Masterclass With Masterjohn Energy Metabolism is a structured course that begins with foundational principles and progresses to advanced topics to give you everything you need to know about the biochemistry of how we break down food for energy, use the energy, and store the excess. It broadcasts FREE on YouTube and Facebook twice a week and is now in its 31st lesson. As a subscriber to the Mastering Nutrition podcast, you will now get the cliff notes of these lessons in audio format.  This gives you three ways to engage with the course: If you just want the cliff notes, sit back and relax. As long as you're subscribed to the Mastering Nutrition podcast, they'll pop up in your feed one by one, every day that there's no other content released in the feed. That begins with lesson one later today. If you want to watch the full lessons, you can do so using the YouTube playlist, by going to the videos section of my Facebook page and playing the playlist, or by going to chrismasterjohnphd.com, hovering over "Masterclass" in the main menu on desktop and clicking the dropdown arrow to the right of "Masterclass" on mobile, and choosing "The Free Version." Sign up for MWM Pro for early access to content, enhanced keyword searching, self-pacing tools, downloadable audio and transcripts, a rich array of hyperlinked further reading suggestions, and a community with a forum for each lesson. However you choose to engage, enjoy!
