Mifflin-St Jeor Equation

Definition

The Mifflin-St Jeor Equation is a formula used to estimate an individual's Basal Metabolic Rate (BMR), which is the number of calories a person needs to maintain basic bodily functions at rest.

Scientific / Technical Definition

The Mifflin-St Jeor Equation is a mathematical formula developed in the 1990s that calculates Basal Metabolic Rate (BMR) based on a person's weight, height, age, and gender. It is considered one of the most accurate equations for calculating daily caloric needs to maintain body weight.

Benefits

• Helps determine daily caloric needs for weight maintenance.
• Useful for tailoring diet plans for weight loss or gain.
• Assists in creating personalized nutritional and fitness plans.

Examples

• A nutritionist uses the Mifflin-St Jeor Equation to calculate BMR for a client to customize a meal plan.
• Fitness apps often incorporate the Mifflin-St Jeor Equation to estimate daily caloric expenditure.

Additional Information

• Importance: The Mifflin-St Jeor Equation is important for accurately assessing caloric requirements for individuals looking to maintain or modify their body weight.
