Happy Tuesday, everyone!
I’m going to be talking about 3⃣ things in this newsletter: a never-before-offered program that starts NEXT week (!!!); my brother’s earth-shattering episode with Joe Rogan, which aired last Friday and is sending shockwaves through the political world; and a new document released by the Kogi people of Colombia outlining their views on the future of AI, which I think everyone should read. Let’s jump in! 👇
🔄💪 I need a reset! Do you?

Our baby just turned one (yay!!), which is one of the most exciting milestones I’ve ever experienced. For two years straight, I’ve been pregnant, giving birth and recovering, or breastfeeding around the clock. Nurturing our little guy has been, by far, the best experience of my life, but it has also been tough on my body. Now that he’s one, I’m starting to wean, and my husband and I want to try for another baby sometime in 2027. That gives me a precious little window to rebuild my strength, get in the best shape I can, and maximize my energy and mindset before the next big chapter. I’m excited! Let’s go! 💪
I’m starting off this rebuild period by spending the next six weeks following the principles of my own book, Good Energy, and putting it ALL into action. There’s no reason to wait for the new year, and I don’t have time to waste! 😄
Maybe you don’t either? Maybe you’re coming out of your own season of depletion, whether that’s a new baby, a hard year, or a stretch of time when the habits that make you feel like yourself slipped away? Maybe it’s nearing the end of the year and you haven’t adopted the healthy habits you intended to? Instead of waiting for January and trying to dig out from the holidays, what if you walked into the new year already feeling stronger? Because health is always done better in community, I’m inviting you to join me. ❤️
For the first time ever, I’m opening up a six-week group program, the Good Energy Reset, and I’m SO excited about it.
I’m simplifying the plan from my book into just 3 simple daily commitments to get us through the holiday season thriving: eat for Good Energy (five things IN every day, three things OUT), move for 30 minutes, and practice five minutes of stillness. That’s it. We’re not trying to overhaul our lives overnight. We’re practicing a few foundational habits consistently, right through the holidays, together. The goal is to finish this year strong and proud of ourselves.
Here’s what we’ll do together:
💬 10 LIVE, 60-minute teaching workshops with me on Zoom, every Tuesday and Thursday evening. This is the heart of the Reset: real time together, where I’ll teach some science and practical tips behind the Good Energy principles, answer your questions live, and help us set practical intentions between sessions. Every workshop is recorded, so you can catch up if you can’t make it live.
💡 Practical resources to make it easier, including my Good Energy AI Companion to support your food goals, the Complete Good Energy Food List, a Holiday Eating Guide for parties and travel, and a Six-Week Daily Tracker for your commitments.
I’ve NEVER offered live teaching before to this community, and I’m thrilled at the chance to connect with you in real time. Space is VERY LIMITED to keep the group intimate, so if you think you’d like to join, I encourage you to sign up now.
If live sessions aren’t right for you right now, you can follow along with my personal health journey through what I’m calling “The Inside Track.” Every week, I’ll send a video and email update with my actual glucose and ketone data, my food journals, my body composition, sleep, movement and recovery progress, and honest reflections on what’s working, what’s not, and what I’m learning. Follow the journey here.
Let’s have fun and end the year strong together!
🎙 My brother on Joe Rogan 🔥
My brother went on Joe Rogan last week, and it was explosive. If you didn’t know, my brother, the co-author of my book Good Energy, was asked to work in the administration to help bring many of the principles from our book to life at the national level. He’s been leading food policy between the White House and Health and Human Services for almost two years, tirelessly pushing for updated dietary guidelines, healthier food in all public schools, better military food, getting soda taken off federally funded food programs like SNAP in several states, and many other wins. It has been a Herculean effort, with unbelievable amounts of internal politics and the relentless heavy hand of special interests trying to push down his efforts at every step.
He resigned two weeks ago after facing unfathomable stalling on his effort to release the government’s definition of ultra-processed food, which is a simple first step toward changing the rules about what can be served in federally funded meal programs like school lunches.
His episode with Rogan unpacking what he experienced in the last 2 years reached millions of people in just three days. There have been major shakeups in senior White House leadership since it aired, and two days later he appeared on Face the Nation on CBS. You can watch the full episode here. I’m SO proud of my brother and the courage he has to speak the truth – can you imagine if more people had the strength of character to do this?
🚨 An urgent message from the Kogi on AI
The third thing I want to share is an incredible document released by the Kogi (Kogui) people of Colombia about their perspective on AI, entitled “AN URGENT MESSAGE ON ARTIFICIAL INTELLIGENCE FROM THE KOGUI PEOPLE.” If you’ve followed me for a long time, you know I’ve mentioned the Kogi many, many times:
I can’t fully explain it, but I feel a deep connection to the Kogi people. Three and a half years ago, I had never heard of them. Since then, their message has come to me through about five different sources, all out of the blue: their documentaries, people I happened to meet who had been to their village, spiritual teachers connected to them, and a book of their teachings I stumbled upon. It has been fascinating to watch their message keep finding its way to me. The Kogi call themselves the Elder Brothers, and for decades they have been warning us, their Younger Brothers, that the Great Mother is suffering and that caring for her must come before everything else. I believe their words are profound, that the future of life depends on heeding them, and that sharing this message is part of my mission.
The link below takes you to a PDF of the English translation of this work. I’ve been in touch with a spiritual leader who is in contact with the Kogi to verify that these are indeed their words. I urge you to read it as we think about the impact of technology on the future of all life on planet Earth.
So we say to you: artificial intelligence cannot be separated from the thought that is making it.
If that thought is born from concern for life, this technology can help protect life.
If it is born from ambition, from competition, from accumulation, from the desire to dominate, it will express and amplify those things.
Artificial intelligence is a mirror.
But a mirror that only reflects would be harmless.
This mirror has the potential to greatly magnify all that it reflects.
The danger is an unconscious people holding great power.
You can read more of my thoughts on this document in last week’s Poem of the Month, which I’m opening up for free this week. If you want more writing like that, sign up to become a Good Energy Steward.
With good energy,
Casey
