As Kristine noted, SP deals with hormonal balance and once your hormones are balanced, everything - including fat loss - will fall in to place. Ketosis is not part of the SP plan. With PP it's not discussed but it definitely happens. PP is a ketogenic diet.

15 grams of carbs per meal are allowed on Schwarzbein. PP starts at 30 grams a day and you figure out what your adequate protein intake is for a day.

The link to a synopsis of the plans is here. They also have websites with more info.
