Free BMI & BMR Calculator
Know Your Body – Know Your Numbers
At FitNest by NN, we believe the first step toward healing through nutrition is understanding how your body works. That’s why we’ve created a free BMI (Body Mass Index) and BMR (Basal Metabolic Rate) calculator — designed to give you instant insights into your current health status and daily calorie needs.
What is BMI (Body Mass Index)?
BMI is a quick way to assess your weight in relation to your height. It gives you a general idea of whether you’re underweight, normal weight, overweight, or obese.
Why BMI Matters
- Assesses your health risk related to body fat.
- Indicates your risk for chronic conditions like PCOS, diabetes, heart disease, and hormonal imbalance.
- Helps track your progress over time.

What is BMR (Basal Metabolic Rate)?
Your BMR is the number of calories your body needs to perform basic life functions like breathing, digestion, and circulation — even when you’re at complete rest.
Why BMR is Important
- Helps you determine how many calories you burn daily
- Crucial for creating effective weight loss or gain plans
- Prevents undereating or overeating
- Guides your ideal daily caloric intake for healing, hormonal balance, and energy.
