Akk. She gets into this low fat diet that supposedly reversed diabetes--because the people could eat as much as 500 carbohydrates a day and still be off insulin. Denise Minger reported a similar thing in a recent Ancestral Health talk--people on the rice diet supposedly reversing their diabetes, and even being able to loosen up their diet with time--although during the question period, she admits that this basically amounts to adding a bit of lean protein to the diet. The rice diet was extremely low fat, allowing plain rice, fruit, and unlimited amounts of sugar.
This is a problem of definition of diet. Assuming going in that what's claimed is true. If a person can't eat carbohydrate without dysregulated fat and glucose metabolism--because dysregulation of glucose metabolism pretty much inevitably means dysregulation of fat metabolism--we call this carbohydrate intolerance. Obviously not eating carbs doesn't reverse this, it just avoids the carbohydrate. But it does address the fat intolerance very well, doesn't it? A high fat meal no longer results in an inappropriately sustained level of blood triglycerides, if a person goes on a low carb diet, in most cases.
Switch to the low fat, for people it works for. Maybe glucose tolerance goes way up. But these people had better never return to the SAD, high fat and high carb diet. Adding glucose to a low carb diet exposes the fact that low carb doesn't permanently cure a carbohydrate intolerance, I'll accept that.
It seems equally obvious that a diet almost devoid of fat doesn't cure a fat tolerance--because adding fat to a low fat diet also exposes the fact that low fat doesn't permanently cure a fat intolerance, it just sidesteps the issue, just as a low carb diet sidesteps the issue of glucose intolerance.
Looked at this way, it's a problem of metabolic flexibility, and it becomes reasonable that two radically differing dieting strategies could both be therapeutic. Calling one strategy a cure, the other not, involves ignoring a good part of the disease. This seems ludicrously obvious.
If we have a choice of glucose tolerance, or fat tolerance, which should we choose?
Hint; Denise's video includes a newspaper clip where the founder of the Rice Diet admits that he sometimes whipped his patients to encourage compliance.
