I’ve been doing IF for a bit over a year, as well. Lots of info out there, so I understand someone new to it being confused.
I’d recommend continuing to read/watch information about IF as you go and as your schedule and interest permit. You will quickly to understand what is important to know about it, and what is relevant to your purposes.
For starters, I’d recommend aiming for a 16/8 six days a week. For most this amounts to skipping breakfast and distracting yourself from any midnight snacking, but your schedule might require some tweaking. It’s a generous window, however, and provides a few key benefits very quickly. One benefit being that you will personally experience how easy it is to do IF. Another benefit is that you will quickly experience and overcome what I call the “not really hungry hunger” that’s just your body craving carbs and/or expecting breakfast or a midnight snack out of habit rather than actual need.
Speaking of which, I definitely recommend cutting down on sugar/carbs, because that whole cycle is easy to kick as you start doing IF, and kicking it, in turn, makes it that much easier to stick with your planned eating regimen as the cravings for carbs/sugar will drastically reduce in a very short amount of time.
I also recommend counting calories (at least casually - it can be very difficult to keep an accurate, precise count, but a general ball-park is easy to keep an eye on). One of the stumbling blocks that people run into with starting IF is overdoing it on the amount of calories they consume in their eating window. Keeping track of calories is also a great way to encourage yourself to ensure that you are choosing nutrient rich foods over junk.
Lastly, get plenty of protein and fiber. Both are filling and provide long-term satiety.
If you follow these tips, after a few weeks you will be well-armed and confident to try out different types of IF that suit you, whether it’s a narrower window or even OMAD, or what have you.
And to paraphrase (slightly) Michael Pollan: Eat real food, not too much, mostly plants.
