What are the different phases of the Atkins Diet?

There are four different phases to the Atkins Diet: induction, ongoing weight loss, pre-maintenance, and maintenance. Induction is the most restrictive phase and is typically followed for two weeks. During this phase, carb intake is limited to 20 grams per day. The other three phases gradually increase carb intake until you reach your goal weight, at which point you enter maintenance and consume a moderate amount of carbs daily.
