The Japanese, and other Asians, also eat a lot of carbs and little meat. They don't have near the insulin
problems we do in the US. Even though, in China, the average caloric intake is sometimes *higher*.
My take is that the whole carb thing is a red herring. Type 2 diabetes is more subtle than that, and the
only single dietary component I can find that triggers it is dietary iron. This is confusing in the US because:
1. Our carbs mostly have iron added
2. A lot of the well water has iron added
3. We eat more red meat than most countries
So in the US, if you eat more carbs, you get more iron. But that is not true in
Japan, where the rice has no added iron. Nor in France, where they don't iron-fortify the
bread.
It's a complex issue that is beginning to get some research. See:
I tend to think that fasting helps insulin sensitivity partially because it gives the gut
time to deal with permeability and bacterial growth and iron storage issues ... i.e.
"housecleaning". This speaking as a person with lifelong gut issues, that got
fixed mostly via IF. I do know that my fasting blood glucose has gone from 95
to 83 or so, and my diet is hardly "low carb". Most of my dinners consist
of white rice, fish, eggs, and stir-fried vegies. (Which is not "low fat" either: my fish
tends to be fatty and I use coconut oil and bacon liberally when stir frying!).
Today we had: Rice and moo-goo-gai pan with chicken, butternut squash soup, followed
by sweet rice with coconut and banana.
BTW my cholesterol and triglycerides have normalized while doing this,
and my joints are doing well also. Besides Fast-5, I take steps to lower my
iron levels, which were rather high due to well water and probably family
genetics.
Because I am the main cook in the family, the rest of the family also
follows this eating pattern, and I have to say their weight and bloodwork is
all very good. The main things I watch for, for them, are gluten (wheat basically,
which messes up gut permeability) and iron (which like I said, was high in our
water, now fixed: but also it is added to many foods, check the labels). They have
totally free access to sugar (lots of candy! which they ignore) pop (which they ignore)
fruit (which they eat sometimes, mostly if it is at a meal), leftovers (popular!) and
eggs (eggs, pickled or over easy, are a popular snack).
They tend to eat a lot of vegies and "carbs", but not so much the "junk food"
kind of carbs, and it doesn't cause them to gain weight or have health issues.
This is very similar to what I see with Asians ... they eat a lot of carbs, but
don't get overweight from them. There are other issues at play here.

Barnaby - I checked those pages in Eat-Stop-Eat and yes, Brad does say that fasting reduces insulin.
But I note he also said:
"On average, the Cretes were healthier than North Americans, with less incidence of cardiovascular and heart disease. Researchers attributed this improved health to a high daily intake of whole grains, fruits, vegetables and olive oil."
"High daily intake" of carbs? And Brad calls that a "healthy diet".
So, yes, if that is your normal diet, I can see how fasting for 24 hours WILL greatly reduce your insulin levels.
But what if you are in a ketogenic state all the time, by consuming less than 20g carbs/day? How much lower can your insulin levels go? Why would it be important, at that point, for them to go lower?
Thanks if you're able to shed more light on this topic...
