Earlier quoted context omitted.
I think intermittent fasting is easier to implement for the average person. It's much easier to tell someone that they can eat as much as they want, but only between 6-8pm (one meal a day). It's difficult to tell someone you can eat 3 meals but no more than 1500 calories in total. Once I start eating, I don't want to stop (until I'm full). But the point at which I'm full is way beyond my calorie limit if I am eating…
Just anecdotal, but I did 12-8 fasting for a few months and it was not at all effective. I was starving half the day and didn't lose any weight at all. Mornings were tough and I was achy and cranky by 11am. 3 months in and my body never adjusted. I switched back to a normal meal schedule and felt better and didn't change weight up or down.
On the flip side, I know multiple people who have tried the same and have your exact experience. Oddly enough, three of them had tried keto and had great results where I personally didn't. I know there's no real correlation there, just thought it was interesting. Try keto maybe?
