An athlete or body builder is often considered overweight or obese according to their higher BMI calculations. Fitness level is overlooked in BMI calculations. A muscular man has more muscle mass as muscle is denser and heavier than fat so it makes his BMI higher.

But his weight is healthy regarding his fitness but according to BMI calculations his body weight is unhealthy, and he is overweight or obese. Higher muscle mass composition does not make you overweight or obese because it is fat and not muscle which is unhealthy.

?    Height can be responsible for high BMI

BMI calculations are not acceptable when height is considered. BMI calculations are obtained by dividing a person?s weight by square of his height. According to Nick Trefethen , a professor at Oxford University, Square of height in BMI calculations exaggerates weight in tall people making them feel fat and under exaggerates weight in short people making them feel thin. So more height can also be reason for higher BMI.

?   Unhealthy Eating habits

Your eating habits play a major role in your weight. Consuming unhealthy food like junk foods and foods with unnecessary sugars increase your BMI and obviously you will fall in overweight and obese category. Eating without having appetite and consumption of unhealthy food leads toward higher BMI.

Inheritance patterns in family due to mutation in single gene are also responsible for obesity. This gene is?MC4R?that encodes melanocortin 4 receptor.

?    Age

Due to anatomical, structural and body compositional changes with age body mass index also gets high. It becomes more difficult to maintain weight with age.?Onward age 30?stature declines faster in women than men. Decline in stature is also responsible for increase in BMI with age.

According?to studies?body fat content in non exercising women at age of 17 to 20 years with BMI 25 increased from 30 percent to 36 percent for those ages 40 years or older.??With age lean body mass also decreases. So aging is responsible for higher BMI as well.
