I'm coming towards the end of my cutting cycle - so I've upped my cardio to 6 - 7 times a week, around 35 - 45 mins, doing a jog/walk combination, in the morning. I've done this regime earlier this year, but even though I lost fat, I seemed to lose an equivalent amount of muscle too. (I was working out 5 times a week, and still am)
Back then I didn't eat for 45 min - 1 hour after my cardio (too keep insulin levels low) because I wanted to take full advantage of EPOC (Elevated Postworkout Oxygen consumption) - hence burn more calories. In hindsight, maybe that was the reason for the muscle loss (also I was on a daily calorie deficit of 700 - 800 cals)
So this time around, after cardio, I'm considering having half of what I usually have post-workout. I'm aware this will hinder fat oxidation, because of the insulin spike resulting from the consumed glucose. But maybe this will preserve most of my muscle mass ? Another possibility is just supplementing with Amino's, BCAA's, or Glutamine after cardio - which could be the protein source for gluconeogenesis, instead of muscle protein being used ? [/color]
Any ideas or thoughts would be appreciated.
