During INDUCT, you don't worry about caloric intake, you worry about HIGH FAT, Medium Protein and LOW CARBS at 20. As you move into OWL (ongoing wt loss stage 2) then you start to decrease fat, increase carbs at a gradual increase of no more than 5 carb a day per week until you find your CCL (Critical Carb Level).
