@swaefit2: The most commonly used formula to estimate Basal Metabolic Rate (BMR) is the Mifflin-St Jeor equation: For males: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5 For females: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161 Once you have the BMR, you can adjust it based on activity level using the Harris-Benedict equation or other methods. #personaltrainer #fitnessjourney #health #az #scottsdale #weightloss #bmr #caloriedeficit #caloriesurplus
