I might be crucified for this: but, unless you have a medical condition / something that impacts your metabolism, or ability to process food - obese people strike me as weak-willed (to put it nicely). It doesn't take THAT much effort to shop for and eat healthy (ier) foods, or to do SOME type of physical activity a few times a week. You can walk three miles in an hour. Everyone can do that after work before dinner, or after dinner before needing to put kids to bed.
