Frequently Asked Questions

What is BMR?
BMR (Basal Metabolic Rate) is the number of calories your body needs to maintain basic life-sustaining functions like breathing, circulation, and cell production while at rest.
How is BMR calculated?
BMR is commonly calculated using the Mifflin-St Jeor or Harris-Benedict equation, which factors in gender, age, height, and weight.
How can I increase my BMR?
Building muscle through resistance training is the most effective way. Muscle tissue burns more calories at rest than fat tissue. Adequate sleep and regular meals also help.
