"We think that diabetes represents a dysfunction of neural circuits within the brain. What FGF1 is doing is acting upon these circuits to ameliorate the dysfunction."

This is certainly a very interesting angle. Perhaps intermittent fasting/ketogenic diets have significant impact on FGF1 levels in the brain.
Probably not in the way you'd like.

Maybe that's why the Newcastle, very low calorie, and low fat diet seems to have a better result?
This presumes that we even understand what a "healthy" diet is! Low fat / high carb diets, as highlighted in recent studies and literature (as well as the media), also seem to lead to heart disease and obesity whereas high fat does not necessarily? So who to believe?
I'll believe what actually happened in the FGF1 studies, rather than arguing about the labels.
(I don't think anyone has mentioned heart disease or obesity, so that's not relevant to your original post)
@SunnyExpat - it states a high fat diet, but makes no mention of carbs. It would be interesting to know what the macros were that they were feeding the groups, not just ONE macro. That is unhelpful.
If the suggestion is that the brain may be responsible for some T2 then does this suggest stress as a precursor? I developed T2 at a highly stressful point in my life 2 years or so ago and have continued with significant stress since. With no familial background or predisposition and no obvious weight or health issues plus a background of heavy sport indulgence and decent diet, it has been a total surprise. A chronic back condition requiring 12 years of oxycontin use raises suspicions. Stress clearly affects cortisol and this affects glucose/insulin so has the brain compensated in sone form mistakenly and until stress can be diminished it could be a catch 22!??Would you think it would effect the FGF1 response?
Not sure, but it seems that if one was going to say high fat causes t2 because the mice ate high fat and they got fat and developed t2... One would have to indicate fairly what the rest of the macros were. A standard american diet leading to obecity and t2 is high in fat too, but also high in refined carbohydrates. Lchf diet, for example is high in fat (obviously), but takes out much of the carbohydrates... That would not be the same diet, would it? I don't know what the effect on the fgf1 response would be, but as scientists, they can't pick and choose what parts of a research project they want to disclose, not ethically anyhow. You could find three sets of lab rats, feed one a lchf diet, feed one a lclf diet, and feed one a SAD diet. Now, all is fine, but if you happen to mention that one of the groups also were given arsenic in their water, and that group died. Well, don't go blaming the diet. So if you say we gave them loads of fat (but "forget" to disclose the carb/protein levels) then it isn't the whole picture.Would you think it would effect the FGF1 response?

Not being adversarial, just pointing out that the link did not give full disclosure of all the elements in the "scientific" comparison.
We report that a single intracerebroventricular injection of FGF1 at a dose one-tenth of that needed for antidiabetic efficacy following peripheral injection induces sustained diabetes remission in both mouse and rat models of T2D. This antidiabetic effect is not secondary to weight loss, does not increase the risk of hypoglycemia, and involves a novel and incompletely understood mechanism for increasing glucose clearance from the bloodstream. We conclude that the brain has an inherent potential to induce diabetes remission and that brain FGF receptors are potential pharmacological targets for achieving this goal.
Logistic regression analyses demonstrated that serum FGF1 was significantly associated with type 2 diabetes (P<0.01). Circulating concentrations of FGF1 are significantly increased in T2DM patients. Our results suggest that FGF1 may play a role in the pathogenesis of T2DM.
There were multiple genes with increased expression that were enriched for RNA processing and developmental proteins. Growth factor genes-GHRH and FGF1-showed differential methylation and mRNA expression changes after resistance training.
Yes...lets leave the high fats discussion for other threads
From the original study...FGF1 in the brain seems to be the magical key...
This other study shows that we newly diagnose T2D should already have elevated level of FGF1 in serum, possibly compensatory as per elevated insulin ...how can we enable it to repair our neural circuits?

This study on resistance training also seems to provides some insights...on increasing FGF1...
