>>76564You can obviously date a girl and help her lose weight, but there's 2 main problems with this
1: You have to actually get her to stop being such a fat fuck in the first place. It's likely she just won't.
2: You're increasing her LE SEXUAL VALUE, therefore the reasons that she chose to go out with you in the first place aren't the same. If she starts getting attention from more attractive men, there's no guarantee she's going to stay with you.
If the OP is implying that you don't date her until she's a "SISA", then she has even less reason to start losing weight in the first place (many people will just find it rude if you start pestering them about their weight,) and even less reason to stay with you afterwards.
