Mr. Smith was terribly overweight, so his doctor put him on a diet.
I want you to eat regularly1 for 2 days, then skip a day, and repeat this procedure2 for 2 weeks. The next time I see you, you'll have lost 5 pounds.
When Mr. Smith returned, he had lost nearly 20 pounds. Why, that's amazing! the doctor said, Did you follow my instructions?
Mr. Smith nodded. I'll tell you though, I thought I was going to drop dead by the end of that 3rd day.
From hunger, you mean?
No, from skipping!
