Uh, there's likely more than a few confounders here, which are, at a minimum, undocumented in the report. Intuitively, one would expect lower caloric consumption with altered eating habits, which would lead to decreased fat and decreased intra-abdominal pressure. There's also no test of LES function prior to initiation of the experiment, so no delta was actually measured.

There's also a bit of misunderstanding, I suspect, in the pathology report: 0.2 x 0.5 x 0.3 cm is a perfectly reasonable size for an esophageal biopsy, and it was almost certainly measured with a ruler like (1) or (2).

I've passed this to a GI friend to get their thoughts, but suffice to say, more study is required before making this any sort of recommendation.
