I did three days on green tea and coconut oil, but it was to shut down a serious autoimmune flare. Which it did in spectacular fashion. But I was a medical case. It's certainly not something that should be routine. i shrink my eating window since if I'm not hungry
enough as dinnertime approaches, I'll skip dinner, since lunch is usually my big meal.
It took 20 years, but low carb guided me to a my optimum diet, anyway! Because I got so sick my tolerance for ANYTHING fell through the floor, and I could only eat what my body really&truly agreed with.
I seem to not need the OMAD of one pound of hamburger I used to eat. If I was hungry I had a second, smaller, meal of the same thing. Since I don't really eat much plants, it supports my theory that my body can't get nutrition from plants. I have some fruit and veg that gets along with me, and if I want them I have them. But I can also sense my limits with them.
I think this shows that Intuitive Eating does work.
If, as in the original Davis Experiment, the only offerings are actually nutritious for people in general.
I remember her use of cod liver oil which had demonstrable healing effects for rickets. The boy most affected CRAVED it. (Have you ever had cod liver oil? This is not the usual, I can tell ya.) As the child grew strong, they started taking less, then stopped.
Perhaps these kinds of actions have a beneficial side to them. Actual body wisdom can exist or how did we get here?
But it only works when the food zone isn't flooded with stuff
designed to hijack that vital system.
