How to know if weight loss is due to fat loss or muscle loss?
you don't Now go do RFL
>>77217548If I'm losing muscle can visibly see my muscle mass reducing and my lifts go down all else being equal.
>>77217548The only way your body consumes muscle before fat or glucose is through rhabdo aka overworking yourself. What you're thinking of is water weight, actual muscle fiber is the last thing your body breaks down alongside bone when starving
Get a BIA scale and weight yourself every morning post-pee. While day-to-day readings are subject to noise (pizza night = 2 kg of next-day "lean mass" that takes 3-4 days to normalize), they're directionally accurate - more so if your diet is reasonably consistent.
>>77217578BIA scales are inaccurate
>>77219351Depends, had a dexa scan and my muscle mass was 0.1kg off with withings.

>>77217548>muscle lossyour lifts go down>fat lossyour circumference goes downyou can check with a tape measure, or simply your clothes. if your clothes feel a bit loose, you lost a bit of fat. if you're low body fat already, you can measure with abs definition
>>77217578bia are dogshit>>77219367dexa are easily manipulatable through water intake>>77217561incorrect, when protein intake is insufficient for organ function muscle will be catabolized
>>77220485That's called starvation dipshit. I already mentioned that and your body will be gnawing other ressources way before getting to muscle fiber
>>77220498no, muscle will be catabolized even without starvingthere is also the tension requirement as without training muscle size will also go down, surplus, deficit or maintenance
>>77219351>>77220485My Tanita RD-545 is surprisingly consistent assuming my diet doesn't swing too much. Five days back to back:42.34 kg43.0 kg (pooplogged)42.2 kg42.28 kg42.26 kg
>>77219351>>77220485Thats why the anon said directionally accurate. Even if the absolute measurement is incorrect, if it is going down over weeks its probably actually going down. If its going up over weeks its probably actually going up.
>>77220546>if it is going down over weeks its probably actually going downbut the problem is that it could (and does) go down hour to houryou will never ever be able to replicate the same water and food consumption as well as hydration across the three main electrolytes and potential extra water weight from training every single week or day you weigh yourselfit's just shit at measuring what it's trying to measure because it does it through electrical impedance which not only doesn't give you a good bf% reading but it's also highly susceptible to water and mineral changes in the body and you could get wildly different measurments in one day
>>77217548if you are fasting then its about 95% fat loss compared to muscle. if you are doing a low calorie diet where you eat -500 calories under "maintenance" then its about 50% fat to muscle loss.
>>77217548Are you losing strength? Yes? You're losing muscle, if not then you're not
>>77217548The mirror.Only midwits struggle with basic questions like this. They think they can into nuance, but really, they can not.
>>77220756I lost 20kg and I look the same, musclewise and fatwise
>>77217548Simple: If you look good it's fat loss, if you look skinnyfat it's muscle loss.That's how the ancients like Arnold and Vince did it.
>>77220612>if you are fasting then its about 95% fat loss compared to muscle.Imagine taking /fit/ memes seriously.
>>77221598Nope, you just have body dysmorphia.
>>77221626I don't think I'm a girl.
>>77221626Three days of keto takes my visual guesstimate from 25% hamplanet with its own gravitational pull to 10% lean mean DYEL with visible striations
>>77220612Its true. Last cut i lost all my fat and muscle. Now im back to square one all over again.
>>77217548In my experience as long as you don't go stupidly hard on the deficit and still do your normal routine, your lean body mass should remain steady the entire cut. I lost 2lbs on average a week for 5 months straight, the most per week was never more than 3-3.5lbs a couple times, and I was not good about protein intake at all. I tracked my bf% with navy method and while not perfect it never deviated. My big compound lifts would remain steady or go down maybe 5lbs a month, but I was occasionally able to increase my accessory lifts. I did omad - a large meal with about a 1k deficit on my 4 lifting days, a small meal like 400 calories on 2 of my rest days, and the last day was a large meal where I went out with my friends or family.
