You might remember I did a 3.5 day fast about 18 months ago, and found I was struggling by the final morning. I did another at the start of Jan, and found it quite easy to do the 3.5 days this time. So now I know I can do that long, and give myself a good reset, whenever I feel I need it. I don't think I'd go longer than that though.
I came back onto foods one at a time, to see what I might be reacting to. And am now Paleo and close to, but not quite keto: P 30% F 45% C 25%, IFing for about 14 hours overnight, which seems to be my limit at the mo.
I do remember that. I've done a lot of fasting over the years, but it's been a lot harder to get into this time around. I'm blaming the advancing age... But I've had good results with the I.F. as far as my health is concerned, I'm hoping this will do even more. I'm planning on at least once a week for a little while.
I'm reading a lot of stuff about extended fasting, and with my health issues, I might go ahead and try it. I'm talking about 10-20 days. I've never done more than 5 so far.
Ah yes, the advancing age :-(
