P90X Nutrition Plan

The P90X Workout Program, created by fitness trainer Tony Horton, contains dual focus: fitness and nutrition. A specific P90X Nutrition Plan is included in the workout program to optimize results and make over your body in just 90 days.

The Premise 

The P90X Nutrition Program consists of three phases that take place over a 13-week period. In each phase, you have the option to follow the meal plan (use the included sample menus and recipes) or the portion plan (create your own meals following the included food serving guidelines). The phases in the P90X Nutrition Program are as follows:

Fat Shredder – Phase One

In this phase, you’ll up your protein intake to aid in burning fat and building muscle. Of all the phases in the nutrition plan, this one allows for the lowest daily caloric intake. Expect to consume mostly lean protein and vegetables.

Energy Booster – Phase Two

During phase two, you’ll begin reincorporating complex carbohydrates in your diet. The idea is to give you a boost in your stamina and endurance during the P90X workouts you’ll be doing in conjunction to this diet. Lean protein is still heavily emphasized during this phase, though you’re allowed to eat three servings of complex carbohydrates like whole wheat pasta, oatmeal and fruit (just so long as the fruit is low on the glycemic index).

Endurance Maximizer – Phase Three

The amount of complex carbohydrates you’re allowed to eat in this phase increases to aid you in your workouts. Again, the emphasis is on lean protein and clean foods.

The Diet

Besides the emphasis on phases, the P90X diet allows you to eat natural foods that don’t contain any artificial ingredients or unhealthy ingredients (like high fructose corn syrup, refined sugar and white flour). Suggested foods are categorized as follows:

  • Lean Proteins: chicken breast, turkey meat, fish, egg whites
  • Complex Carbohydrates: oatmeal, whole wheat bread, whole wheat pasta
  • Fruits and Veggies: organic varieties are best, fruit should be low on the Glycemic Index (cherries, grapes, oranges)
  • Dairy: low fat milk and cheeses
  • Condiments: low fat dressings and spreads like natural marinades, mustard and honey

Snacks are allowed and should fit in the confines of the suggested foods. Water is very important–you should make an effort to drink it regularly, especially with the vigorous workouts you’ll be doing.

Things to Consider

The overall P90X plan requires extreme commitment and dedication. You have to be ready to give 100% and make a drastic lifestyle change. This isn’t just counting calories or cutting soda from your diet. 


Most people will not be successful on this program. The intensity makes it very easy to give up after a week or two. The P90X Nutrition Plan and Workout Program is best for someone who has already established a basic fitness and healthy eating regimen and is ready for a super-charged lifestyle makeover.
