The second phase of the Atkins diet moves into ongoing weight loss. It involves slow introduction of foods with carbohydrates that also are considered nutrient dense. Most of the carbohydrate calories come from vegetables. Atkins dieters still eat a higher proportion of proteins and fat, but they gradually add more carbohydrates into the diet. According to Atkins, the purpose of the phase is to continue to burn and dissolve fat while maintaining appetite and craving control. This phase also introduces the dieter.

to a broader range of foods and helps to determine the dieter’s threshold level of carbohydrate consumption. It is the intention of this phase to deliberately slow weight loss.
If weight loss continues, carbohydrate intake is gradually increased each week. In week one, the dieter can add 25 grams of carbohydrates per day. In week two, 30 grams of carbohydrates are allowed. This addition of five grams per week continues until weight loss stalls, then the dieter drops back to the previous gram level. Typical tolerance levels may range anywhere from 30 grams to 90 grams per day. Atkins literature says that the more a dieter exercises, the more carbohydrates he or she can tolerate. The Atkins diet recommends choosing carbohydrates first from vegetables that are low in carbohydrates, then from other sources that are fresh foods high in nutrients and fiber. Examples of low-carbohydrate vegetables are lettuce, raw celery, and cucumbers. Nutrient-rich carbohydrates are green beans, Brazil nuts, avocados, berries, and whole grains.
