Some various thoughts that flow from one to the next:
- A PhD candidate in ecology once told me that he didn’t understand how people gained weight from calories. “Isn’t it just energy?” It was a rather startling reminder of just how stratified different fields of science are. I explained that extra energy is stored as fat in the body.
- I was listening to a Star Talk Radio episode during my run yesterday and they talked about how you have to have an energy source to make a starship start flying (that is, to overcome the pull of gravity). So I started trying to work out the science of exercise in my head.
- I’ve been slowly trying to understand eating for fitness. It’s pretty sad that I’m most comfortable with eating for weight loss, not for supporting physical fitness (though there are definite huge overlaps, since I don’t believe in unsustainable diets).
- I had one of those, “Oh wow, evolution is beautiful” moments this morning. Here’s what hit me: Our body is designed to quickly and easily provide that energy we need to overcome inertia/gravity/etc whenever we decide to move. We barely have to think about doing it. This is incredibly basic science, but it was never explained that way in high school. No one ever took our Biology class and our Physics class and said, “Here is a real-life, everyday example that matters for you: do you realize HOW CRAZY IT IS that you can just start walking right now if you want to?” (I could rant for hours about how little of our high school curriculum was made applicable to everyday life, and therefore accessible/relevant enough to really engage us in the subject matter.)
- I did a quick Google search and found this website that basically breaks down the whole calories become energy and fat thing and very briefly touches on the Physics of it (the potential energy/kinetic energy that our body uses).
- I wonder what the reaction would be if, like in the website above, schools actually taught students how to calculate their calorie needs based on their activity levels. I think it would be tremendously useful and could be done in a healthy way. There is so much misinformation out there, and high school is the perfect age to address it (here’s a really fabulous article about it). We have the information, but it’s getting buried under layers and layers of misinformation and media agendas. And if this isn’t “Biology” and “Physics” and “Chemistry,” then something is wrong with our curriculum.
