There are indeed cases in which metabolism, genetics, medical conditions, hormonal imbalances, income and other factors can affect a person’s weight. However, these factors only truly inhibit a small percentage of peoples’ ability to make change. Such cases make up a small percentage of most obese individuals. Physical, positive change in the form of losing excess weight is wholly possible and attainable for nearly all fat people. I agree that fatness doesn’t necessarily determine one’s health. A fat person who exercises regularly can easily be more healthy than a skinny person who stays inside all day. However, fatness does indicate unhealthiness to an extent, and the fact that obesity plagues modern society is a cause for great and immediate concern.
