Frequently Asked Questions
Is BMI accurate for athletes?
Not always. Because muscle is denser than fat, athletes may have a high BMI but low body fat. In such cases, body composition analysis is a better metric.
Does BMI vary by age or gender?
The standard formula applies to adults (18+). However, interpretations can vary. Women naturally have more body fat than men, and older adults may have more body fat than younger adults with the same BMI.
What is the best time to weigh myself?
For the most consistent results, weigh yourself in the morning, after using the restroom and before eating or drinking.
