What is Basal Metabolic Rate?
Basal metabolic rate (BMR) is the rate of energy expenditure per unit time by your body at rest.
Basal metabolic rate (BMR) Formula used by Keto Calculator
A popular way to calculated your estimated BMR is through the Harris-Benedict formula, which takes into account weight, height, age, and sex.
Females
BMR = 655 + (9.6 x weight in kg) + (1.8 x height in cm) – (4.7 x age in years)
Males
BMR = 66 + (13.7 x weight in kg) + (5 x height in cm) – (6.8 x age in years)
What is Body Mass Index?
BMI (Body Mass Index) is a widely used measurement that helps assess whether an individual’s weight falls within a healthy range based on their height. It provides a general guideline for weight categories such as underweight, normal weight, overweight, and obesity.
Body Mass Index (BMI) Formula Used By Keto Calculator
The index is calculated using the following formula:
BMI Categories and Their Meaning
Body mass index is classified into different categories based on ranges established by the World Health Organization (WHO):
- Underweight – BMI below 18.5
- Normal weight – BMI between 18.5 and 24.9
- Overweight – BMI between 25 and 29.9
- Obesity – BMI of 30 or higher
Body Mass Index (BMI) Calculation Charts for Adults
BMI calculations apply to both men and women, but body composition differences mean that BMI alone does not always give a full picture of health. Women naturally have a higher body fat percentage than men, which should be considered alongside BMI results.
The following BMI chart can help determine your weight category based on height and weight.

Alternative Health Indicators
Since BMI is not a perfect health measure, consider these additional indicators:
- Waist-to-Height Ratio (WHtR): A more accurate predictor of health risks.
- Body Fat Percentage: Provides a clearer picture of body composition.
- Muscle Mass Index: Useful for athletes and those with higher muscle mass.
