A woman was terribly overweight, so her doctor put her on a diet. "I want you to eat regularly for two days, then skip a day, and repeat this procedure for two weeks. The next time I see you, you'll have lost at least 5 pounds."
When the woman returned, she shocked the doctor by losing nearly 20 pounds.
"Why, that's amazing!" the doctor said. "Did you follow my instructions?"
The woman nodded. "I'll tell you though, I thought I was going to drop dead that third day."
"From hunger, you mean?" "No, from skipping."
