I'm no expert, but that sounds pretty crazy. From what I know, it takes at least 2 weeks (not days) to begin to lose muscle mass. So to formally answer your question, NO you cannot lose 30% muscle mass in 2 days!
Depends how much you weigh. Which hard work and dedication, it's possible.Only if you weight near 500 pounds, though.
Diet and exercise are the best way to go.
You cannot lose thirty pounds of body fat in one day by any natural means.
Doing this you will still lose muscle. The only reliable way to lose fat and keep muscle is exercising.
You cannot "lose" muscle unless you have muscle wasting, such as when very ill and bedridden. You can lose fat and shape / sculpt muscles.
Sure. Muscles that aren't used will shrink. An athlete that stops exercising will lose muscle

His father died, in his depression he spent two days in JD's bathtub. And he lost some muscle mass in his legs. lol
It is certainly possible to lose 10 pounds in 23 days. It is important, though, to distinguish losing weight from losing body fat. If you are overweight or obese, losing 10 pounds of body fat is a good idea; however, it's a bad idea to lose lean muscle mass. If you do not exercise and eat properly, about half the weight you lose will be lean muscle mass and that is a bad idea. Since lean muscle mass is very much more metabolically active than fat, you want to preserve or increase your lean muscle mass. Losing weight too quickly, and by that losing your muscle mass, will leave you worse off. You will quickly regain the weight and probably more than you lost.
