Interesting observation.
Recently I got a call from someone eating 20 to 30 carbs a day split between two meals on the low carb ketogenic diet (LCKD) combined with intermittent fasting (IF). One day, her glucose level dropped to 68 mg/dL (3.8 mmol/L). She wasn't taking any medications or injecting insulin, and had no symptoms. We weren't sure if this was exciting or concerning. I loaned her Jason Fung's fasting book to sort it out.
I should add that previously, when she was bringing her glucose levels down from 400 mg/dL (22.2 mmol/L) levels, she was having "false hypo" symptoms when her glucose levels dropped to 130 mg/dL (7.2 mmol/L). Not fun.
