Uhh Mike?
Not really. It actually preserves muscle tissue.
Also, according to Martin Berkhan,
Intermittent Fasting For Weight Loss Preserves Muscle Mass? | Intermittent fasting diet for fat loss, muscle gain and health
"
Right off the bat, let me note that the title and abstract does not mention intermittent "fasting" anywhere. Instead, the author is using intermittent "calorie restriction" (CR) as a catch-all term for various intermittent fasting regimens. This includes intermittent fasting (IF) and alternate-day fasting (ADF). Below I've listed the studies for intermittent CR included in the review:

Of particular interest is this one:
Effect of intermittent fasting and refeeding on insulin action in healthy men
(But to jump to the results, The body weight was maintained stable throughout the experiment (86.4 ± 2.3 kg, 0.8 ± 0.1% coefficient of variation) and percent body fat was also
unchanged before compared with after the fasting intervention (Table 1).
The level of habitual daily physical activity did not decrease during fasting days. Thus the average heart rate during daytime was not different during fasting (79 ± 3 min???1) compared with nonfasting days (80 ± 3 min???1).
Whole Body Glucose Metabolism
Plasma glucose concentration during both clamps was kept constant (Fig. 2), with a coefficient of variance of 4.4% ± 1.3% mmol/l during the last hour of the clamps.

Kindly apologize to everyone for making a complete asshole of yourself.
