It's always been my understanding that when cutting, or at anytime really, calories should be lower on non-lifting days, due to the fact that less activity is taking place and as such, less calories are being burned or used.
However, it's also been my understanding that the body needs calories and nutrients to grow as well as maintain current muscle.
That being said, since it is widely held that muscle growth/repair doesn't happen in the gym, but at home while you rest, wouldn't it make more sense to actually feed the repairing muscles more so then, as opposed to on days you lift?
Just something I've never fully understood. Thanks for any input.
