematical boundary for weight maintenance, hypertrophy planning, and caloric deficit trajectories.

How to use

  • Select your biological sex. This dictates the specific metabolic baseline constants utilized in the equation.
  • Enter your current age, weight (in kg), and height (in cm) with absolute precision.
  • Select your Activity Level. Be honest, overestimating your activity level will artificially inflate your daily calorie allowance and stall weight loss.
  • Review the 'Daily Results' matrix to see your exact Maintenance ceiling.
  • Follow the specific caloric target that aligns with your personal goal (Maintenance, Weight Loss, or Extreme Loss).

The Mifflin-St Jeor Metabolic Algorithm

The clinical gold standard for predicting resting metabolic rate, widely adopted by global dietitians for its superior accuracy.

BMR (Male) = (10 × weight) + (6.25 × height) - (5 × age) + 5 BMR (Female) = (10 × weight) + (6.25 × height) - (5 × age) - 161 Total Daily Energy Expenditure (TDEE) = BMR × Activity Multiplier

Understanding Your Daily Calorie Needs

Managing your calories is the foundation of healthy weight management. By understanding your Total Daily Energy Expenditure (TDEE), you can make informed decisions about your diet and exercise. This Calorie Tool provides a high-precision calculation of your daily energy needs. For a broader understanding, you may also want to explore Linear Equation Solver.

1. The Components of Burn

BMR (60-75%)

The energy required for vital functions at rest. This is the baseline energy needed to stay alive. Many users also utilize this nepse estimator alongside this analysis.

TEF (10%)

The Thermic Effect of Food. The energy used to digest and process the nutrients you consume. You can gain deeper insights by using LCM & GCF Calculator.

Frequently Asked Questions

The original Harris-Benedict equation was created in 1919 and tends to overestimate caloric needs by about 5-10%. The Mifflin-St Jeor equation, developed in 1990, accounts for modern lifestyle changes and is clinically proven to be the most accurate predictive formula for today's population.
No. Dropping below 1,200 calories per day for women or 1,500 for men is medically classified as a very-low-calorie diet (VLCD). It can cause severe muscle catabolism, gallstones, malnutrition, and a long-term slowing of your basal metabolic rate.
Yes. As your body mass decreases, the amount of energy required to sustain it also decreases. You should recalculate your TDEE for every 3 to 5 kilograms of weight lost to ensure your caloric deficit remains mathematically intact.
No. If you accurately selected your 'Activity Level' (e.g., 'Moderately Active'), the calculator has already factored your exercise into the final number. 'Eating back' exercise calories on top of this will erase your fat-loss deficit.
Due to hormonal differences, men naturally carry a higher percentage of metabolically active lean muscle mass and lower essential fat percentages than women. Muscle tissue burns significantly more calories at rest, which is reflected in the differing mathematical constants.
A 500-calorie daily deficit equals a 3,500-calorie weekly deficit. Since 1 kilogram of body fat contains roughly 7,700 calories, this protocol mathematically forces your body to burn exactly 0.45 kg (1 pound) of pure fat every week.

Calories & Nutrition FAQ

How many calories do I need per day in Nepal?

This depends on your activity level. A sedentary worker in Kathmandu might need 1,800-2,000 calories, while an active trekker could require over 3,000 calories.

How many calories should I cut to lose 1kg a week?

To lose 1kg of fat, you need a deficit of roughly 7,700 calories. A daily deficit of 500-700 calories is generally recommended for safe, sustainable weight loss.

Do calories from Dal Bhat count differently?

A calorie is a unit of energy, but nutritional quality matters. Dal Bhat is a balanced meal providing sustained energy, making it superior to processed snacks.

Should I track my exercise calories separately?

Our calculator includes an activity factor (TDEE). While exercise burns calories, most people overestimate the burn; tracking through TDEE is more accurate.

What is the minimum calories I should eat daily?

Generally, men should not go below 1,500 and women below 1,200 calories without medical supervision to ensure adequate nutrient intake.
