The P 1 is more flexible but still healthy fun eating. Before you start this meal plan, I recommend you complete the Basic 21 jump start first and follow the P1 start when done. All of these plans are made to fit your healthy lifestyle, not only for 21 days. All plans are created to balance your health and to prevent unwanted bad health. All of your foods you purchase for your meals will be NON GMO and Organic from your local food market
