| Is this the motivation molecule? |
| Motivation comes and goes. One day you're full of get-up-and-go and everything's easy, and the next it's all about sit-down-and-no because you simply do not have the energy. If only there were some way to stay keen? |
| Well, building on an earlier, small pilot study in humans, a recent investigation of motivation in rats suggests that glutathione (GSH), a common antioxidant found in the brain, could hold the key to increasing motivation levels. |
| Researchers found that higher levels of GSH may be linked to more consistent and better performance on tasks that required effort in both humans and rats. Rats fed a substance that boosted their GSH levels improved their performance even more. |
| Researchers are still figuring out all the factors that influence motivation, but according to the new study's author, Professor Carmen Sandi, "nutrition [...] is a good way to improve the fitness of brain circuits regulating persistence in our motivated behavior." |
| It's important to note that the study didn't look at the effects of eating individual foods. But if you're looking to add more glutathione-rich foods to your diet, you might try: |

| There are many reasons motivation ebbs and flows — age, occupation, and sleep quality, to name a few — and many ways to fix that, but maybe, just maybe this antioxidant can help support your motivation at a molecular level. |

| Athletes thrive on low carb diets too |
| Not so fast with the pasta, folks! A recent study shows that carb-loading — wolfing down carb-rich foods before exercise — might not be necessary for reaching peak performance after all. |
| The researchers compared high carb/low fat and low carb/high fat diets in a small group of middle-aged recreational athletes. It took around a month of eating low carb for the benefits to kick in, but after that, they found no significant differences in the two groups' 1-mile race times or sprinting performance. |
| However, there was a twist: Participants who stuck to a high carb diet had larger blood sugar swings, and some even showed levels consistent with prediabetes. Yikes! |
| But don't panic! This was a very small study of only 10 people, with pretty extreme differences between the high and low carb diets. Carb-loading isn't necessarily going to lead to prediabetes. Plus, more research is needed on the role of carbs in exercise performance and the long-term effects. |
| Here's the takeaway: You probably can still reach peak performance without loading up on carbs. And in the long term, your body might thank you for it. |
| Wondering how to apply this in your life? Some quality low carb foods to eat before a workout include high protein snacks such as egg, yogurt, and peanut butter. Or you can try skipping the snacks to see how a fasted workout works for you. |
