1/ Thread — #EatingWindowExperiment initial thoughts...

(If you need a primer, see the experiment design here: cholesterolcode.com/eating-window-…)

All in all, this turned out pretty well. Yes, I had to amend in tighter fasting window timing after the first day....

2/ Going from evening to midday was a very meaningful change with regard to how challenging it would be.

(For details on that, see cholesterolcode.com/eating-window-…)

I normally don’t like fasting more than 14 hours. But this window of 10am-2pm (3 meals) was surprisingly easy.

3/ I think the key was to intentionally eat enough calories that would have normally been over the course of a day anyway. That said, I might have been able to further restrict how much I eat in the last meal (2pm).

4/ Thus, it’s easy to imagine a scenario where I’m tweaking back the total food in that bloc by small amounts until I ended up with a sweet spot, assuming no additional decline in my basal metabolic rate, sleep, etc.

5/ Speaking of sleep, it was pretty comparable between both phases. Perhaps coincidentally, I had more dream recall in the tighter fasting phase. However, last night included some textbook anxiety dreaming. Regardless, it’s too small a sample size to draw much conclusion.

6/ after the blood draw this morning, I’m actually going to add a bonus phase for one additional week and retest again. I’ll be eating a low carb-ish meal I was having during covid that I suspect was making me gain slightly more weight, but I might’ve been simply overeating.

7/ I’m going to match the calories consumed to this experiment and see if my fasting insulin next week will be noticeably higher. I hypothesize it will.

I’ll be weighing myself as well, but won’t put too much stock in marginal weight gain given likely water retention.

8/ But perhaps of even greater interest is getting all the wide spectrum labs for a tight comparison with this diet vs the baseline. I’ll do a write up on this “bonus phase” and the exact diet in the next day or two.
