Hi,
I’m 40, I’ve been on strict, clean keto for over 1.5y with time restricted eating (usually 2 meals within a 4-6h window). Sometimes I fast 1-2 days.The diet was easy for me from the start, no keto flu, started making ketones early. I wasn’t overweight, but still lost a few kilograms. I feel good, enjoy keto and how easy it makes my life. The reason I went on keto was that I had daily loss of energy in the afternoon (falling asleep sitting), this does not happen anymore.
However, I worry if I am really fat adapted. I’ve read that with time your body should get more efficient at using the ketones it produces and the blood ketone levels should naturally go down to sth like 0.5mmol/L, yet I am still at 2~3 mmol/L on a daily basis, with up to 7 mmol/L after exercise. My glucose is around 70-90 mg/dL daily, down to even < 50 mg/dL after exercise.
So I wonder - does anyone else experience this? Should I worry that my body doesn’t really use all the ketones it produces?
