Macronutrient Evolution

Fuel. What do you need to power you to your best performance, particularly for competition?

I started off thinking the carb loading of endurance events had something to recommend it. After all, if you can run a marathon, why shouldn’t that be good fuels for a few rounds of fighting? After seeing Tim Ferriss post on the Slow Carb Diet, and subsequently publish The Four Hour Body, I started to see that a diet high in carbs probably wasn’t going to be the best thing to make weight.

So then I was more focused on protein and low carb vegetables, like cruciferous vegetables (broccoli, cauliflower etc) and lefty greens, salads and such.

From there I started to hear about gluconeogenesis, from Ben Greenfield’s podcast, and also from the book Keto Clarity by Jimmy Moore. Basically if you eat too much protein, it gets turned into carbohydrate. Back to the same problem.

Now I’m working on a ketogenic diet. Eating about as much fat as possible, and minimising carbohydrate. A smoothie I make involves a can of coconut cream and an avocado. I have a blood glucose monitor, to regularly check the impact of the meals I eat. I’m also looking to get a device to measure breath ketones. A ketogenic diet also helps with intermittent fasting, sometimes inadvertently, because I’m not overly hungry.
