WTF are you babbling about? He's not going to lose muscle from running.
Uhh.. do you know what you're taking about? Do you think that all weight loss is fat?
Yes, yes I do.
No, you don't
🙂 He will indeed lose muscle. How much depends on his diet, his overall physiological condition and a bunch of other factors. For the most part, it's simply impossible to lose fat and not some muscle, and it's equally impossible to lose fat and gain muscle at the same time. Losing fat is catabolic; gaining muscle is anabolic. If you force yourself into too large a caloric deficit you will lose muscle mass.
His best bet is to better understand what his caloric needs are. Simply saying, "I'm going to run 3-5 miles a day!" doesn't help. If he works out too long, operates in too large a caloric deficit
and has a poor diet he'll lose a lot of weight, but a lot of that will be muscle.
