Muscles require energy to just be present on your body. Even if you're not flexing them, they still consume calories, which your body considers a liability in a state of caloric deficit. Hence the "use it or lose it" rule

Because our endocrine systems were tuned over millions of years where people never had an excess amount of fat

But also, muscle catabolism is overestimated. Most people start to feel weaker when they try to cut, but this is largely a consequence of decreased endurance, not muscle loss

Protip: There's no reason to not use drugs on a cut.

If you don't lift and don't eat enough protein during your cut, yes, you will.

My dick is already average size.I can't afford to lose any centimetre

>>36450920
i do lift, but i don't think i get enough protein desu. fuck man, i hate being skinny fat (almost out but still there)

>Hurr durr starvation mode

Daily reminder a sedentary male loses only a pound of muscle on average in a year. You'll be fine not eating for a few months

>>36450934
Then start eating man.

>>36450934
why would you cut as skinny fat??

>>36450965
well, im not completely skinny fat. i do have muscle. im 5'11 182 lbs right now, probably sitting at 15-16% body fat. should i just bulk then?

>>36450939
that makes me feel better, i kind of just want to cut hard as fuck and just get it over with.

>>36450965
You know what skinny fat is? Its the numale body with a bulging ugly belly and skelly rest of the body. If youre actually skinnyfat you wouldnt cut, but you probably misunderstand the term

Yeah but they don't have that much muscle to begin with, so they're gonna lose less of it, just how when you're really fuckin fat you lose fat way easier than when you're only a little fat

>>36450922
pretty sure your dick stays the same size
your balls just shrink

The fatter you are, the harder you can cut without worrying about losing lean mass. As you become leaner and only have stubborn fat left, the body likes to hold on to that, and at the same time it will look for any chance to get rid of some of that expensive (in terms of energy usage) muscle it has to carry around all the time.
The leaner you get, the more anal you have to be about your training and diet if you want to keep as much muscle as possible. The fatter you are, the less it matters.

can confirm, started using SARMs and lifts shot up like crazy. am now researching roids and will likely make the jump soon.

you can cut 31.5 kcal per kg bodyfat without losing muscle.

that's why it's easier to keep muscle when you're cutting if you're fat, than it is if you're skinny.
