That’s funny.
I haven’t had carbs (except for the minuscule amount found in eggs) in years.
I’m healthier and have more energy than I can remember. I am burning fat for fuel now, not sugar. And I have none of the insulin issues that are rampant in our society.
One can make the argument that since we’ve moved to promoting more and more “starches”/carbs, our obesity problem has exploded.
Fats are metabolized to glycerol that is fed into the exact same metabolic cycle as sugar to derive energy.
One can make the argument that as Americans have increased caloric intake and decreased caloric expenditure they have grown more and more obese.
On a molecular basis there is no exemption that somehow excess calories, if they are from fat or protein, cannot be converted into lipids and stored as fat by the body.
Excess calories, from whatever source, will be stored as fat by the body.
