Understanding Your BMI Results

  • Underweight: BMI is less than 18.5
  • Normal weight: BMI is 18.5 to 24.9
  • Overweight: BMI is 25 to 29.9
  • Obese: BMI is 30 or more

If your BMI indicates you are in the overweight or obese category, you may want to explore our Weight Loss Diet Guide or start a HIIT Program.

The Limitations of BMI

While BMI is a widely used screening tool, it's important to understand its constraints. BMI does not distinguish between muscle mass and body fat. Athletes with high muscle mass may be categorized as "overweight" despite having very low body fat percentages.

Health Implications

Maintaining a BMI within the "Normal" range is associated with lower risks of cardiovascular disease, type 2 diabetes, and certain cancers. However, health is multi-factorial, and BMI should be viewed alongside other metrics like body fat percentage and waist circumference.
