Dating someone with the goal of them losing weight is a terrible idea. It often takes serious consequences for such people to follow through with their words.

If you date an overweight or obese person, it's highly likely that they will stay that way forever. Sure, they will tell you that they have been trying to lose weight and want to lose weight etc. They may even workout with you and so on. However, they likely won't pursue that goal seriously until they get their feelings hurt and wake up to reality. Often times, what fixes such people is their partner leaving them because of their weight, unfortunately.

If you have kids with such a partner, you have to work extra hard so they don't make your kids obese as well by instilling in them unhealthy habits. It is just not worth the trouble.

Some people won't date obese people not for lack of attraction, but for the deeper issues and the consequences that follow, as listed previously. It's more than "hey, this person looks fat." It's the personality and lifestyle that comes with it. Their lack of accountability is beyond infuriating.
