Women tend to believe they look their best at values between 20 to 22 and men are usually satisfied with a BMI of 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. But if your BMI is more than that, you have to be carefull.... You may need some workout
If your BMI is between 23 and 25, you are not considered overweight by most people. But if your BMI is 26 or more, that's not good. But you knew that already.
