Closing three days in an hour or so, one more to go!
No particularly strong hunger pangs. Like you say, they come in waves, which you just ride through…
Got back some sleep deficit that had built up lately, and with that some additional and welcome mental clarity.
Last time, the fourth day of fasting was noticeably harder. wondering if this will be the case this time around.
Regarding frequency of longer fasts, I think @theanimal mentioned doing quarterly fasts, which sounds like a good frequency. Since fasting is supposed to bring an immunity boost, it could be done to welcome the season changes and weather the upsets they bring.
Your efforts in the health/diet/nutrition/exercise department and your sharing of stuff your read have been inspiring. I like how systematic you are in this. For instance, that video summary above is gold!
Calorie-counting and restriction does seem harder. Although of course having a good idea of foods nutritional profile, calories, glycemic helps make better choices. The section "Why “Eat Less, Move More” Fails: How Our Bodies Really Use Calories" from Jason Fung's "The Complete Guide To Fasting" was enlightening in that regard.
Since you have already taken strides in your eating habits and combine this with physical activity, I'd wager IF/OMAD and once a week or periodic longer fasts should be enough to keep that weight under check, with no counting needed! I've found OMAD a bit challenging to implement and re-implement, but once in place, it becomes a natural new default. But IF may be more sustainable to follow, especially when eating is a moment shared with family.
