I know it's a big deal right now, but I don't know much about it.

I sort of stumbled into it by accident because I don't feel safe eating at work right now, so most days I don't have any food until I get home around 4:00 to 4:30 PM. I'm also usually wrapping up my evening and in bed by 9:00 PM, so I end up with a roughly five hour window in which to eat. Last weekend I tried to follow it even though I was home and found it surprisingly easy to just not eat until that time, even though it was safe for me to do so and food was available.

I was already calorie counting prior to this, but I noticed the shift to not eating at work accelerated my weight loss a little bit. It's also way easier to come in under my calorie count when I don't eat for most of the day.

Because it seems like this is working (though granted, I'm in the very early stages), and because I don't really have a choice in the matter given that I can't safely eat at work anyway, I'm interested in learning about the do's and don't's of intermittent fasting. As a beginner to this, what should I know? I am mostly interested in just making sure I'm not doing any damage to myself or creating any potential problems that I don't realize, so safety is my primary concern. Weight loss is a secondary focus, though less essential because I feel like I've got that down with calorie counting. Any insights or resources you know of would be appreciated.
