If the subjects are used to carb- and sugar-heavy diet, the hormonal spikes will be very stressful on the body.
They also mention fat-heavy foods, but I suspect they are referring to foods high on both fat+sugars, not a green salad with copious amounts of olive oil.
Anecdotal, but one of the things I noticed when I switched to keto for a while was a drastic change in my relationship to sugar. After cutting out sugar entirely, I noticed that water didn't taste bitter anymore, something I'd always attributed to the hard water supply. Coffee is also wildly different now, and I can drink teas without any sugar, which confuses folks when I eat out. (In my part of Texas, iced sweet tea is so popular it's basically the default beverage.)
It's so strange. My whole life I hadn't given sodas a second thought, but that reward signal is strong. I don't think I ever want to go back.
