Obesity can exist for lots of reasons (I'm not a medical professional), but think about loosing weight like this:
Imagine if you were an alcoholic or crack addict or gambling addict trying to quit. However, you still had to have just ONE drink a day or ONE hit a day or 10 minutes at the slot machine a day to survive? Think about how hard that would be? Fat people can't just quit cold turkey. In order to survive they have to continue to take in the very substance that they are trying to quit being addicted to..
Loosing weight is very difficult..... But not impossible.. I am 5'9. 6 years ago I was 340 lbs.. Today I am the same height and weigh 190.. I did it with diet and exercise, diet mostly, but it wasn't easy... Would have been a lot easier if I could have quit food 100% cold turkey, but that ain't feasably possible.
As for dating fat chicks, I've had guys tell me that fat chicks aren't as much stress, headache, and games as "slimmer" chicks.. They have also told me that they take better care of ya in a LTR and are less likely to cheat or leave ya.. I believe all of that, it makes complete common sense..
However, I also believe that some guys just can't get attracted to chicks past a certain "fattage", even if they want to. That includes myself. Each guy is different.. For me, I can be sexually attracted chicks that weigh about 50 lbs more than I do, same height. But any more than that, and it ain't happenin.. The crane is out of operation, no matter how much I would love for it to be up and building big things.. lol I think that's just something that's programmed in us guys brains', and there's nothing we can do about it..
