Many people who embark on diet and fitness plans have not yet acquired the tools to oversee their plan's effectiveness. Lack of self-control, moderation or diligent application to an exercise program is precisely the way they gained those extra pounds to begin with. So is it fair to expect the overweight loved one to cultivate self-discipline on a whim?
When saying I love you anyway isn't enough
Everything from the latest fashion to the size of airplane seats sends a message to those who suffer from weight problems that they are expected to adhere to a certain socially-acceptable body size. Knowing that they have the unconditional love of the person at home isn't enough when the rest of the world eyes them with revulsion -- or looks away entirely.
A person who is overweight may be passed over for a job opportunity because of their physical appearance. Or they might find themselves wandering in the plus-sized department only to find that they are limited to a bland, limited selection of clothing. These cues tacitly tell a person suffering from weight problems that they need to shape up or risk being excluded.
