I learned something new today over at Diet Blog. Our big, human brains require about twice as many calories as the brains of other mammals. No wonder we overeat, right?

You know, it makes sense if you think about it. When our ancestors were spending their days hunting for food and running to avoid being food, they needed a lot of food to sustain themselves. Their brains cued them to eat lots of calorie-dense in order to keep their large, growing brains satisfied.

And our big brains are still cuing us to eat calorie-dense foods, but the problem is that now, calorie-dense foods are often laden with saturated fats and they're super easy to get. Pair that with the fact that many of us have sedentary jobs and busy lives that don't leave time for daily workouts, and ... well, I'm blaming any extra pounds on the fact that my brain is just so darn big. I like that excuse far better than my lack of willpower.
