Alright, and pair Fung's clinical experiences with Westman's, Unwin's, and Hallberg's Virta Health studies, and the positive influences become wider. Unfortunately, the idea of fasting becomes the lightning rod in this case, as it's unconventional and very hard for people to understand the idea of not eating to improve health. Some who have not read Fung's fasting policies and protocol will conclude that this is irresponsible and dangerous. What fasting is achieving for Fung's patients is equivalent to the dietary changes of eliminating carbs in the patients of Westman, Unwin, and Virta Health. Time restricted feeding (TRF) is a part of all clinical practices mentioned, so it also identifies a need to define fasting and IF. If it's a short duration fast, it can be termed TRF just as easily.

The other thing is that the observation by Gabbay:

is the reverse of the sequence in which I now understand this dynamic: People who start to have better blood sugar control can start to lose weight. This idea that losing weight as a singular activity and root cause is naive (triggers the worn-out recommendation to eat less, move more) and is a result of dietary changes that initially get blood sugar levels under control. As the mainstream "experts" get involved, we'll start to see the whole explanation of how carb restriction and IF/TRF works be repeated. Metabolic responses have been very well explained in books by Fung and Westman. There's a lot of catching up to do here for the "experts."
