July 2 marked 2 years straight only eating from 6pm-10pm with bullet-proof coffee sometimes during the day. I grew up always needing food and I can attest that my body adapted to eating this way and totally changed when I started eating this way in the sense of strength and lean muscle. Generally I eat pretty clean, lots vegetables meat beans and lentils, with a cheat day once per week, but always within my eating window.
I try to drink a lot of water during the day too. I am conscious that the water is reverse osmosis and then I'll add a pinch of celtic sea salt, some apple cider vinegar, and lemon. I also use active h2 tablets which I highly recommend.
Have you had the same work hours for 2 years straight? That seems somewhat uncommon, unless you've worked at the same place in the same position for that long.
My current schedule, I would be asleep for most of your eating window. In the past 6 years, my working schedule has rotated around the entire 24 hour clock - early morning shifts, midday shifts, swing shift, early overnight shift, late overnight shift. My eating rotates around with my work shift, eating a small meal before work, a small one during (whenever during the day or night the shift is, there's a "lunch" break almost in the exact center) and a large meal after work.
