Sorry
@lindisfel but i don't understand your question. My goal is to avoid producing the excess insulin in the first place, because of insulin resistance and unstable blood glucose, both of which make me feel rough.
My experiences of RH are that if (say) i started with a pre-meal reading of 5.5, and ate carbs, i would spike rapidly, then drop rapidly to significantly less than 5.5.
Lots of variables (as always!) speed and height of spike depending on g of carbs, fat content and fibre content of meal, etc. So predicting the peak of blood glucose and the timing of the insulin response would be an arcane art form.
The drop severity is usually proportional to size of carb portion. So keeping to very low carb prevents a hypo.
But if I do eat carbs, and know a hypo is likely, I can 'head it off at the pass' by eating something (preferably low carb, high fat with a few carbs in it) as I feel the blood glucose dropping out of the comfort zone.
Now I have the Freestyle Libre I can see this on the graph as a spike and steep drop which turns abruptly into a horizontal line as the snack blocks the hypo. Things are complicated by the fact that RHers often have a 'double hump' to their blood glucose curve, making it very difficult to know when insulin is at max output.
Without the snack, the drop would just keep plunging downwards to the 2s and 3s (mmol) until the stress hormones kicked off a liver dump.
