A fellow was terribly overweight, so his doctor put him 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 should have lost a least 5 pounds".
When the man returned, he shocked the doctor by having lost nearly 60 pounds!
"Why, that's amazing!" the doctor said, "Did you follow my instructions?"
The man nodded... "Yea, but I'll tell ya, I thought I was going to drop dead by the 3rd day."
"From hunger, you mean?"
"No, from skipping all day."
