I have trained DC style under SuperD at IM (very successfully may I add, God Bless that man haha) and have always (whether bulking or cutting) seperated my meals into P/F and P/C. I think that helps me a lot as far as keeping track of my overall macros/calories and also keep some excess adipose off.
The main reason I ask during cutting is because since I am in a caloric defecit anyway, will my body still be able to utilize the nutrients without storing fat as it would when taking excess calories above maintenance. I also thought that since fats slow digestion, maybe that would also allow my body longer amout of time to utilize the nutrients ingested.
Obviously these meals would not contain a large amount of both C/F, but would there be and benefit of having a small amount of both or would this just deter the fat burning process?
