My working ratios for cutting are ~ 40%pro/30%carb/30%fat (cant remember the order they usually go in for some reason lol...sorry)

On workout days i take in about 190g carbs. Thus far in my cutting, which has been very successful for some reason, i've been eating the same amount of carbs on my cardio days, just using brown rice or oats instead of Dextrose with a shake. The shake itself has 80g carbs, the rest are veggies, breakfast, and a little in pre. I've read a few things recently (not sure how i missed this) that non-lifting days in cutting should have lower carbs...

SO, my questions are:
1- How much should i lower my carbs by on non lifting days?
2- Should i increase protein and fat to make up for the difference, or only one or the other?

Thanks ^^

There is a dietting technique I use when cutting called seperation.

I only eat my carbs early in the day, and the last carbs I eat are right after a workout. And only eat fat in the after noon/night.

Its impossible to have zero carbs or zero fat, but keep it minimal.

Have a look thru Dr. B's articals in t-nation.

Fat and protein are good at the end of the day. Low carb cottage cheese, whey protein, EFA Oils (Flax, fish, Udo's..).
The fat slows down the digestion of the protein so consuming casein protein and high quality fats for your last meal is ideal because it will last the longest while you sleep.

So far so good, i knew all of that coming into this post =) Its just the non-lifting day carb lowering idea that i was posting about and that is still unclear.

I knew about early carbs, later fats, the P+F/P+C styles and what each does for you =) I hope that sort of clears it up

On cardio days I only consume less carbs because I don't consume my post workout shake..

Last post i'll have time for tonight, but....So would it be reasonable for me to simply drop the carbs from the shake (80carbs), and make up the calories elsewhere in another P+F meal or whatever i can come up with?

No - you still need your carbs in the morning, pre and post workout.

Indeed, that would be keeping the morning carbs, pre carbs, and post carbs, just no PWO shake... i'm pretty sure its a bad idea to consume right after a cardio session (remember, im ONLY asking about non work out days), and rather wait 1 hour then eat for metabolic burns to finish up.
