A blonde woman is terribly overweight, so her doctor puts 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 five pounds."

When the blonde returned, she shocked the doctor by losing nearly 20 pounds.

"Why, that’s amazing!" the doctor said. "Did you follow my instructions?"

The blonde nodded. "I’ll tell you though, I thought I was going to drop dead that third day."

"From hunger, you mean?" asked the doctor.

"No, from skipping."
