What do the wind and women have in common?  Once they get too heavy, no one really likes them.
Are you joking about people who are overweight? I don't think that's very nice.
No it's not a joke, really. They should get that fat off and go work out
There are a lot of reasons that people gain weight, and it's very hard to lose weight and keep it off. Suggesting that no one likes fat women is pretty mean, and could make a lot of people around you feel awful. I would instead suggest kindness and compassion for everyone.
