A woman was terribly overweight, so her Doctor put her on a diet.

Doctor says, "I want you to eat regularly for 2 days, then skip a day, and repeat this procedure for 2 weeks.

The next time I see you, I bet you will 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 yes, "I'll tell you though, I thought I was going to drop dead that third day."

The Doctor looking somewhat puzzled says: "From hunger you mean?"

"No, from skipping."
