Data Source and Methodology
All calculations are strictly based on the Cunningham Equation, a well-established method for calculating RMR in individuals with known lean body mass. Learn more about the Cunningham Equation.
The Formula Explained
\( \text{RMR} = 500 + 22 \times \text{Lean Body Mass (kg)} \)
Glossary of Terms
- Body Weight (kg): Total weight of the individual.
- Lean Body Mass (kg): The weight of a person's body excluding fat.
- Resting Metabolic Rate (RMR): The amount of energy expended while at rest.
How It Works: A Step-by-Step Example
For an individual with a lean body mass of 70 kg, the RMR is calculated as follows:
\( \text{RMR} = 500 + 22 \times 70 = 2040 \text{ kcal/day} \)
Frequently Asked Questions (FAQ)
What is the Cunningham formula?
The Cunningham formula is a method to estimate your Resting Metabolic Rate, considering lean body mass.
How accurate is the Cunningham formula?
The Cunningham formula is widely used for estimating RMR and is considered more accurate than other methods when lean body mass is known.
