Skip it!

The doctor puts the overweight blonde on a strict diet.
"I want you to eat regular meals for two days, then
skip a day, and repeat this procedure for a month. The
next time I see you, you'll have lost at least five
pounds."
When the blonde returns, she's lost over twenty pounds.
"Why, that's amazing!" the doctor says. "Did you follow
my instructions?"
"Yes. I'll tell you, though, Doctor, I thought I was
going to drop dead that third day."
"From hunger, you mean?"
"No, from skipping."
