I think you hit the nail here. For the last half a decade I've tried most things in both nutrition and training. While I'm back to a moderate regiment now, both diet and training, not abstaining from anything I think the key takeaway is not of one diet to rule them all, but merely what insights each brings. From doing LCHF I realized how hunger is altered by carbs. From doing IF I realized how hunger is altered by ghrelin, and how it's very much trainable (in the span of about two weeks). Also how "real" hunger feels versus "fake" hunger, and that the feeling of hunger is completely harmless and can really sharpen your focus. How neither is particularily easy on your social life. Etc, etc. Even if I'm back to a "regular" diet now, I have a much better understanding of the things I eat, and can make more informed decisions, both on content, portion size, and meal times. Everyone should try everything (if time permits). Never be afraid of exploring outside your comfort zone.
