This is totally incorrect . Atkins induction includes 20 grams of carbs/day which are REQUIRED in the form of vegetables and salad. After induction 5 grams of carbohydrates are added per week or two until you reach your criticial carbohydrate level (the level at which you stop losing). For some people it's as high as 100g/day. For most it's in the 35-40/day range.

Actually PPLP is considered a moderate carb plan. It allows 30g/carbs per day if you have 20% or more to lose and 55g/day if you have less than 20% to lose.

Other differences are that Atkins discourages caffeine and alcohol; Protein Power allows them. Both discourage the use of aspartame but do allow the use of sucralose.
