A man goes to the doctor worried because he's so overweight, his doctor put him on a diet "I want you to eat normally for 2 days, then skip a day, and repeat this procedure for 2 weeks. The next time I see you, you should have lost 2.5kg". When the man returned, he shocked the doctor by having lost 10kg. "That's amazing. You did this just by following my instructions?" The man nodded. "I'll tell you though, I thought I was going to drop dead on the 3rd day." The doctor asked: "From hunger, you mean?" "No, from all that skipping!"
