Unfortunately I'm not techno-hip enough to post links, but if you google on RC Turner and metformin and monotherapy, you will find a couple of studies which show what happens when people with diabetes get the low-fat, high carbo diet, either alone or with sulfonylureas or metformin or insulin. Six to nine years later, their beta cells are all burned out, they are insulin dependent. This is what they've got to offer us, if we don't know about Bernstein.For me the most tragic/ludicrous statement was "since a low-fat, high carbohydrate diet is known to decrease insulin resistance..." So they did this study and never tried the obvious comparison, of people normalizing their sugars via Bernstein. And it never dawned on them that their own results should have made them question their initial premise about diet. Sheesh. I quote from somebody on a committee I once served on - "hey, we've all got Phd's but we're not Stupid..." not always true, I guess.
