Do you actually lose muscle on a calorie defecit?

[Vidiot]

I haven't really seen much proof but I'm still worried about it. I've been taking nutrition at the college (BEST CLASS EVER! I highly suggest you all take it. You'll realize you've been doing it wrong this whole time)

Anyways I'm thinking that you don't really lose muscle unless you are <10% body fat. Fat has 9 calories per gram, why would your body take muscle and go through the complex process of converting it to energy especially when it's 4 calories per gram? Doesn't make sense. The "muscle" that people think they lose when they are cutting is probably some fat around the muscle fibers and water.

Just my 50 cent ( :P )

[batman-42]

dietary fat has 9 cal/g, not body fat. and protein has 4 cal/g, not muscle

and yes you do lose muscle on a cut. if you do it right you wont lose a significant amount

I just don't see why your body would lose muscle. Doesn't make sense. Protein is not a good source of energy.

Then how should I do it exactly right? I need to cut and I don't want to lose my gains :|

Then how many calories per gram of body fat are there?

[7399martyn]

yes, a big calorie deficit like 1,500 below maintenence will make you lose a noticable amount of muscle.

well obviously not that. I'm talking around a 500-700 deficit

protein and muscle are not the same thing, and try 300-500 under maintenance

[chiraag]

try the anabolic diet

I don't believe so, muscle is very precious to the human body, so unless your starving yourself for several weeks, it's not gonna happen on a small calorie deficit.

[LukeN.Good]

Had you been doing the research yourself, you wouldn't have been doing it wrong in the first place.

Body fat and dietary fat yield the exact same coloric values. You're confusing it with the "calculation" of stored body fat, in which case you exclude an estimated amount of other various contents making up fat cells. (Same goes for the amino acids derived from muscle tissue.)

The values of the molecules themselves do not change.

that's what I thought

do you have a good link? All I see is a ton of advertisements and other random shizzle. I just wanna see how to do it/what it is lol

Lol, I think he means 'caloric'.

Muscle is the opposite of precious to the human body! Your body hates putting on muscle, it increases the amount of calories your body needs to function. When you put on muscle you are fighting against hundreds of thousands of years of genetics that have been primed to store as much fat as possible and keep muscle mass low (myostatin gene). This is why when you go on a large calorie deficit muscle mass is the first thing to go, as less muscle mass = more efficient body energy wise.

However, going on a small calorie deficit will minimize this, NOT prevent it.

you dont lose **** all if you do it properly

Muscle isn't precious, your body only requires a small amount, the body prefers fat because it keeps you warmer and protects organs.

"The human body is one of the most intelligent living forms in the universe, and it will NOT injure precious muscle tissue to use as fuel unless it's survival is threatened. Even during prolonged fasting or starvation, the body sets priorities. When the body has exhausted the use of glycogen and fat stores as energy, muscle protein is the first to be catabolized."

If muscle was precious to the human body, everyone would be big and ripped without any training.

If cardio and a slight calorie deficit burned muscle, the human race would've been extinct a long time ago.

[shot_gun]

you dont lose muscle unless you are 10% body fat or lower?
idk if thats what you meant, but i eat around 4600 calories, and my body fat (fast metabolism) stays very low all the time, right now its around 7-8% and im actually packing on muscle pretty quick in the past few months.

[1111111111111111111111111111]

You will always lose at least a small amount of muscle when dropping bodyfat, more or less depending on your genetics.

[user7878778786]

if done right you should hardly lose any muscle.

[LukeN.Good]

coloric? lol

*Caloric. Thanks for handling that typo so maturely.

[Vidiot]

you all keep mentioning "if done right". Define that.

Do you mean:

1. A low calorie deficit not exeeding 700 calories below maintenance or somewhere around there
2. Keep lifting weights to promote muscle gain
3. High protein diet

Do all 3 and you will hardly lose any muscle?

[Nereis]

I'm going to have to chime in here as I'm on a cut myself. Firstly, consider everything your college professor tells you false until it's verified by another source like a scientific journal. Secondly, I'd advise you to read Lyle McDonald's work before starting your cut. It IS possible to cut with a large calorie deficit and lose minimal muscle. But you will be perpetually tired, cranky and hungry most of the time, and it's unadvisable unless you work a desk job and all you ever do is sit down and go to the gym a few times a week. Plus, you're going to get tired of chicken breast, egg whites and brocolli pretty damn quick.

[Teledin]

if done right you should hardly lose any muscle.

This. If you time your nutrient intake correctly and ensure to replace any carb depletion with adequate fat and protein intake, you really shouldn't lose any muscle at all - and with that said you can obviously anticipate the lower your body fat drops the more rapidly muscle will be broken down.

Key points to remember is macro nutrient intake is just as important as the overall caloric deficit. Get those right and any muscle wasted in the cutting phase will be regained very quickly once you start going into a surplus of calories again. Hence why in the first few weeks of a bulk succeeding a cutting phase, guys can gain up to 4kg in body weight (water retention, muscle, etc.) within a couple of weeks without putting on any fat and in fact looking a lot leaner.

However you want to also ensure you're lifting relatively heavy during a cut phase to make sure your body knows it needs to keep its muscle to push/pull the load.

[fitnessnewb]

I dont believe horse **** that you will lose considerable amount of muscle as long as you stay lifting hard. I am on a cut atm and I all my lifts are going up while I am dropping about 1lbs a week. What is the use for the body to get rid of the hard earned muscle if the body specifically stored FAT for reserves when it needs the calories??? It just doesnt make sense.

your actually super super wrong on this one buddy.

ok 1)protein turnover is a pretty complex concept and isn't really necessary to bring up here

2)your falling back on what you said, im sure the other guys were referring to your even during prolonged fasting the body sets priorities type of posts.
