a low carb diet and this has me somewhat concerned ... |

brain and carbs
If the brain needs dietary carbs, then Inuits all die of stupidity,
right? The brain can do aerobic respiration same as any other organ and that means it can burn all of the fuel types. Somewhat true. When not in ketosis, the brain uses glucose as a source of energy. When in ketosis, the brain is able to switch to primarily using ketones for energy but still requires some glucose to function. However, the brain's glucose requirements in ketosis are fairly minimal (20g to 30g per day in ketosis vs. 100g when not in ketosis, iirc). Keep in mind that your body can acquire glucose from a variety of sources: dietary carbs, dietary protein, or from breaking down muscle. So you're not going to suddenly become stupid if you low carb; there's plenty of places to get that glucose from. Ketosis is a starvation response to prevent us from dying. The body switches to primarily fat burning to use the stores it saved up during the times of plenty. It would be weird for us to evolve over millions of years with a mechanism for storing excess calories but then have our bodies break down a lot of muscle tissue to keep our brains working. joe |

With the internet, I never need to actually read a book anymore. I just ask and somebody gives me the answer. So, again, my question is "Who needs a brain?" Don't worry about it at all.

Don't worry, your brain is so small it doesn't require energy. HTH

You don't need to be worried. Other foods can also give energy to your
brain. Let's not exagerate your concern. Conny http//sweetpaprika.lipblogs.com |
