A woman is overweight so her doctor puts her on a diet.
“I want you to eat regularly for two days, then skip a day, and repeat the procedure for two weeks,” the doctor tells her. “The next time I see you you’ll have lost at least 5kg.”
When the woman returns she’s lost nearly 20kg.
“Wow, that’s amazing!” the doctor says. “So you followed my instructions?”
“Yes,” the woman says. “I’ll tell you though, I thought I was going to drop dead that third day.” “From hunger, you mean?” “No, from skipping.”
