Blonde diet

A very overweight blonde woman goes to her doctor for help with her eating problem.
She explains she would like a diet that will actually work for her.
"I want you to eat normally for two days, skip a day. This is the routine I want you to follow. Come back to see me again in two weeks. By then you should have lost at least five pounds. Remember, Eat normally for two days and skip the next. Repeat the 3 days for the next two weeks."
The blonde goes home and faithfully follows the routine for two weeks.
The doctor cannot believe his eyes when he sees her again after two weeks, She has lost around 4 stone!!??
"What did you do asks the doctor? That's amazing, Did you follow my instructions?"
The blonde nods. "I'll tell you though, I thought I was going to drop dead that third day."
"From hunger you mean?" Asks the doctor.
"No," replies the blonde, "from skipping."
