I'm not sure how much I've talked about this (come on google, search within a collection should be easy), but I have a family history of major problems as a result of complications from the fatness.

I've been trying -- and failing! -- to lose weight for years.

I'm scared of diabetes. Of strokes. Of heart disease. But, that's all far away and hasn't worked as sufficient motivator to lose weight.

I also think that if I continued to be fat and to gain weight each year when I could have done otherwise, that that'd be a morally blameworthy action.

Let me explain that a little, as I lose people there.
Guiding Principle: If I know the outcome of a situation, and do not act to prevent it, I bear (some measure of) responsibility for the outcome.

Belief 1: I and pretty much I alone am responsible for what I put in my mouth. I control my limbs, and control how much I exercise.

Belief 2: I know that being fat will (or, rather, is likely to, but it works the same) result in major medical problems in twenty years, for me. Note: This has little if anything to do with your weight, and has to do with my family medical history.

Lemma 1: I am responsible for the medical outcomes that happen if I am fat.

Belief 3: Medical resources are not infinite; if I go to the ER for a heart attack, then someone else has to wait for treatment or go without.

Lemma 2: If I suffer from preventable medical treatments, other people will be harmed.

Along with the guiding principle, we get something like:
Conclusion: My being fat is a contributory & morally blameworthy factor that causes harm to others.

So ... yeah. I want to lose weight. More than that, I think it is morally blameworthy for me not to. I think my being fat would cause harm to others, and that I can prevent that harm by not being anymore.

I've intentionally put this into the language of logic, more or less. I've tried to make it less emotional, because damn my feelings on this remain raw. It gets into all sorts of issues, but I think this is fairly clear.

I've tried to stress this throughout, and will do so again here: This is about me. Its not about you. I'm not calling you immoral. I'm not saying what you should or should not do.
