Do try it, but do you know how to do it right and safely? My knowledge is about 20 years old now, but at the time 2x a day enimas (ours were urine, but you can try salts as well, like epsom salt, not straight water) and strict restoration routine were the MUST or you were told you would poison yourself with the breaking down products. I dunno, fasting as in just not eating for days on end is a dangerous thing. People died from it....
It might not be that traumatic, but I would still caution and advise to have a plan B. Long fasts + stress are not the best combination. I always thought a Zen kinda mindset with a fair bit of leisure, contemplation and outdoor access at all times is almost a must for a longer fast.
Yes of course but you dont think people lost muscle mass as well during famines? You probably wont lose all that much in such a short time but you will lose some. Your body needs some amount of glocuse to run and your main reserves will run low in 8-12 hours, after 16-24 you body will start catabolizing muscle and organs for amino acids to turn them into glucose. It cannot do this with fat, it can however get good at using fat as the main source of fuel but its inevitable that you will lose some lean mass. Another thing to worry about is that after an extended fast, your body is primed to put back on allthe fat and then some. Remember, your body cant twll the difference between starvation and a voluntary fast. It will ensure it is ready incase it happens again. Look at anyones physique that does extended fasting. They will have next to nothing in the way of muscle mass and also very little fat but usually still enough to not have good definition.
If this is a one time thing to see what your limits are, then go for it. But dont have delusions that this is healthy.
Short term (IF'ing) can be used to shed fat while retaining lean mass and reduce the number of insulin spikes and gastric effect in a day.
Longer fasts are great for autophagy and for mental and spiritual purposes along with a generaly deeper detox.
The longer fast is not as lean mass sparing because that is not its function. You very well may end up with less muscle after the fast, but it should be of higher quality (body breaks down dysfunctional motor units for protein first hypothetically). So asking "how I do a long fast and not lose muscle...." is going to be a bit paradoxical. You will retain a good amount but by virtue of the fast you will need to loose a little bit.

*Nod*That is probably why various monks (meaning different religions) do this with no apparent issues.
The lack of sexual expression helps as well.
