Explanation:

A person with a mesomorphic type of body would have less fat than muscle. They can easily lose weight and gain muscles. They are usually strudy and thus have the ideal athletic build.

BMI or body mass index is a measure used to determine whether a person has the right weight considering their height. It can help determine whether one is obese because if the BMI is too high, it would mean that the person is too heavy or overweight considering their height. Being too heavy for your height could be detrimental to the growth and development of your bones and other factors that contribute to health.

Body composition is tricky to measure when it comes to accuracy and so professional tools are necessary. Although there are other methods used like calculating it based on the person's height and body measurements, this would only give you an approximate.
