The author was Alwyn Cosgrove, it was one of his ranting articles where he said something to the effects of “I’ve yet to see anyone lose large amounts of muscle on a diet”… While I tend to agree with the man on many instances, I think that the reason HE doesnt see it is because he manages his clients well.
Someone who might be doing it for a first time (like I did my first time) has a huge potential for muscle loss at many fronts. Someone who does low intensity, long duration cardio…coupled with 15 rep lifting on shitty exercises and then eats 1000 cals a day will DAMN SURE lose muscle. I doubt any of his clients are doing that though.
High intensity, short duration cardio(cardio may not be necessary while cutting…thats another debate), coupled with an appropriate diet(20% under maintenance or so) and a strength focused lifting cycle should help stave off most muscle loss. [/quote]
Yeah, that’s all true…to a degree. But one needs to realize that when decent training and a reasonable diet are controlled for, nutrient partitioning, whether gaining muscle or losing fat, is mostly a function of genetics. There are little things you can do, like macronutrient percentages, nutrient timing, specific training interventions, but these will pale in comparison to picking better parents.
If you’re one of those that gains a high percentage of muscle when you gain weight, be thankful. If not, gain slower and be more careful. Same goes for dropping fat…if you’re not one of those that can hang on to muscle easily, you have to slow things down.
