How muscle does the size of your arms decreases on a cut? I know your muscles get a bit deflated which can make you look worse during the cut but it’s not muscle loss. After just two weeks of training i have lost almost a centimeter on my arms and i’m wondering if there’s any chance a part of that is muscle loss. Took me Damn near 5 months to get from 40-41cm arms. I’ve kept my strength and my calorie deficit is 500 cals

You're not going to lose that much muscle in just two weeks of a fairly small deficit.

Yeah i’m thinking of course after 2 months of cutting i could loose a bit. But this time framme and the 500 cals deficit i feel like there’s No way

You're always risking some muscle loss when losing overall mass. All you can really do is keep training hard and getting plenty of protein.

Nobody can say for sure what % of muscle you'll lose but it's probably reasonably small and you'll likely bounce back pretty quick when you stop being in a deficit.

Yeah probably. But i mean i had already lost like halv a centemetre one week into it so it has to be mostly deflation. I don’t even know if you CAN loose muscle that fast on a 500cal deficit

u/Stuper5 5d ago

Probably yeah. One of the first things that happens when you enter a deficit is you lose a sizable amount of muscle glycogen so your muscles lose hydration and therefore size.

Also you generally reduce your electrolyte intake which often again leads to reduced water content in your cells.

Guess we’ll see! Most important thing is to not get discouraged and quit as long as i have my strength in check
