How Your Microbiome Affects Exercise Benefits

/in /by

It seems every day, there are several studies on the microbiome and its impact on our health. At this point, they’re preliminary but the picture is emerging that as goes your gut, so goes your health. I’ve picked three new studies to review this week.

As an exercise physiologist who’s done research on this topic, I’ve always recommended exercise as a way to improve control of blood sugar for prediabetics; that’s why this study surprised me. Researchers assigned 39 prediabetic men who had never used medication to either a control group or a high-intensity exercise group for three months. All men in the exercise group had similar improvement in fitness and weight loss. But only 70% of the men demonstrated an improvement in insulin resistance.

The way the responders processed protein and carbohydrates was different from non-responders. The researchers collected stool samples and then transplanted the microbiome of responders and non-responders into a group of mice; the mice responded to exercise in the same way as the man whose microbiome they received. The microbiome somehow responded differently to exercise and modified the expected results.

We don’t know about dietary differences between subjects that might have impacted the outcome because the subjects were told to maintain their current diet, but the results were surprising nevertheless. But I would still give the same recommendation for exercise to all prediabetics. The only difference would be to make sure they tracked blood sugars to see how their blood sugar responded.

Happy Fat Tuesday!

/in /by

Today is Mardi Gras—in case anyone doesn’t know, Fat Tuesday is the literal meaning of the French term. It’s the final celebration before the period of Lent that culminates in Easter Sunday. Many Christians use this time to give up something they enjoy as a sacrifice. The idea is to reflect and focus on our spiritual self; no matter your beliefs, giving up something you enjoy to focus on your inner self is a good idea. This week, I’m going to talk about giving up three typical categories of food and drink: sugar, salt, and alcohol. What benefits could you gain in the 40 or so days of abstinence from these foods? What may be a healthier substitute?

Let’s start with sugar, and by that I mean cake, cookies, donuts, sweet rolls, pies, ice cream, and candy. These are the ultimate in refined carbohydrates. If you were to abstain from these foods for 40 days, several things could happen. First, your insulin levels would probably drop because you wouldn’t have high levels of sugar hitting your bloodstream. If you’re prediabetic, you might see your triglyceride and HbA1c levels decline. If you had a fatty liver, it would most likely begin to clear up.

What could you substitute that would be healthier? Berries, fresh or frozen, any type, and you could even put a tablespoon of whipped cream on them. The antioxidants and phytonutrients would be better than the refined sugar; fruit sugar is processed differently, so it would not affect your blood sugar. Second choice would be citrus, and third would be apples.

If you’re considering giving up something for the next 40 days or so, make sure it’s something you really enjoy and eat regularly. Paula has a friend from Montana whose father, years ago before every food was available year round, gave up watermelon every Lent. It has to be meaningful.
