Casey was a nutrition coach and personal trainer for 13 years giving standard high-carb advice until discovering low-carb through endurance sports in 2012. After transitioning to keto and then carnivore in 2019, he now eats one meal a day and reports improved energy and mental clarity that allows him to be fully present during his demanding 10-12 hour workdays with clients.

From Nutrition Coach to Keto-Carnivore: Casey's Journey
Prior to becoming keto-carnivore, Casey was a nutrition coach and personal trainer for 13 years. The advice was what was typically given, with lots of vegetables and carbohydrates.
Low-carb Diet through Endurance Sports
He found the low-carb way through endurance sports: "I found a higher fat, lower carb diet through endurance sports. At the time, I was racing road bikes, and there was a coach that did a call with us and talked about how he would have world-class Ironman triathletes, and they would eat 50 or 60 calories an hour on the bike, not eating any carbohydrates.
They would eat cream and butter and things. This was 2012, and I was thinking 'what are you talking about? That sounds insane!'. But, I had to nap every day, my recovery wasn't that great.
I slowly started transitioning over to a ketogenic diet, and noticed my fatigue improved greatly, I didn't need to take a nap every day, my energy was much better-all those things people talk about. Over the years, I turned more and more to an animal-based diet."
Discovering the Keto-Carnivore Diet
His first exposure to the keto-carnivore diet was the famous video of Dr. Shawn Baker being interviewed on the Joe Rogan show. He said he didn't even finish the episode, before thinking it wasn't possible to do this diet. He did start to transition fully in 2019, after reading much more about the keto-carnivore diet.
One Meal a Day and Eating for Energy
Currently, Casey eats one meal a day (OMAD), with coffee in the morning with some salt and butter. If he has lunch, it's usually eggs in the afternoon. His biggest meal is in the evening, and it's generally red meat. He eats to full satiety, once a day, usually. That includes workouts he does and training with his athletic clients as well.
The Primary Motivator: Being Fully Present in Life
Casey says his primary motivation is: "To be present in my day and present with my clients. To understand them and help them as much as possible. I need to start my days at 6AM, and I can't just drag myself into the gym into and office and coast into my day. I need to be up, and counting to 12, relating to my clients, and remembering what we did last week, our program design, what their kids are up to…that's been the primary motivator for me: to be able to show up in my life and be fully present.
And so, when I say that my energy is better, I mean that my energy to understand and relate with people, and comprehend, and not need to stop because I'm hungry or hangry, to have great mental clarity, to put in a 10 or 12 hour day, where I'm seeing people every single hour, and I just don't have a lot of time for food. If I can eat this certain way, and it's improving my mental clarity and all these other things, it's so great! It's a wonderful way to live and be able to help other people. That's been the biggest thing that is an improvement!"
