Losing muscle on a cut a myth?16674

nine0seven private msg quote post Address this user
So from a scientific standpoint, fat is a stored energy source. Therefore our bodies will burn fat before it even touches muscle. So is the whole "lose muscle on a cut" a myth? I'm thinking, unless you starve yourself for 2 weeks, you shouldn't lose any muscle at all, right?

pretty sure it's not that simple but eknight will be able to explain it better.

You'll lose it if you're on too drastic of a deficit.

True but wouldn't our bodies burn the fat before it burns muscle?

I personally believe you do lose some muscle in a long cut (16+ weeks). I also believe that if your diet is right and you incorporate hiit as your choice of cardio then the amount of muscle lost is so minor it doesn't really matter.

But call me crazy in that I believe that you can also gain a small amount of muscle while cutting if things are done correctly. That's my opinion and I know it's not one that many people agree with because the whole calories in vs calories out deal. But if you are optimizing hormone levels though proper food choices and on a strength building routine that is seeing results in numbers then why not believe you could possible gain a small amount of muscle mass while cutting. Personally I've done it

Hate spoon feeding stuff, so let me see if I can lead y'all in the right direction. What is muscle (all tissue, really) composed of? -3X

Glycogen. So the loss of water and glycogen stores leads to strength loss and muscle volume, but not necessarily muscle tissue.

Yep, a moderate deficit does that. You can only burn so much fat in a given time, however, so if you cut too much your body has to burn something.

I agree with everything everyone else said, too. A lot of people get flat and lose size but aren't actually losing muscle, they just think they are. Or diet too fast and do lose it lol.

@GrizzlyBerg (and technically @Arimac44 too, since aminos require N) is correct. We need amino acids to repair tissue (among thousands of other functions in the body). So let's say you're cutting, and your calorie deficit is too great (remember- it's estimated that you can only oxidize a maximum of 31 kcals per day per pound of body fat). You have maximized the amount of fat you can burn in a day, but... Uh oh! Your body still needs glucose to survive and you've utilized your dietary glucose intake (and the foods that break down to glucose). Where is your next source of glucose? Protein- as in tissue. The problem is, that conversion is reallllllllly inefficient. How inefficient? You lose around 1/3 of the protein you're converting to glucose in the actual process of gluconeogenesis. So, in order to fuel your nervous and immune systems, you are having to get the energy source from somewhere, and that somewhere is muscle, and you're doing it in a way that further compounds your energy deficit.

Now that's an extreme situation, BUT it still can, and does, happen to a lesser degree if dietary protein is inadequate or if your deficit is even a bit too great.

So, no, losing muscle on a cut is not a myth. -3X

What would you classify as a too great deficit?

@nine0seven. Even if its a myth which is not. you will not loose but will not gain muscle since your body needs something to recover.

I have been cutting for 3 months now using high fat moderate protein and lots of fibrous carbs (non starchy vegetables) as only carb source. First time I've tried to 'cut' as I'm still relatively new to bodybuilding, but my experience has been once over the first week of coming off carbs as a main energy source, you adapt and energy levels are just the same if not better. I have so far lost in excess of 30lbs and maintained strength, with recent very small increases in strength on some exercises. I think it is vital to consume plenty of calories through fat (good oils, cheese, advocados etc) and drink lots of water otherwise you will feel sluggish. I'm not saying ive gained or lost muscle as I have no means of accurately measuring this, it's just my opinion. oh, and no cardio for me either.
