We really are fat heads!

That's a big brain!

I read in one of my fitness magazines that our brains are two-thirds fat. That sounded like a lot to me so I did some digging. What I found was a whole shitload of interesting things.

  • First, there seems to be a bit of a discrepancy as to how fat our brains are. I found numbers that range from the 2/3’s to 10%. I know personally that my entire head at one time was 18.3% fat. This was back in the day when I was trying to ride my bike super fast (I had a body scan that breaks you down piece by piece to measure stuff; muscle, fat, bone) By my calculations 2/3’s does not amount to 10% or 18.3% for that matter, but I’m as bad at math as I am with spelling. I guess the fatter your body is the fatter your brain is?
  • The thing about fat in the brain is that the nerves are wrapped in fat; this insulates them and allows the impulses to travel quickly. Greases the way so to speak.
  • The strangest thing I found (remember, you shouldn’t believe everything you read on the internet) is that our brains are the consistency of warm butter. I found that odd. I’ve seen plenty of brains on TV and none of them looked like warm butter. Just last night I saw Ted Danson pick up a brain on CSI and it looked hard and rubbery. If it were the consistency of warm butter wouldn’t it have fallen apart? But then it must have been a fake TV brain.
  • I like this fact as it makes sense, I just never thought about it; the harder, or more you think the more energy your brain uses (energy = calories). Your brain uses as much as 1/5th of all the calories you use in a day. The more you use your brain the larger it can grow. Now, I’m sure that’s true but I wouldn’t worry that your brain will grow so large that it’ll bust out of your skull (your skull can grow too).

Back to the magazine, here are a three of the best foods for your brain:

  • Blueberries – these yummy little balls help to improve memory.
  • Almonds – are high in good fat, which aids in decreasing mental decline and ward off the negative impact of stress.
  • Ground Flaxseeds – are abundant in omega-3 fatty acids.

So there you go. Have a Happy Veterans Day and I’ll see you on Monday…

The scale is not your friend

Fat vs Muscle - That's a lot of fat!

Years ago I stopped getting on the scale. Why? Because it’s full of bull and I have no patience for bull. Why do I say that the scale is full of “bull?” Because it tells me things that have very little bearing in reality.

I learned a long time ago that while the scale may tell you that you’re light (and that’s what most of us want to hear), that doesn’t mean you’re fit, strong or healthy. It simply means that you’re light, or starved, or possibly dehydrated on that particular day. Or, maybe you’ve been dieting and you are low in body fat, but can you jog up a flight of stairs without gasping? Got any muscle tone or are you giggly? You might be light but you may not be fit.

In my mind the best judge of fitness is via the way you look and feel, and the best way to judge the addition of girth is through the constraint of your clothing and reflection in the mirror, rather than the vision on the scale.

Here’s my question: Do you want to be light (thin) or do you want to be healthy? I like being healthy  myself. I am not light, I have never been light, I will never be light and I don’t care about being light according to the scales definition. I don’t need to be particularly “light?”  I’m healthy, fit, and look pretty darn swank as well as can put up a hell-of-a good fight when challenged (I mean in a race or fitness challenge not bar brawl…but I’d be okay there too).

If you want to look light, get fit; get regular aerobic exercise and build muscle rather than fat. A large part of the key to fitness is muscle mass, remember that muscle is denser than fat (%18) so it takes up that much less room in your body. Visualize this, one pound of butter is equal in size to one pound of fat. You know what butter looks like; it’s the whole box of butter. Not one stick, all 4 sticks that come in the box total one pound. Now, one pound of muscle is about the size of your fist. Visually much smaller than a box of butter. Plus, muscle burns calories to stay alive so it works with you to burn fat. Fat just sits there looking lumpy until you burn it off.

This difference in fat vs muscle mass is why you can have two 140 lb women, one a size 8 and one a size 12. Not only does the size 8 women look and feel great, most likely she’ll live a healthy, longer life. Plus, she gets to eat more than the size 12 women because she’s full of strong calorie burning muscles rather than lumpy fat. Now isn’t that worth a little sweat a few times a week?

I’ll be back bright and early on Wednesday with some easy muscle-building ideas.
