Long story is short I had some of these symptoms, fasting and keto made it way worse now even meat cause's a hypo. Would saying there is glucagon resistance due to long fasting and keto have any sense? And would eating carbs reverse this? An alternate could be cortisol resistance but I showed enough suppression to dexa. Any ideas? Its crippling my promising career because I can't think straight every 2/3h or so and I test between 4.2-4.6 when I feel "not bad". Also fasting insulin went down to 5 from 11. Any ideas? Last time I had a slice of bread (yesterday) I didn't suffer much even fruit.
