You think the fat don’t know they’re fat? It’s not like alcoholism in that sense. The realization is there. They
know.

They are the ones who buy their clothes in big sizes. They are the ones who pay to buy an extra airplane seat 'cause they don’t fit in one. They are the ones paying higher health insurance premiums. They are the ones who have trouble moving. They just aren’t ready to do something about it, or maybe can’t figure out how to do something about it. Maybe they’ve had a mobility injury and can’t exercise. The disgust with the size just leads to a vicious cycle of eating, disgust, etc.
It is nobody’s business what they put into their mouths to eat, any more than it is anybody else’s business what they drink. But, just like any alocoholic or drug abuser, there are consequences to being fat, some of which are mentioned above.
It’s not the same as a drug or alcohol addiction, though. We all need to eat to live, saints and those on permanent IVs notwithstanding.
In my opinion, an intervention is not a good idea.
If they are dining at your house, you are the host. You choose the food. If it is prepared healthfully, then all you have to do is offer it. If they say, “No thank you” that’s their problem. You do not have to offer high-calorie desserts or anything else you don’t want to offer.
If you are the host in a restaurant, then you still get to choose. You can call in and order beforehand.
What you do not get to do is tell people how to spend their own money if you’re going dutch treat.
