Our recommendation to “eat meat and vegetables, nuts and seeds, some fruit, little starch, and no sugar” is adequate to the task of preventing the scourges of diet-induced disease, but more accurate and precise prescription is necessary to optimize physical performance. Finely tuned, a good diet will increase energy, sense of well being and acumen, while simultaneously flensing fat and packing on muscle. When properly composed the right diet can nudge every important quantifiable marker for health in the right direction. Diet is critical to optimizing human function and our clinical experience leads us to believe that Barry Sears’ “Zone Diet” closely models optimal nutrition. The best athletic performers are Zone eaters. When our second tier athletes commit to “strict” adherence to the Zone parameters they generally become top tier performers quickly. It seems that the Zone diet accelerates and amplifies the effects of any intense workout regimen.
Unfortunately, the full benefit of the Zone diet is largely limited to those who have at least at first weighed and measured their food. For a decade we’ve experimented with sizing and portioning strategies that avoid scales, and measuring cups and spoons only to conclude that natural variances in caloric intake and macronutrient composition without measurement are greater than the resolution required to turn good performance to great. Life would be much easier for us were this not so! The “meal plans” and “block chart” below have been our most expedient approach for eliciting the Zone’s best offering in athletes. Void of theoretical or technical content this portal to sound nutrition still requires some basic arithmetic and weighing and measuring portions for the first week. Too many athletes after supposedly reading “Enter the Zone” still ask, “So what do I eat for dinner?” They get meal plans and block charts. We can make the Zone more complicated or simpler but not more effective. We encourage everyone to weigh and measure portions for one week because it is supremely worth the effort, not because it is fun. If you choose to “guestimate” portions, you’ll have the result of the top athletic performers only if and when you are lucky. Within a week of weighing and measuring you’ll have developed an uncanny ability to estimate the mass of common-food portions, but, more importantly, you’ll have formed a keen visual sense of your nutritional needs. This is a profound awareness. In the Zone scheme all of humanity calculates to either “2”, “3”, “4”, or “5 Block” meals at breakfast, lunch, and dinner with either “1” or “2 block” snacks between lunch and dinner and again between dinner and bedtime. We’ve simplified the process for determining which of the four meal sizes and two snack sizes best suits your needs. We assume that you are very active (both in the gym and outside of it). Being a “4 Blocker”, for instance, means that you eat three meals each day where each meal is comprised of 4 blocks of protein, 4 blocks of carbohydrate, and 4 blocks of fat. Whether you are a “smallish” medium sized guy or a “largish” medium sized guy would determine whether you’ll need snacks of one or two blocks twice a day.
The “meal plans” stand as examples of 2, 3, 4, or 5 block meals and the “block chart” gives quantities of common foods equivalent to 1 block of protein, carbohydrate, or fat. Once you decide that you need, say, “4 block” meals, it is simple to use the block chart and select four times something from the protein list, four times something from the carbohydrate list, and four times something from the fat list every meal. One-block snacks are chosen from the block chart at face value for a single snack of protein, carbohydrates, and fat, whereas two block snacks are, naturally, chosen comprised of twice something from carbohydrates combined with twice something from the protein list, and twice something from the fats. Every meal, every snack, must contain equivalent blocks of protein, carbohydrate, and fat. If the protein source is specifically labeled “non-fat”, then double the usual fat blocks for that meal. Read “Enter the Zone” to learn why. At Zone parameters body fat comes off fast. When our men fall below 10% towards 5% we kick up the fat intake. The majority of our best athletes end up at X blocks of protein, X blocks of carbohydrate, and 4X or 5X blocks of fat. Learn to modulate fat intake to a level of leanness that optimizes performance. The Zone diet neither prohibits nor requires any particular food.  It can accommodate paleo or vegan, organic or kosher, fast food or fine dining, while delivering the benefits of high performance nutrition.
