|You are NOT what you eat.|
If we were what we ate, then people who ate lots of hot dogs and pork chops would be solid walls of muscle. People who ate lots of pasta would be stringy and fat-free. People who ate lots of pecan pie would be Zooey Deschanel (sweet, but nutty and flaky).
And people who ate a lot of fat would be fat.
What's that, you say? That last sentence is true? People who eat fat are fat? Well, no, not necessarily. Science shows that eating fat won't make you fat any more than eating money will make you rich.
