Week 1 tips for success:

  • Load up your plate with Non-Starchy Vegetables: They make a great snack if you’re hungry and can bulk up any Nutrisystem meal.
  • Enjoy zero-calorie beverages like black coffee, unsweetened tea and flavored seltzer water. Aim for 64 ounces (8 cups) of fluids daily.
  • Free Foods are allowed in Week 1: Add unlimited flavor to your meals and veggies with spices, herbs, lemon juice, hot sauce, vinegar and more.
  • Try to limit your physical activity in Week 1. This gives your body time to adjust. If you have been exercising prior to starting Nutrisystem and would like to continue during the first week of the program, we encourage you to reach out to a Weight Loss Coach to discuss your exercise in more detail.
  • Space your meal and snacks 2-4 hours apart.
  • Hearty Inspirations premium meals are not recommended for Week 1.
