Here's a diet joke?

[Alicia™]

A woman came to her doctor, "I have problems losing weight. What can I do?"

The doctor told her, "Eat more vegetables."

So she did, but a month later, she came back.

"It didn't help. What else should I do?"

The doctor told her, "Try eating white chicken instead of meat."

So she did, but a month later she came back, still with no results.

He said to her, "Instead of eating white chicken, you should probably eat more fish."

So she did, but another month passed by, and she came back for a visit, still with the same weight.

"What have you been eating this past three months?" the doctor asked her.

"Well, the first month I ate a McDonald's Big Mac,
the second month I had a McDonald's McChicken,
and the third month I ate a McDonald's Filet-O-Fish."

pretty lame, i know
