May I have a thinner body?

A better question. A better question would be: do I need to have a thinner body? Find a body mass index calculator on the internet. Plug your height and weight into the calculator and find your bmi. If your bmi is more than 25, then you may need to have a thinner body. If it is more than 30, then you do need to reduce your weight. How to do that is a long and controversial conversation.
