So when I used this window mentally, I didn’t actually start eating till 12:30pm or later.
By the time I tested this earlier window, I’d already gotten used to waiting longer till breakfast, so I found it hard to stick with an earlier window, and my first meal naturally drifted later anyway.
Since this experience broke my previous eating routine, it made me think about when to eat and to pay more attention to how hungry I was, instead of just eating because it was the usual meal time.
Eating in an 8-hour window didn’t seem particularly beneficial if I just ate the same amount of food that I previously would.
