Matrix Cuisine

In the movie, the Matrix, our world is just the computer simulator world called the Matrix. Our physical bodies are hooked up to all kinds of tubes in a slimy, gooey liquid-filled pod. Everything we do, see, hear, and interact with is just stimulations to our brains.

So my question goes like this: There is no real food in the matrix. It's all computer simulated to make our brains think we're getting the nutrition we need to live, because as we all know if you die in the matrix, you die in the real world. In the matrix we think we're eating. In the real world, our bodies are getting the liquid goo-type food from an IV to really keep us alive.

So if a person becomes really fat from eating too much in the matrix, does the physical body that's only getting liquid sustenance also get fat? I know that their brain is thinking they are, but in real life, they aren't actually eating all those fatty foods. So do their physical bodies get fat?

Discuss.
