Just switched over to a modified (and soon to be 100%, I hope) primal diet and I box fairly seriously several times week, supplemented by running and weight lifting. I can manage the running and weights on my new diet, but I find that sustaining my energy during boxing workouts is trying. I get pretty light headed, prob a combination of fuel, the heat of the gym, etc. I don't usually eat before I work out but wondering if there's a magic bullet/snack that I might consider 30 mins or so before I train. I'm up at 5:30am and run to my gym, so my workout starts just after 6am. (Not much of an early morning eater, which is why it's posing a problem)
