I have read that fasting can really improve one's metabolic health. I cannot remember but I think that there are fasters on our board. My metabolic issue is blood sugar that while not diabetic, is higher than normal, (A1C's from 5.2 to 5.5.) I would like to break below the 5 % level. I have a really strong dose of diabetic tilting genes. My Dad had diabetes but did manage to live almost 50 years with it, into his late 80s. My sister and all brothers have it, yet are doing well, I think mainly with low carb discipline that they started after they had been diagnosed.
I watched a Youtube video by an Aussie pathologist named Ken Sikaris M.D. I recommend this to anyone who has an interest in DM. He presented a lot of unexpected and non-intuitive findings that suggest for long term well being, it is really worth the effort to push those A1C readings down, even if they do not seem particularly bad. He thinks A1C is the gold standard diabetes test, as it essentially integrates blood sugar exposure over time by measuring glycosylation of the rbc (s), which measures average blood sugar over a period of 2-3 months.
Fasting would help me, but wow, fasting seems almost overwhelming. I am pretty sure I could walk 10 miles/day 6 days/week in the rain carrying a pack more comfortably than I could get by on one meal/day. Yet supposedly that one meal per day will do more for blood sugar than heavy exercise. My BMI is 22.5.
