OPTIMAL KETONE AND BLOOD SUGAR LEVELS FOR KETOSIS
JULY 20, 2015 MARTY KENDALL
A low carb helps reduce blood sugars and insulin levels and helps improve common metabolic diseases (e.g. diabetes, heart disease, stroke, cancer, Parkinson’s and Alzheimer’s).
We become insulin resistant when our adipose tissue becomes full and can’t store any more energy. Excess energy is then stored in the liver, pancreas, heart, brain and other organs that are more insulin sensitive.
Endogenous ketosis occurs when we don’t eat, and we burn our own body fat (e.g. fasting). While insulin and blood sugar levels are low, we may have lower blood ketones flowing from our fat stores.
Exogenous ketosis occurs when we eat lots of and/or take exogenous ketones. Our blood ketones may be higher, but our insulin levels will also rise because we have an excess of energy coming from our diet.
Most of the good things associated with ketosis occur due to endogenous ketosis.
Most people following a ketogenic diet have lower blood ketone values than Phinney’s ‘optimal ketosis’ chart, especially once they become fat adapted and are not trying to drive high blood ketones through the consumption of excess energy from refined fat.
If your goal is blood sugar control, longevity or weight loss then endogenous ketosis with lower blood sugars and lower ketones is likely a better place to be than chasing higher blood ketones via lots of added dietary fat.
