What is the One-Week Reboot?

With your Nutrisystem order, you’ll follow the One-Week Reboot for your first week on the program. This first week is lower in calories and designed to jumpstart your weight loss.*

  • You will receive a specially designed Week 1 Guide to help maximize your results.
  • During your first week, you will eat Nutrisystem® breakfasts, lunches, dinners and snacks for all 7 days. You can choose any meal or snack from your entire order to enjoy during this first week.
  • You will receive 7 Nutrisystem® shakes to use as your morning snack during this first week. These are packed with protein and probiotics to support digestive health and help shrink your belly as part of a balanced diet and healthy lifestyle.

Once you’ve completed your first week, you’ll enjoy a Nutrisystem® breakfast, lunch, dinner and snack, plus grocery items like PowerFuels, SmartCarbs and veggies. You’ll also incorporate Flex meals and snacks. This can all be found in your Quick Start Guide included in your box as well.
