BMI 25 to 29.9 = overweight

The Clinical relevance of BMI:

BMI is an indicator for total body fat in many individuals. So it is considered as an indicator of health risk. BMI is used by healthcare professionals to screen for overweight and obese person. The BMI is used to assess a person’s health risks associated with obesity and overweight.

For example person's with a high BMI are at risk of:

high blood cholesterol or other lipid disorders
type 2 diabetes
heart disease
high blood pressure
certain cancers
gallbladder disease
sleep apnea and snoring
premature death
osteoarthritis and joint disease

BMI, however, is one of the best tools that are used to calculate healthy risk. Other factors such as blood pressure, cholesterol level, blood sugar level, family history of heart disease, age, gender, waist circumference, level of physical activity, menopause status, smoking status etc. are also taken into consideration while assessing health risk.

But Question Is BMI applicable for all?

For most of the people, BMI is used to provide a good measure of obesity. But BMI is not applicable to provide actual information about body composition like amount of muscle, bone, fat, and other tissues.

BMI is a more accurate measure of body fat for some persons but not for others. For example, Khali is very muscular may fall into the “overweight” category when they are actually healthy and very fit. Rohit with a very low body fat percentage could have the same BMI score as someone who is overweight.

Similarly, an elderly and frail one person may be in the normal weight category when He has little muscle mass and a high percentage of body fat.

BMI tool, when used for the children and adolescents who are in growing stage, those with large body frames or petite builds, pregnant women and highly muscled individuals thus need to be assessed and interpreted carefully.
