Cultish fervour??
Reducing carbs has been known as a treatment for diabetes since the late 1700s. It's only in the last 40-50 years that there's been a mistaken belief that we should cut out normal healthy fats which have been replaced with higher carb food instead. So reducing those unnecessary carbs again is plain common sense IMO.
I've always eaten normal full fat food as did my parents who lived to a ripe old age (mum was in her mid 90s.)
I certainly don't believe in needing to stuff my face with fats, but eating enough to provide major energy rquirements (instead relying solely on carbs) is actually
normal - the way we're designed to work and a much more efficient use of both dietary and stored "fuel".
Apart from cutting out all the high carb food - which I don't actually miss - the rest of my diet is, with some extra fat, very similar to what I've always eaten, and I've reduced and
kept my glucose levels for the most part to low pre-diabetic/high normal for just over 5 years now.
I eat LCHF because it both makes absolute sense to me
and it works. Simply put: my body can no longer handle carbs correctly so I've reduced them to the point where my ancient pancreas is able to cope again. (Same as with food related migraines, I learned to avoid those trigger foods...) My diet has also resolved other non diabetic issues, such as a lifetime's chronic migraines and more recently 5-6 nightmare years worth of living like a brain dead zombie pre diagnosis.. I no longer take any diabetic meds (metformin) , and I've been able reduce some non-diabetic ones too.
