A blonde woman went to her doctor after realizing she had put on a few extra pounds. She wanted to lose weight quickly before an upcoming event, so the doctor gave her a simple plan.

“I want you to eat normally for two days,” the doctor explained, “then skip a day. Repeat this for two weeks. If you stick to it, you’ll lose at least five pounds by the time I see you again.”

The woman wrote everything down carefully, nodded, and promised to follow the instructions exactly.

Two weeks later, she came back looking exhausted — but also noticeably slimmer. The doctor was impressed.
“My goodness!” he said. “You’ve lost nearly fifteen pounds! Did you really follow my instructions?”

She nodded. “Yes, exactly as you said — two days eating normally, then one day of skipping.”

The doctor smiled. “Wow, I didn’t think it would work that well! But you look exhausted. Were the ‘skip’ days really that hard?”

The woman sighed. “Hard? You have no idea! I almost didn’t make it through the second week.”

The doctor frowned, confused. “Wait… what do you mean?”

She replied, catching her breath:
“Well, I ate for two days like you said, then on the third day, I started skipping — all day long! Around the house, down the street, even in the park! My legs are killing me!” 

The doctor nearly fell off his chair laughing.
