Mastering Nutrition

Hi, I'm Chris Masterjohn and I have a PhD in Nutritional Sciences. I am an entrepreneur in all things fitness, health, and nutrition. In this show I combine my scientific expertise with my out-of-the-box thinking to translate complex science into new, practical ideas that you can use to help yourself on your journey to vibrant health. This show will allow you to master the science of nutrition and apply it to your own life like a pro.

Our consciousness is like a net. We want the net to be fluid enough to let thoughts that bother us pass through without grabbing our attention, but strong enough to grab on to the ideas and motivations that will drive us to achieve what we value in life. Nutrition has a big impact on this net. In this episode, learn how foods like liver, egg yolks, meat, leafy greens, legumes, collagen, bone broth, spinach, wheat, and beets can impact how fluid or stable your mind is by impacting the methylation of dopamine, and how to achieve the proper balance.

This episode is brought to you by Ample Meal. Ample is a meal-in-a-bottle that takes a total of two minutes to prepare, consume, and clean up. It provides a balance of fat, protein, and carbohydrate, plus all the vitamins and minerals you need in a single meal, all from a blend of natural ingredients. The protein is from whey and collagen. The fat is from coconut oil and macadamia nut oil. The carbohydrates, vitamins, and minerals come exclusively from food sources like sweet potatoes, bananas, cocoa powder, wheat and barley grass, and chlorella. I use Ample on Mondays when I have 12 hours of appointments with breaks no longer than 15 minutes. It keeps my brain going while I power through the long day, never letting food prep make me late for an appointment.

This episode is brought to you by US Wellness Meats. I use their liverwurst as a convenient way to make a sustainable habit of eating a diversity of organ meats. They also have a milder braunschweiger and an even milder head cheese that gives you similar benefits, as well as a wide array of other meat products, all from animals raised on pasture.
