my good friend protein

Chris Sturr, with whom I’ve shared many a fondue pot (so you know this is not too serious), recently suggested through J-P that I try the Zone Diet concept to make sure I get enough protein to prevent the cranky shakes. Basically, you think of foods as “blocks,” with 7 grams of protein equaling a block of protein, 9 grams (not counting dietary fiber) for a block of carbs, and 3 grams for a block of fats. You try to keep those blocks in a 1:1:1 ratio, and eat totals that bring you up to daily intakes recommended based on your lean body mass and activity level. Fair enough.

My biggest beef is not with the pseudoscience crufted around the basic idea (unavoidable in nutrition writing), but with the books’ inherent bias toward meat eating. To make it easy for you–so that you don’t have to “gram it out”–the books call certain amounts of meat or dairy “protein blocks,” with all greens and all beans except soy classed as “carb blocks.” What about spinach? It’s 1 protein to 0.4 carbs. Or broccoli and cauliflower, each about 1:1 (slightly in favor of carbs). Lentils and split peas, the same. And the rest of the beans aren’t so bad: 1:1.3 for black beans, 1:1.75 for chickpeas. Not that I’m going to go hippie, but Dr. Sears would have me eat three quarters of a pound of boneless, skinless chicken breast each day–and I’m not about to do that, either.

Speaking of skinless: I also routinely go way over my daily allotment of fat. But my cholesterol is fine, and my estimated body fat percentage is a couple of points below their “ideal woman.” It doesn’t seem to be hurting me.

Complaints aside, I will keep a food diary for a little while, to see what tweaks I can make, and whether coming closer to 1:1:1 has any noticeable effects. If I find anything interesting, I’ll let you know.
