It's more nuanced than that. Speaking as someone who has done the diet and had multiple people around me also have results with it when other diets haven't worked (as well).

The hormonal impact of what and when you eat tends to have a larger impact than what a pure "calories in, calories out" model would suggest.

I've taken blood tests before and after 6 months of intermittent fasting (with a similar diet) and saw massive improvement in blood work and hunger pangs.

YMMV but his ideas are worth exploring.

So is it expected that you do this intermittent fasting until you reverse T2 diabetes? If so - how long? Six months, 1 year, more or less? Or does this depend on individual - how long it takes her/him to reverse T2 diabetes? Or is this a lifestyle change that you incorporate until EOL?

This is quantifiable.

Ideally start when you’re only in the “pre-diabetic” range: fasting glucose above ~105ish, A1C > 5.7.

Those are the numbers you’re trying to lower. So how long you go with a dietary change depends on how well you’re able to manage this numbers down, and keep them down.

Surely some of this depends on how rigorously you can decrease your sugar intake, fasting or not, and/or restore better function of your systems (e.g. exercise, fasting).
