Truthfully I thought that until I started having some weird symptoms. Further down the road and here is the rub.. 5 days a week I am a lean eater.. so much so that the A1C doesn’t pick up the aging shift of glucose impairment.
I have been testing A1C for decades, when it first came out it was FDA not cleared for diagnosing diabetes or impairment.
However, the lazy docs disregarded that. I had to fight for a real glucose tolerance test because my workday diet hides the truth about my glucose metabolism.
Unfortunately I am also hypothyroid and cannot store glycogen, so I am stuck.
A low carb diet will starve glycogen dependent tissue.
So calories in and out only works in good health. Your lack of care for there is pitiful. Maybe you should join the my way or else gender benders who are also uncaring.
All that is true. However it is inescapable that calories in vs calories out is subject to the laws of physics. You cannot create units of energy (calories) from nothing.
