I have already posted a few non diabetic CGM/FGM response patterns to food and exercise and even made my 2014 complete 14 days run available on this blog. In this very quick post, I will simply share the result of a full “strict zero carb” day on a non diabetic (your servant, now almost 54yo). A few BGM test strips were spent to ensure the CGM/FGM was working perfectly. The minimum of 62 mg/dL probably wasn't reached and came in what definitely looks like a prolonged compression.
I felt a bit dizzy around 15:00. My urinary ketones were positive at 16:00
I will stubbornly avoid discussing my opinions on that type of diet, short term or long term, in adults or kids. A comprehensive review of its issues and merits can be found here (pdf) on the paleomom blog
