What does Liz's BMI of 21 indicate about her weight status?

A BMI (Body Mass Index) of 21 falls within the range considered healthy. BMI is a widely used screening tool that categorizes individuals based on their weight relative to their height. The general classifications are as follows: underweight (BMI below 18.5), normal or healthy weight (BMI from 18.5 to 24.9), overweight (BMI from 25 to 29.9), and obese (BMI of 30 or above).

Since Liz's BMI is 21, it clearly falls into the "healthy weight" category, indicating that her weight is appropriate for her height according to standard health guidelines. This suggests a lower risk of weight-related health issues and generally signifies good overall health concerning weight status. In contrast, other weight categories either indicate a need for weight loss or nutritional intervention, making "healthy" the accurate description of her weight status in this scenario.
