Background Information on the P90X2 Nutrition Guide Phases, Levels and When to Change The terms Level and Phase are important to understand. The term Level relates to the amount of calories youll be taking in. The term Phase describes the ratios of carbs/protein/fat that change during the progression of the P90X2 diet. Levels are categorized as A (1,800 2,399 cal/day), B (2,400 2,999 cal/day), and C (3,000 + cal/day), while Phases are I (50% protein/25% carbs/25% fat), II (30% protein/40% carbs/30% fat), and III (25% protein/50% carbs/25% fat). Lets start with Levels. Its very important to get this right and to customize the amount of calories youll be taking in to your specific needs. The P90X2 calorie calculator weve incorporated into our spreadsheet takes into account your Daily Activity Burn (DAB). It also takes into account the average caloric burn for a P90X2 workout. This highlights the importance of having a heart rate monitor that gives you calorie burn. Another very good reason is that so you can evaluate your progress using a Performance Based Assessment (see below). Finally, the calculator allows you to incorporate a calorie deficit to encourage weight loss or add calories to encourage weight gain. Again, it is important that you know your goals from the outset. Contact us for help with your calorie calculations if you want some advice. As youll see the P90X2 diet changes as the intensity of your workouts increases. Why? The answer is related to a substance called glycogen. Glycogen is essentially converted glucose (sugar) and it is the bodys first line of energy at high intensity exercise. It is created when the body takes in carbohydrates, which are a form of sugar (please forgive this gross oversimplification of this essential metabolic process). When you workout at a lower intensity (judged by your heart rate) your body burns more fat, and less glycogen. However, when you workout at a high intensity, particularly at or near your anaerobic threshold, you burn more glycogen. The P90X2 Nutrition Guide acknowledges this fact and anticipates the additional need for glycogen as the P90X2 workout becomes more and more intense. Accordingly, it responds by increasing carb intake. Thats all good and well, but dont be in too much of a rush to jump into Phase III of the P90X2 diet. Glycogen is stored in the muscles and liver, but they have limited storage capacity. The fat cells are the only other place that the body can store excess glycogen. So, if you are taking in a lot of carbs, but not working out at a high intensity, you are much more likely to gain weight. Thats really why the US is in an obesity crisis. We are taking in too many carbs. Its sugar thats making us fat. So, be sure you are using a Performance Based Assessment and, if necessary, consulting with a Team Beachbody Coach that can help you sort this out. Taking in too many carbs can negatively impact your results, so this is important to get right. Standard, Vegan and Grain Free The Standard version of the P90X2 diet is just what it sounds like. Its pretty standard. It includes meat, grains, and dairy. Its all pretty standard healthy stuff. If you eat everything, this is probably going to be the most manageable one for you. The Vegan version excludes meat and dairy. You may not think you can do P90X2 as a vegan. Personally, its not my thing either, but Tony Horton was a vegan for over 10 years. He then transitioned into vegetarianism and currently eats very little fish and chicken and the occasional egg. So, its very doable and the P90X2 Nutrition Guide provides the road map. Finally, we have the Grain Free option. This is the closest version to the Paleo (or Primal) nutritional philosophy, which is what I subscribe to ( recipes here ). The Grain Free option includes dairy, which would be one of my criticisms of the plan (there are others, including the inclusion of Canola Oil and the absence of Coconut Oil and a few other things on the Food Lists). In January of 2009 Tony Horton encouraged me to quit dairy for 30 days and see how I felt. I felt better, so I kept going with it. There are a lot of easy substitutes for dairy and we are working on developing a Grain Free/Dairy Free option of the P90X2 diet. Along these lines, please feel free to experiment a bit with you nutrition. Try new things and pay close attention to how you feel. For many people, this way of eating will be entirely new. Allow yourself to make mistakes. Its a learning process, so let it be that. In time youll find foods that are healthy, and that you enjoy eating. It might be frustrating, but it will be worth the time and effort. The Resources The Spreadsheet This is very similar to what we put together for P90X, but youll see that weve changed up a few things. First, weve incorporated the P90X2 calorie calculator, which is more accurate than the original P90X calculator. In addition, weve incorporated the Standard, Vegan and Grain Free versions of the plan. Weve also made it easier to adjust your daily portions. Each Level/Phase has the total daily calories added up and then provides you with a spot to enter your Snacks. This was something that people really struggled with and we hope weve made it easier.
