we know that slow dieting is the best way preserve muscle while cutting. 500 cal deficit should equal 1lb bf weekly. I read a article and can't seam to find it , but it says you can do extreme dieting for a week only and you will not loose muscle. Any longer you will loose a significant amount of muscle. Does anybody know the facts behind this? So hypotheticaly speaking you can do a 500cal deficit for a few weeks then once throw in a very low cal week your total fat loss would be greater and muscle retention would remain the same.
