What is BMI and Why Does It Matter? Use our BMI Calculator

By Chef LaLa

BMI is a numerical value calculated using your weight and height. Using the Chef Nourish BMI Calculator provides a reasonable assessment of body fat for most people and helps categorize weight status. While BMI is not a direct measure of body fat, it serves as a screening tool to identify potential weight issues that could impact your health.


Understanding your BMI can help you:



  • Assess your weight status in relation to health risks

  • Set realistic and personalized nutrition goals

  • Track your progress over time

  • Make more informed decisions about your meal choices


Here's guidance on how frequently to calculate your BMI:


For most healthy adults maintaining a stable weight, calculating BMI once or twice per year is typically sufficient. This frequency allows you to monitor gradual changes without becoming overly focused on numbers.


If you're actively working on weight management goals, checking your BMI quarterly (every 3-4 months) can help track progress while still focusing on sustainable habits rather than short-term fluctuations.


For individuals with certain health conditions where weight management is critical, such as diabetes, heart disease, or hypertension, your healthcare provider might recommend more frequent BMI calculations as part of your overall health monitoring plan.


During significant life changes that might affect your weight—pregnancy, menopause, recovery from illness, or new medication regimens—discussing appropriate BMI monitoring with your healthcare provider is advisable.


Remember that BMI has limitations. It doesn't distinguish between muscle and fat, doesn't account for body composition differences across ethnicities, and may not be appropriate for athletes or older adults. For a more comprehensive health assessment, consider combining BMI calculations with other measurements like waist circumference, body fat percentage, or fitness tests.


The goal of periodic BMI calculations should be gaining helpful information about your health trajectory, not creating anxiety or unhealthy fixations on numbers. If you find yourself calculating BMI excessively or feeling distressed about the results, consider speaking with a healthcare professional about developing a healthier relationship with body measurements.
