How Body Mass Index is calculated
Body Mass Index (BMI) is calculated from a person’s weight and height. The standard equation is BMI = kg/m2, where kg is body weight in kilograms and m2 is height in meters squared.
Learn more from the CDC BMI reference.
How BMR is calculated
Basal Metabolic Rate (BMR) estimates the energy a body uses at rest. NutriLens AI may use established predictive equations that consider weight, height, age, and sex to estimate energy needs.
Nutrition targets are estimates and can vary by individual metabolism, health conditions, medications, and activity level.
How NutriLens AI’s Nutrition Grade is calculated
The Nutrition Grade summarizes the estimated quality of a food or meal using calories, macronutrient balance, fiber, sugar, sodium, fat, and ingredient quality signals when available. The result is translated into an easy-to-understand letter grade.
| Grade | Score range |
|---|---|
| A+ | 90+ |
| A | 80-89 |
| B+ | 70-79 |
| B | 65-69 |
| B- | 60-64 |
| C+ | 55-59 |
| C | 50-54 |
| C- | 40-49 |
| D | 0-39 |
