According to my BMI, I'm a bit too short for my weight. Women tend to believe they look their best at Body Mass Index (BMI) values between 20 to 22. Men are usually satisfied with a BMI of between 23 to 25. If your BMI is between 17 to 22, your life expectancy is longer than average. You don't need to lose weight.
For boys and girls between 2 and 7 years old, the average BMI is somewhere between 16 and 17 as of 2010, depending on age and gender, but the range of what is healthy is broader than this. For example, a 5-year-old boy is considered healthy with a BMI from 13.8 and 17.
