I don’t place much value on conventional wisdom.
This blog has served me through the years as a place to sort out my thoughts, express my feelings, absorb my rage, share my positions, and relate my experiences. I initially created it to write about endurance training, then it wandered into life on the farm, then religion, politics, the intersection of religion and politics, and now this entry circles back to endurance training.
I’ma do it again.
For those readers who haven’t followed this blog, I completed an Iron-distance race in 2010, the year I turned 50. It was wonderful and gratifying and difficult, and now I want to do it again.
Training for an ultra-distance race requires a progressive, linear plan that includes nutrition, running, swimming, cycling, recovery, research, and race planning, among other things. It’s my plan to compete in an Iron-distance race in either 2020 or 2021, which means my path to completion begins now.
Back to my opening sentence.
Conventional thinking holds that training for a race such as this is best promoted by the standard nutritional dogma of high carbohydrate, moderate protein, and low fat. Science teaches us that the human body can burn different types of fuel, glucose/fructose or fat. The Standard American Diet (SAD) is one in which carbohydrates are abundant, ubiquitous, and inexpensive. Looking at high-performance through that lens, it’s reasonable to deduct that, since we do burn glucose, and a lot of fuel is required for endurance performance, one should consume volumes of this macronutrient in the form of carbohydrates, up to and including during the endurance event itself.
Here are 3 of the first-page Google results to “nutrition for ironman training”.
Load 1/3 your plate with complex carbs.Energy is essential for an endurance athlete, and nutrient-dense carbohydrates—like potatoes, rice, and whole-grain pastas and cereals—replenish glycogen and stimulate insulin production.
Your body also needs a lot of carbohydrates to support training and recovery. Your carb needs can easily increase from 5 grams per kilogram per day to 8-plus grams when training jumps from an hour to two or more hours a day (a jump from 350 to 580 grams of carbs per day for a 160-pound athlete, and from 275 to 430 grams of carbs per day for a 120-pound athlete).
Most of the calories in your diet should come from carbs — 55 to 60 percent. That’s because carbs are your body’s preferred source of energy, especially when working out for a long period of time. Getting enough carbs also spares protein, so you don’t burn muscle when training. For proper fueling, most of your carbs should come from complex sources, such as whole-grain bread and cereals, beans, pasta and potatoes.
I’m not terribly keen on conventional wisdom. It lulled me into accepting religious dogma for years. It betrayed me as a young adult into believing debt was a “financial tool”, which would serve me well as I matured. And nutritionally, IMO, it has kept millions of Americans (including me at one point) unhealthy, overweight, and unhappy.
So I’m not relying on conventional wisdom this time. I’m using my own research. I’m using my own data. And I’m using my own body.
I will write about that which I am an expert: Me.
This biohacking, experimental, n=1 journey upon which I’m embarking will be based on loads of personal data: blood glucose and ketone testing, sleep patterns, fasting schedule, stress management, weight, training stats, mood, activity, workouts, nutrition choices, bio-feedback, and sensations.
At the present moment, I’m describing myself as a fat-fueled, high-fat, low-carb, moderate-to-high protein, intermittent-fasting human being. I seek to be in ketosis most of the time, which simply means being in a fat-burning mode rather than a sugar-burning mode. I’ll use the shorthand “keto” often to describe this state.
I won’t insult the scientists, researchers, and doctors by trying to lay out all the science-y stuff myself; I’ll post several resources that I have used to reach my current conclusions about nutrition (critical word “current” – science is ongoing, as is my learning). Nutrition science is not my field, it’s not my formal education, and at best I could only give a layperson’s interpretation of the incredibly complicated process of nutrition.
It’s my intent to have this blog be the journal of the journey. I commit to both honesty and transparency in relating my progress. My general plan is to compete in a Sprint triathlon or two and an intermediate triathlon this summer (2019), continue training through the winter, then compete in a Half-Iron, then a Full Iron in 2020, with wiggle room to delay til 2021 if beset by injury or illness or life circumstances. This will be in addition to various road- and cycle- races that catch my fancy and fit my schedule.
Buckle ups, buttercups. Here we go.
Thanks for reading.
Suggested resources – These are just a few of my favorites. There are scads of resources currently for the keto lifestyle. I’ll add specific topic links as I write about them.
