Hi, I have been on LCHF for more than a year and really happy about it. I followed regularly the BG and ketones for the first 6 months but got tired to follow the low and not changing values. I have tried to find research studies about the metabolic control of BG and ketone bodies after long time in LCHF diet when everything has become stable. During the first weeks the ketone values were sometimes quite high and clearly over 1.5 mmol/l. After few months I have not seen any more values over 1.0 mmol/l. My assumption is that liver has "learned" to control better the ketone levels according to need. But is that the case? If so, what are the limits of ketone production in different situations? In addition, I would be interested in knowing if there are studies about the gluconeogenesis and insulin production in stabilized LCHF diet. Will any of the following occur: Pancreas becomes slower to react to fast and large BG rise when that has not happened for a year or two. How high can be BG level be just by gluconeogenesis? How fast that will stop if one eats sugar?
