On January 1st, I launched a new nutrition experiment based on Mark Sisson’s Primal Blueprint. After 30 days of no grains, no dairy, and no legumes, the question is: What happened?
First off, doing a significant dietary change isn’t easy. I love my homemade corn tortillas and my wife’s gluten-free scones, muffins, and pancakes. I love butter. I like half-n-half in hot coffee. Cheese is a convenient and easy snack. No rice and beans at a Mexican restaurant? You’ve got to be kidding! But I stuck with it for the sake of the experiment.
I tracked everything I ate for the month in myfitnesspal (free, and allows for inputs on the web, iPad app, Blackberry app – everything that I use!). I didn’t track my food for calorie counting purposes, but to look for total macronutrient breakdown as well as to potentially find links between what I ate and how I felt.
The recommended intake for macronutrients as a percentage of calories (at least according to myfitnesspal) are 55% carbohydrates, 30% fat, and 15% protein. On a diet of basically meats, vegetables, fruits, and nuts, my macronutrient makeup was:
- Week 1: 24% carbs, 54% fat, 22% protein
- Week 2: 27% carbs, 51% fat, 22% protein
- Week 3: 32% carbs, 47% fat, 21% protein
- Week 4: 30% carbs, 52% fat, 18% protein
- Current week-to-date: 30% carbs, 51% fat, 19% protein
What?!? Greater than 50% of my calories came from fat? Get the AED device and statin drugs, quick!
Sorry. The science simply doesn’t support the cholesterol myth. Besides, at my last check, after I’d made the first big change in my eating habits to eat least clean 6 days a week, my cholesterol markers were all well within standard guidelines (much different than they had been in the past on a grain and sugar-heavy diet).
How did those macronutrient breakdowns happen? Did I get a target from a Paleo Diet website and work to follow it? Nope. I ate meats, vegetables, fruits, and nuts and that’s how it came out. Did I purposely seek out more dietary fat? Nope. I just don’t fear it. I ate whole (and usually organic) foods until I was full, letting the chips (that I didn’t eat) fall where they may.
So what happened with the experiment?
Most people would want to know whether or not I lost weight. That wasn’t what I was going for, but it was a nice side benefit. I ended up losing 12 pounds over the month, dropping from 224 on January 1st (I had gotten a little sloppy since the end of the sugar-free summer experiment) to 212 on January 31st. 212 is the lowest weight I’ve been at in over 20 years.
For me, however, the experiment was about what it would do for my skin. I have seborrheic dermatitis that I was looking to clear up without applying a prescribed steroidal cream. Steroidal creams can have an effect of thinning the skin over long-term use, and that didn’t sound good to me. So I looked to nutrition for a potential answer. Based on a clean diet for the month of January, I’d say it’s a success. My skin is more clear that it’s ever been and I’m not experiencing red, patchy flareups at all. Early into the experiment, I did allow about 1/2 tablespoon of shredded cheese to enter my diet and within 2 days, I had very painful flareup. It cleared quickly and hasn’t come back.
From here, it’s hard to even want to experiment with bringing things back to see if I can identify the exact trigger. Besides, my wife already eats gluten-free, dairy-free and it makes sense within the family to be more aligned in our diets. But, Superbowl Sunday is coming up and I’m thinking about throwing all caution to the wind, eating a bunch of crap like I did last year by punishing my body with about 5500 calories and getting back on track the next day. I haven’t had a “cheat day” in a while, but with results like feeling better, losing weight, and clearing skin, it’s hard to want one.
