Decided to compare the DEXA readings to my SCALE readings - same scale of 2lb/division but on opposite sides of the chart for lean and fat:

Given that I have some clothes on during DEXA and none on the SCALE, I expect a little difference and that the difference would be less in the summer than the winter.
Also, the time of day is a little different… also, hydration, food flux, etc…
It looks like the majority of the error is in the lean mass but as I’ve been trying to time the scan closer to my weigh in (weekends), the error has been reduced.
Why does this matter for this high protein experiment? well…
The large change in DEXA lean mass between the carnivore and high protein data points is the biggest concern right now.
The SCALE projects almost the same slope for lean mass loss (pink) between “the start of carnivore (cyc. fast datapoint) to end of carnivore” and “carnivore to high protein”, but DEXA doesn’t. In fact, that slope (dark red) goes from being slight to being much steeper. The fat results are pretty similar.
So - DEXA says that I’m losing lean mass faster on this high protein experiment. But that’s a function of one datapoint in mid-june… If that lean mass measurement was off (artificially high) for any reason, it would drive the wrong conclusions.
Here’s the scale data at higher resolution.
Basically, I start off well for either… but then I falter and the almonds corrupt me (and my data). I really need to push through this wall.
We go on vacation in 5 days… so I’m going to try to simplify. I can’t measure every meal constantly and weight myself on a smart scale or DEXA. This will be for a couple of weeks too, so it’s going to take a bite out of my ability to track anything.
So - I’m going with high protein carnivore and I’ll estimate the portions as best as I can. I’ll keep a log with images and hopefully that’ll help reconstruct afterwards.
