heres how it works.
on days that your carbs or fats are cycled down you take those cals and 'over feed' on protein.
simple example
normal day
protein 200
carbs 100
fats 50
= 1650 cals
a protein over feeding carb cycle day
Protein 300
carbs 0
fats 50
= 1650
cals are the same both days. but being the protein has went up by 100 , the thermic effect of the protein puts you in a further deficit on this day (but still eating the same amount of food).
you'll more then "meat" (pun intended) all your protein and amino acid demands for muscle tissue preservation. . but, worried about being no carb while not in ketosis ? no worries, your body will convert some protein to glucose via gluconeogenisis if the glucose needs and energy demands are there (and this is metabolicly taxing as well and has a cal deficit effect too).
so on this day you'll still eat what appears to be the same amount of food and consume the same amount of cals, but you'll be in a further calorie deficit and burn through more of those cals (30% more cals burnt from what went over to protein from carbs, plus the metabolic stress added for converting any protein over to glucose).
through your diet itself your putting more energy demands on your body and putting yourself in a further net deficit (just like cardio would do)
I'll touch on these things a bit further when I get a chance.
note : your 'over feeding' on protein on these days. and if need be your body is converting this extra protein into energy to be burned up as glucose as well.
this puts you in a further deficit then simply consuming carbs as an energy source
