For the second time, Doug never said it was. He said a fat fast may be
enough to affect certain metabolic changes that would negate the need
for bariatric surgery.

He didn't say the POST-BARIATRIC DIET IS A FAT FAST.

The beginning point of the post-bariatric diet is on the order of 1000
calories so roughly similar to the original fat fast experiment in that
sense. It's closer to the 90% protein experimental group than to the
90% fat or 90% carb experimental groups. It does not match any of them.
It is similar in number of calories to all three groups.

The sole issue was Doug trying to attribute
the mysterious effects seen in these patients to a LC
diet. Which is wrong.

Doug, being of sound mind, wasn't attributing anything, he was
suggesting that there's nothing mysterious about it, that diet alone
can produce the same effects in most people, and without undergoing
dangerous surgery.

But I'll defer to Doug on that.

Feed a patient the post-bariatric diet without the surgery and see. I
suggest it is very likely the results will be close.

Speculation - The stomach produces ghrelin. The surgery reduces the
ghrelin produced by the stomach. Part of obesity is an imbalance in
hormones produced. Perhaps the post-surgery effects can't be reporduced
with diet alone. But I am unaware of a group fed the poost-surgery diet
as a control group.
