Nutrition is Our Academy’s Foundation

Nutrition is the foundation to the CrosFit I-5 program. We believe proper nutrition is the foundation to optimal performance. The food quality, portion, combination & timing of consumption all have an impact on ones daily performance.

Food is a drug and can influence the way we feel, sleep, & perform. 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, mental sharpness, 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. CrossFit’s best 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 the CrossFit training regimen.

The Truth about the Low Fat Fad

For several decades now, bad science and bad politics have joined hands to produce what is arguably the most costly error in the history of science – the low fat diet. This fad diet has cost millions unnecessary death and suffering from heart disease, diabetes and, it increasingly seems, a host of cancers and other chronic and debilitating illnesses. Modern diet and nutrition habits have inundated our society. Advances in agriculture and food processing have resulted in health problems for modern man. Heart disease, diabetes, cancer, obesity & psychological dysfunction have all been scientifically linked to diets high in refined or processed carbohydrates and low in fat.

The CrossFit Nutrition Prescription

Protein should be lean & varied and account for 30% of the caloric load. Protein should be the foundation of each meal. With each meal you should consume a palm size portion of lean protein.Carbohydrates should be predominantly low-glycemic and account for about 40% of your total caloric load. If you are looking at a plate of food, 2/3 of your plate should be full of colorful vegetables. Fat should be predominantly monosaturated and account for about 30% of your total caloric load. Try to add a portion of avocado, almonds or olive oil to each meal.

So what should I eat?

In plain language, base your nutrition on garden vegetables, especially green, lean meat, nuts and seeds, little to no starch and sugar. That’s about as simple as we can make it. Many have observed that keeping your grocery cart to the perimeter of the grocery while avoiding the isles is a great and simple way to protect your health.

What foods should I avoid?

Excessive consumption of high-glycemic carbohydrates is the primary culprit in nutritionally caused health problems. High glycemic carbohydrates are foods that raise blood sugar too rapidly. They include rice, bread, candy, potatoes, soda and most processed carbohydrates. Processing can include bleaching, baking, grinding & refining. These are foods that increase insulin levels in the body. Although insulin is an essential hormone for life, chronic elevation of insulin levels has been linked to obesity, elevated cholesterol levels, blood pressure, and mood dysfunction.

It’s not just about looking good… Although that WILL happen too

Let’s face it; most people don’t join a gym to get healthy. Usually, it’s because they’ve gained some weight and want to fit into those pair of jeans again. The CrossFit training program is not solely about losing weight or toning up for looks. There are no crash diets in our program. We focus on perfecting your skills and movements and improving your athletic performance from class to class. It’s about getting stronger, faster, more agile and confident that you are literally prepared for anything life can throw at you. It’s about believing you can do something you’ve never done before. It’s about consistent athletic improvement. It’s about health and feeling great. It’s about life. The good news is “looking good” is a byproduct of all these!
