Expert Interview: Vegan Athlete, Dan King
When Boulder, Colorado-based international champion runner Dan King turned the big โFive-O,โ making the switch to a whole food plant-based diet was a no-brainer for a man whoโs been running competitively since high school but has really hit his stride since going plant-based nine years ago. Kingโs athletic performance has been nothing short of stellar, and heโs seen tremendous improvements in his health.
HEALTH BENEFITS
โI had a physical and bloodwork when I turned 50 just as I was making the dietary transition. My total cholesterol at the time was 180, and my blood pressure was OK but not great. Three months later, I had to get another physical to support an insurance policy. My cholesterol was down by almost 50 points, and my blood pressure went into the โbest category.โ I was pretty surprised by how much my values on all those things changed,โ King said.
At 59, King takes no medication but does take a few supplements โ vitamin B12 and vegan omega 3โs derived from algae, and vitamin D3 in the winter.
โIโve had some great success, all as a 50-plus-year-old athlete,โ King told Plantbasedcooking.com.
ATHLETIC SUCCESS
While King has, as he puts it, โpodiumedโ (i.e., won first, second, or third place medals) consistently in age-group (โAGโ) races nationally and internationally since he turned plant-based, heโs perhaps best known for his stint as the โWorldโs Fittest CEO.โ King clinched the CEO Endurance Championships in September 2012 in Tennessee. Twenty CEOs at the top of their fitness game, many significantly younger than King, competed in a three-day, six-event competition consisting of running, cycling, swimming, and an obstacle course.
More recently, King won first place at the 2015 USA Track and Field (USATF) Cross Country Championships in Boulder, Colorado, and the USATF Club Cross Country National Championships in San Francisco.
Also in 2015, King won the 5,000-meter bronze medal at the highly-competitive World Masters Athletics Track and Field Championships in Lyon, France.
That half-century, 50-year mark was an especially significant milestone for King, a โsemi-retiredโ telecommunications executive, entrepreneur, and self-described former ski bum whoโs currently working toward a possible career in nutrition. King is the brother of champion runner Laura Bruess, recently profiled in an article on Plantbasedcooking.com along with her husband, runner, and coach Rick Bruess.
WHY PLANT-BASED?
โWhen you turn 50,โ King said, โthatโs when you need your first colonoscopy. Itโs also when you start to see health changes in the people around you. Getting your first colonoscopy can lead to a kind of recalibration, and I took it as an opportunity to reflect. I decided I wanted to live into my senior years and be able to do the physical things Iโve done my whole life โ downhill ski, ride my bike and run. So that was absolutely part of my consideration.โ
โI also wanted to continue to be a competitive athlete, so I want to eat in a way that enhances my ability to compete,โ he said.
King described the athletic training process as one of stress and recovery, noting that many athletes donโt fully appreciate the importance of recovery.
โIf recovery isnโt good, you wonโt get the performance you want from the hard training that you do,โ King said. โIf youโre not paying attention to recovery, youโre missing the forest for the trees, itโs equally important to the high physical stress.โ
โPlant-based diets tend to be much more anti-inflammatory at a cellular level, where all these physiological adaptations are happening. Youโre doing micro levels of damage when you train hard. What you put in your body every day has a huge influence on how this goes over time,โ King said. โSleep, yoga and mental stress relaxation, mindfulness, things like that are also important when youโre competing at a high level.โ
For some people, overall health and athletic advantage might be enough to justify a plant-based diet. But King is a man with a strong social conscience, and that led to his third reason for going plant-based.
โFor me, itโs important to make decisions around food that conform to my values, Iโm one of those people that would consider myself environmentally minded. I find that the way our society condones animal agriculture in factory farms repugnant from an ethics standpoint and potentially harmful as it relates to health, not to mention ecologically unsustainable,โ King said.
โI also read the book โThe China Studyโ by T. Colin Campbell, which had a huge influence on how I was thinking about food and health at the time,โ King said. (โThe China Studyโ examines the link between consumption of animal products and the incidence of chronic diseases.)
