Unless you are performing extreme aerobic work you will not burn muscle per se. The problem with aerobic work relative to size and strength, and this is irrespective of caloric intake, is that it and resistance training essentially elicit the opposite adaptation by the skeletal musculature. So, to optimize results from either form of training requires the exclusion of the other. You can do both and achieve good results, so it all comes down to Jack of all trades, master of none and what you want from your training.
