1/ Some preliminary data from the #EatingWindowExperiment while we wait for the labs to come back.
These are the mean avgs for each period taken over the last 3 days of each phase (wake/7am/9am/2pm/7pm/10pm) compared.
Needless to say, this is some fascinating stuff...

2/ I was taking glucose and ketones (BHB) via @KetoMojo, lipids via CardioChek from @ptsdiagnostics
Where my test and meal times were the same, I'd take the blood test just before the meal.

3/ Again, I'm eating exactly the same thing in each phase, exercising the same, sleeping the same, etc -- the only difference is in the 10.5hr window my meals are 5 hours apart. In the 4.5hr window my meals are 2 hours apart.
(I added the 0.5 to reflect eating time of last meal)

4/ A number of interesting things jump out right away:
- Ketones climb in the 5hr gap for the 10.5, but climb higher for the 4.5 into the evening. This doesn't seem surprising at first given total fasted time.
However -- note they tighten up again into the morning...

5/ So while it might be tempting to assume a perpetual rise in ketones as the time elapsed since the last meal, this provide further data on the impact of sleep/morning cycle influence. Naturally, I'd love to be able to track various endocrine levels around the clock too.
6/ Super fascinating to watch total, HDL, and Non-HDL cholesterol levels, particularly when comparing the morning portion of wake/7am to 9am/later between each phase. Quite a difference to observe in the gap between the 4.5 and 10.5 windows earlier in the day.
7/ The triglycerides rising substantially post prandial was completely unsurprising (see my endless previous comments and blog posts on this topic, particularly for low carbers)
However, I was impressed to see how alike these trajectories were to each other later in the day.

8/ Note I do have a few "<50" readings that I converted to 45 in the TG (hence my calling it a "proxy") which was also used in applying the Friedewald calculation to LDL in this set of graphs as well.
9/ Lastly, while I will say it hasn't been the most pleasant exercise to extract that much blood from my fingers repeatedly each day (must fill a 40 uL capillary tube for CardioChek per test), I'm extremely thankful to have this data for comparison before the big labs come back.
