If it were as unhealthy as eating donuts (which you would need to prove), it would most likely be unhealthy by a different mechanism. So it would make sense to distinguish this if you want to find out what causes illnesses.

I also don't understand what you mean by "low quality muscle mass".

Muscle with a low weight to power ratio, and/or with an unfavorable type I to type IIa/b ratio. E.g. you can quickly bulk up by lifting 3 x 3 at a high weight (or whatever Starting Strength recommends), but you're going to develop much lower quality muscle than if you just do 6 x 10 or whatever in terms of power. And similarly if you're not doing cardio in at least 90 minute increments then on a regular basis then your type II muscles aren't going to be able to properly utilize fat, because they'll never get past the point of just relying on stored glycogen or whatever.
