I’ve been doing this for quite a while. I don’t just skip breakfast; I don’t eat anything until late afternoon. But I don’t see the relevance of this study to me, even if valid, because I don’t do it to lose weight.
If I’m losing muscle (I’m not; I never had that much to begin with), it’s because I don’t work out as I should. If I did, I’d have to increase my food uptake (and I’d gain weight, but it would be in muscle). What the eating schedule for that would have to be, I don’t know. I suspect it would just mean that I’d eat more in the evening.
