In a way, it's about what you can stand (the most!) and what gives the best defatting the liver/blood glucose regulation results for you personally.
That's my own feeling about the difference between no-food fasting, or intermittent fasting, compared to VLCDs (whether you base it on Taylor or Mosley).
And the only way you can see how you feel and live the best, and what gives your blood glucose regulation system the best push for health - is by trying a bit of both of the methods out. Compare and contrast, and choose! Easier said than done, absolutely. But as someone who has experimented a lot with these regimens, this is the conclusion I came to for myself.
I agree that if treating your diabetes over a significant period of time with diet (and exercise if that is your bag too), you end up doing a mix and match of various treatment methods to find some sort of regimen, or intense treatment that suits you best.
Lucky people who can do any of these treatments and reverse their diabetes pretty pronto smart. Especially pre-diabetes. And find a maintenance way of eating that really works for them. And we see plenty of examples on this forum. But everyone with insulin resistance type two can get better than they were before by using these intense treatment methods using various ways of not eating. It might not be reversal/remission/cure etc, but it will be an improvement. Is my two cents worth.
