That falls under the saying "No spice like hunger." It's just kind of an extreme situation for it.

I can relate, actually.

I had a terrible first pregnancy and threw up constantly for most of it. Once the baby was born, my husband rushed off to Burger King to get me a burger and fries and I wolfed it down. It was half gone before I realized what was "weird": I had been picking at my food for months.

I don't even usually eat burgers, but was also all "Wow, soooo good!"
