1/27/13 - Nutrition Experiment: Carb Backloading (2 of 3)

Last week I introduced my experiment with a nutritional strategy called Carb Backloading. Chances are it was the gross amounts of pizza and ice cream that perked your interest about CBL. Well, in Part 2 of this series I’ll get into the ‘Dirty’ version of my experiment. The third and final installment will cover the ‘Clean’ version of my two-part experiment.

The ‘Dirty’ version of this CBL experiment more specifically describes the types of foods that I relied on for my carb backload feedings. This version included a pretty “anything goes” type of structure. All week long I remained ketogenic, or relied on just 30 or so grams of carbohydrates per day, while feasting on protein and fat for fuel. It’s worth noting that I never was hungry, nor do I condone any strategy that supports such a thing.

It was after heavy training days of usually at least a long strength session and a tough metabolic conditioning effort that I’d back load (3-4 times per week). The back loading session consisted of crushing 300-400 grams of carbohydrates near the end of the day. To give you an idea of what that looks like consider that a large Pizza Hut pepperoni pizza has 272 grams of carbohydrates.

You can imagine that it’s quite a feat to consume that type of volume. It was fun to try, however. On the first CBL night I had Lindsey and I’s regular dinner that included a bison top sirloin steak, a yam. From there it was time to get dirty. Luckily, Melanie gave us an entire cookie pie the day before. I ate the entire deep-dish-8-some-odd-pound behemoth without even thinking twice. Subsequent CBL days, I’d have a pizza along with a more normal meal. After one training session I walked into a donut shop for the first time in a decade and order a dozen. I could only finish about 6 in the car ride home, but was able to eat  a real meal at home.

To be honest, there were some great take away points from this first phase of CBLing. I realized in my holier-than-thou tendencies with nutrition that I was under fueled with carbohydrates to support my training, which left me moody and irritable of tough days. In addition, I came to learn that my ketogenic cycles probably weren’t low carb enough to be optimal keto phases either.

Performance-wise I was on cloud nine. I felt like for the first time in ages that I had gas in the tank. I found staying keto outside of the carb feedings was easy. The “Pros” didn’t stop with performance either. I went to be every night feeling fat and happy, and I woke up feeling full and rested.

The “Cons” were obvious to me going in and I realized them right away. Just because you are CBLing doesn’t mean you are immune to the nutritional consequences of the foods you consume. News Flash: dairy and grains still cause inflammation. I woke up with mucus in my nose after the first day, which was very reminiscent of my childhood. Sneezing and “allergies” were simply part of the experiment, however.

Stay tuned for Part 3 where I talk about the “Clean” experiment, what all this means for you, and what I think about all this madness.
