2. No carb diets provide an inefficient way to fuel the body
What about the argument that ketogenic (no carb) diets convert the body to burning fat primarily instead of glucose for fuel? Wouldn’t that preserve more muscle? While it is true that your body will burn ketones as energy when glucose is not available, it will still attempt to burn glucose through another source. If you are still consuming a large amount of protein that is required to build and maintain muscle mass, the body will still have plenty of amino acids to convert into glucose. Believe it or not a true ketogenic diet would require a lower protein dose, not something conducive to looking like a bodybuilder.
