I'm not sure where this post would go so I put it in this forum.
Anyway, I've recently decided that I want to lose some fat. I'm probably around 18% bodyfat and would like to get down to around 12%. I lift heavy weights in the afternoons (around 6 PM) and never have the motivation to do cardio after that. I'm thinking about waking up a little earlier before work and running a mile or so every day during the week.
I've always read that cardio can contribute to some muscle loss. My question is: what should my morning diet be if my goal is to maintain as much muscle as possible? Should I eat my normal weight loss diet of high protein low carbs, or should I add in more carbs prior to running? My main concern is doing cardio after sleeping for 7 hours is really not going to leave my body with much to burn besides muscle.
