"A blonde was terribly overweight,..." joke

A blonde was terribly overweight, so her doctor put her on a diet. "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, you'll have lost at least 5 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 3rd day."
"From hunger, you mean?"
"No, from skipping.
