How do you feel not eating for a day? Just wonder if a lot of muscle will come off with the fat. No doubt that getting very lean by any method some muscle is lost.
No, you won't lose excess muscle from fasting for short periods like 24-36 hours.
Anytime you lose weight you lose both fat and muscle.
I've done fasts from for example 9PM Monday until breakfast on Wednesday morning but I don't like those long fasts.
16/8 wasn't bad because you are asleep for 8-10 hours of the fast.
There is no magic to fasting. It's just a way to schedule calorie intake. That's all it is.
If you are allowed to eat 2000 calories a day (24 period) you are still eating the 2000 in the 24 hour period. You are just scheduling the eating differently.
No magic effects as far as weight loss is concerned.
