Pre-Maintenance
Atkins diet pre-maintenance phase make the transition from weight loss to weight maintenance by increasing the daily carbohydrate intake in 10 gram increments each week so long as very gradual weight loss is maintained.
Daily net carbohydrates intake is increased again this time by 10 grams each week from the latter groupings, and the key goal in this phase is to find the "Critical Carbohydrate Level for Maintenance", this is the maximum number of carbohydrates you can eat each day without gaining weight. This may well be above the level of carbohydrates inducing ketosis on a testing stick. As a result, it is not necessary to maintain a positive ketosis test long term.
