It's funny, because I bought that "breakfast is the most important meal" line. Even on a low-carb diet, I made special efforts to have breakfast everyday. I'd take smoothies or other portable food on my car commute or if I was home tried to eat within an hour of waking up otherwise I'd lose track of time and forget to eat that all-important meal. When I started to read about IF and TRE, I realized that my natural instinct was to eat my first meal somewhere between 10:30 and noon--a 14 to 16-hour fast from my last meal. How's that for intuitive eating?
