SILVER SPRING, MD—Greg Geisinger, a 265-pound Wilmington man whose seven-year marriage ended in divorce earlier this month, must get back down to his dating weight of 190 pounds, he announced Monday. "Oh, man, I have got to lose this weight if I'm gonna be back out there dating again," said Geisinger, who for years has carried 75 pounds of excess marital flab on his 5'11" frame. "No good-looking single woman is gonna want to go out with a guy who looks like this." Geisinger said he is eager to remarry so he can gain back the weight he is about to lose.
