Mike Does MHS: Mental Illness as a Metabolic Disorder

What if we think about mental illness as a metabolic disorder of the brain? Harvard Psychiatrist, Dr. Chris Palmer and Michael Giardina of CrossFit Health sit down to discuss this theory, which fills in gaps in what we understand about mental health, draws new connections across the scientific literature, and lays the groundwork for new treatments that use diet and exercise to change brain metabolism.

More Fitter, Less Deader: How Multi-domain Exercise Improves Longevity and Cognitive Function

1

Exercise is broadly known to support health and longevity, but the specific mechanisms by which exercise helps us live longer are not widely understood. Dr. Tommy Wood will review the specific capacities of aerobic fitness and strength — and their combination — to improve health and longevity and reduce the risk of specific maladies such as neurodegeneration. Dr. Wood will provide practitioners with a more informed understanding of how to apply exercise most effectively to improve specific and general health outcomes in patients and athletes.

Reframing Nutritional Microbiota Studies To Reflect an Inherent Metabolic Flexibility of the Human Gut: a Narrative Review Focusing on High-Fat Diets

Is our gut metabolically flexible? In this article, Jonathan Sholl, Lucy Mailing, and Thomas Wood challenge the assumptions that only diets high in fiber are beneficial and high-fat diets are detrimental to our gut microbiome. Instead, they argue our microbiome can be metabolically flexible as long as our food choices consist of whole, natural foods.

Obesity and the Microbiome

In "Gut Feelings: The Microbiome and Our Health," Alessio Fasano, M.D., and Susie Flaherty point to a number of environmental factors that influence obesity, including “sleep deprivation, disruption to circadian rhythms, chronic stress, changes in food composition, labor-saving devices, drugs (including antibiotics), and endocrine disruptors” as well as socioeconomic factors. They also add another variable to the mix: the gut microbiome, the ecosystem of microorganisms in and on the human body.

De-stress and Decompress: Managing the Stress Response

4

In part 1 of this two-part series on stress, we discussed the differences between the sympathetic and parasympathetic branches of the nervous system, the importance of finding balance between the two, and how prolonged stress sends the sympathetic response into overdrive, resulting in chronic inflammation and illness. Now we’re going to talk about how to regulate the stress response in real time as well as techniques for long-term stress management to bring the two systems back into balance.

How the Body Responds to Stress

5

A balance between the sympathetic and parasympathetic branches of the nervous systems is required to keep us on an even keel. Unfortunately, the prolonged stress and chronic illness so prevalent in our society keep the scale tipped in favor of the sympathetic response, turning what would in the short or medium term be a beneficial response into a harmful chronic issue.

Health Tip: Using HRV to Guide Training During Pregnancy

2

Heart rate variability (HRV), or the variance in time between the beats of your heart, can provide insight into how your body is responding to the many different stressors in life. This is a valuable tool to help guide women’s training through pregnancy and postpartum. When HRV is low, it opens up a conversation on what other life stressors are going on and indicates a need to reduce training load.
