You've started losing weight, good job! 
I do IF 16 hours overnight, sounds like you're talking about the 24 hour version which I haven't tried and don't plan to.
From my own experience I don't believe the stuff he is saying in the article as it's working great for me, and I haven't lost muscle either. After 6 or so months i'm still losing fat and putting on some muscle.
I'm no expert and it's not like i've been doing it for years, but I value my own experience much more than these articles criticizing it.
Though maybe it would be a better idea to just work on getting your eating healthy before you try intermittent fasting. If I tried it when I first started I probably would have had issues, I just started it like a year in when I had everything else going well.