King was pleased to report that he recently earned a Plant-Based Nutrition Certificate from the T. Colin Campbell Center for Nutrition Studies. The certificate program is offered online through Cornell University. This fall King will continue his studies with nutrition coursework at the University of Colorado.
VEGAN vs. PLANT-BASED
King distinguishes between โveganโ and โwhole food plant-based.โ
โFor me, vegan connotes as much as what you donโt eat as what you do eat. You can be vegan and not be healthy. I think โwhole food plant-basedโ better describes what I try to eat rather than what I avoid. I eat lots of fruits and vegetables, legumes, whole grains, and some nuts. You can eat a lot of sugary, salty, and oily processed foods as a vegan that arenโt particularly healthy or performance promoting,โ King said.
โI often get asked by friends where I get my protein. Itโs hard to get away from the protein-focused mindset as an athlete. Iโm confident that I get sufficient protein from my regular plant-based diet, but Iโll occasionally supplement with a plant-based protein shake just for peace of mind when Iโm training especially hard. My diet probably works out to be about 75-80 percent carbs, 10-12 percent protein, and 10-12 percent fats,โ King said.
King said he cooks more than he used to because it gives him more control over what he eats.
โI go out of my way to avoid added sugars. I donโt avoid but minimize added oils to foods and try to leave out GMO crops altogether. I have super concerns about those. I eat organic, and supposedly there arenโt GMOs there,โ King said.
OTHER INFLUENCES
In addition to T. Colin Campbell, King takes inspiration from Dr. Michael Greger and Michael Pollan, food journalist and author of five New York Times bestselling books, including โThe Omnivoreโs Dilemma.โ
โIโm very evidence-based in how I think, and thatโs Gregerโs approach; what does the science tell us? I say that knowing that a lot of the science that you come across in nutrition is inherently biased for a number of reasons, and you have to be super careful when trying to suss it out โ yโknow, who funds these studies?โ King said.
King swears by a podcast by Rich Roll, a plant-based endurance athlete in his early 50s.
โRoll interviews, super-interesting plant-based people, like cardiologist Joel Kahn and Dr. John McDougall, Dr. Caldwell Esselstyn and his son Rip Esselstyn, and also Dr. Neal Barnard, heโs very compelling,โ King said.
KINGโS PLANT-BASED FAVES
Breakfast
โMost days I just eat plain old-fashioned rolled oats with a bunch of nuts and dried or frozen fruit and almond milk,โ King said.
Lunch
โOne of my favorite go-to lunches are big bowls with quinoa or brown rice and some kind of legume, like black or pinto beans or lentils. Then I throw in a bunch of avocado and salsa on it. I love Latin foods. Itโs quick and easy and a high-health equation lunch,โ King said.
Dinner
โI basically eat what I always used to eat, such as stir-fry veggies with โchickenโ and brown rice, fishless โfishโ sticks with mashed potatoes, and, of course, big salads on the side. Those mock meats are so good now compared to 10 or 20 years ago, you donโt need to make sacrifices if you want to be plant-based,โ King said.
Desserts, Smoothies, and More
King often bakes, including making sugar-free banana bread each week. His favorite โgooey tastingโ brownies are made with almond butter, dates, cocoa powder, and chocolate chips, and he also loves these fig newtons made with almond and coconut flour.
King makes his own cashew cream at home with cashews and a little bit of water in a blender as a substitute for half-and-half.
โWith these innovations, you can satisfy the brain cravings of things you grew up loving โ you can still eat what you like!โ he said. โThere are so many ways to hack the traditional things we used to cook with.โ
King thinks itโs important to leave the fiber in food. He makes smoothies in his Vitamix blender instead of juicing.

WHATโS NEXT
โIโm turning 60 next year. I thought would be fun to try to run a 5-minute mile after age 60, so thatโs kind of a high bar,โ King said. Danโs Sugar-Free Banana Bread
