Understanding BMI and BMR

Body Mass Index (BMI) is a measure of body fat based on height and weight that applies to adult men and women. It is a simple tool to assess if you are at a healthy weight.

BMI Categories

  • Underweight: BMI less than 18.5
  • Normal Weight: BMI 18.5 to 24.9
  • Overweight: BMI 25 to 29.9
  • Obese: BMI 30 or greater

What is BMR?

Basal Metabolic Rate (BMR) represents the total number of calories your body needs to perform basic, life-sustaining functions (like breathing and circulation) while at rest. Knowing your BMR is the first step in creating a diet plan to lose, maintain, or gain weight.
