Thank you Ted for the full text.
I see that two of the contributors are doctors Phinney & Volek. (They are two of “the good guys” for sure)
LC was defined as 6% carbs by caloric value;
MC was defined as 32% carbs ditto; and
HC was defined as 57% carbs ditto.
Fat was adjusted proportionately:
so that LC was 74% fat by caloric value;
MC involved 48% fat ditto; and
HC involved 23% fat ditto.
I think we can be satisfied that they actually used a Low Carb diet in this experiment. Obviously the numbers of subject is on the small side, but this may lead to more trials with better funding.
