Never? I have known some obese females who married and stayed married. They work. Their husbands work. I am not so sure about obese males staying in happy, long term relationships.
The other day, hubby and I met several members of a large family. Pun intended! They were some of the nicest, happiest, most welcoming people we have met in a while. The matriarch was stick thin at 83. Lol. But her children have had a lifetime of really good eatin.
