The Atkins 20®, the original low carb keto diet is split into four phases. You’ll begin in Phase 1, consuming the smallest amount of net carbs to burn fat and put your body in ketosis. As you move through Phases 2 and 3, we’ll keep you on track by gradually balancing and expanding your list of acceptable foods. By Phase 4, you’ll be able to eat at your maximum net carb level while maintaining your weight and lifestyle. How to Calculate Atkins Net Carbs Atkins products have been tested to ensure that their impact on your blood sugar level is minimal. The majority of Atkins products can be suitable for Phase 1 as long as you don’t sacrifice the intake of foundation vegetables (the requirement is 12 to 15 net carbs daily). If you are in Induction, you have 5 to 8 grams of net carbs to use for dairy, dressings, or Atkins products. You can plan accordingly and customize your diet to your needs!
