Yeah, I read through most of the paper, and by their description I can say i've been doing TRF (Time Restricted Fasting) for most of my adult life, and occasionally IF (Infrequent Fasting) i.e the odd day.

I never had time for breakfast, and when I rarely have lunch I usually don't much feel like dinner afterwards. I've never had weight problems (yes i'm >30) but I wonder how one can self determine any of the suggested benefits beyond that... I'm tempted to buy one of those keytone measurement thingies just to see if this is really the case for someone who has never done any different.

[edit]...Thinking back, I do a lot of climbing, and I am surprised some days when I perform really well in spite of skipping eating up until that point in the day - maybe it was actually always an advantage after all as this paper is suggesting. Curious to see if my sends correlate with high keytone levels now :P
