Why Food Matters – Paleo/ Zone Diet

By January 3, 2015 No Comments

This Saturday we hosted a Nutrition Seminar for all members. Andrew explained Paleo and the Zone Diet. Our contention is that CrossFit is more than an elite fitness and conditioning program: CrossFit is a way of life. The lessons learned in the CrossFit gym are directly applicable to life outside the gym, including the kitchen! Therefore, we find it perfectly logical the word “diet” comes from the Greek root meaning “way of life” – and that eating in the “Zone” is a way of life that supports a healthy body and mind.

WHAT IS THE ZONE DIET?

The Zone Diet was created by Dr. Berry Sears. The Zone, which Sears debuted in his first book called “Enter The Zone” in 1995, is his term for proper hormone balance. Dr. Sears says that a 40-30-30 calorie ratio of low-glycemic carbs (mostly fruits and veggies) to low-fat protein has several great effects on the body. The first effect is that this ratio of nutrients causes the release of moderate amounts of the hormones insulin and glucagon. A secondary effect of significance to CrossFit Athletes is the 40-30-30 ratio also leads to fat loss, increased muscle mass and increased athletic capacity.

In addition to the 40-30-30 ratio, the other main aspect of the Zone diet is portion control. Athletes are allotted a certain number of “blocks” of food a day for their size and exercise level. A block, under the Zone system, is a balanced unit of food, composed of the following three sub-blocks: Protein (7 grams – i.e. one ounce of chicken, one egg, 1.5 ounces of fish.); Carbs (9 grams – i.e. half an apple, four cups of broccoli, one cup strawberries.); and fat (1.5 grams – i.e. three olives, three almonds, one teaspoon of olive oil.). According to the Zone, “average” men and women need 14 and 11 blocks per day, respectively, and a 6-foot 185-pound man would use 16 to 18 blocks. At CrossFit Rowlett, we encourage our Athlete’s to consume lean and fresh protein sources, and to eat only fruits and veggies as the source of carbohydrate. If you would like help finding your block prescription please ask Andrew or Mark!

Two examples of Zone friendly meals are below:

Meal #1: (4 blocks)
4 ounces chicken breast (4 blocks protein)
2 sliced apples Fuji (4 blocks carbohydrate)
12 almonds (4 blocks fat)

Meal #2: (4 blocks)
4 ounces lean meat or fish (4 blocks protein)
Large salad with broccoli, tomatoes, spinach and cucumber. (4 blocks of carbohydrate)
12 almonds (4 blocks fat)

For additional reading on the Zone diet, we recommend Greg Amundson’s article in the CrossFit Journal called CrossFit Journal Article #21.
