Ok, so I already know that its not the best idea to try and do both at the same time, but I was checking a board yesterday where they were saying that they do it without problem (albeit over a period of say 15 months).
The argument revolved around the use of carbs and protein.
My thought was that in order to build muscle you need protein. But if you're trying to create a calorie deficit, and thus ingesting probably less carbs, the shortage in carbs will be offset by production of glucose from protein available. Only if there is insufficient protein and carbs (ignoring ingested fat to keep it simple) will the body hit fat stores for fuel. Is this correct? Or would the body prioritise muscle and use up the protein availble to repair that and THEN is theres any left give it up for glucose production?
(Or none of the above?)
