A man was very overweight, so his doctor put him on a diet.
"I want you to eat as normal for two days and then skip a day and repeat this procedure for two weeks", the doctor told the man.
"The next time I see you in two weeks time you will have lost 2 to 3 kilograms", the doctor concluded.
When the man returned, the doctor was shocked to see that he had lost 20 kilograms.
"Why, that's amazing!" the doctor said, "Did you follow my instructions?"
The man nodded and said, "Though I have to tell you that I thought I was going to drop dead on each of the third days."
"From hunger?" the doctor asked.
"No, from skipping for 24 hours without a break!"
