Dieta di collegamento nella metabolica

mi permetto di scrivere, per i posteri che dovessero incappare in questo thread.
Non perchè io voglia avere ragione ma perchè mi preme fare buona informazione.

Il fulcro della discussione era:
"è possibile la chetosi anche in presenza di buone riserve di glicogeno epatico?"
la risposta è NO.

tratto da "the ketogenic diet" di Lyle Mc Donald (1998)

The major determinant of whether the liver will produce ketone bodies is the amount of liver glycogen present (8).
The primary role of liver glycogen is to maintain normal blood glucose
levels. When dietary carbohydrates are removed from the diet and blood glucose falls, glucagon signals the liver to break down its glycogen stores to glucose which is released into the bloodstream.

After approximately 12-16 hours, depending on activity, liver glycogen is almost completely depleted. At this time, ketogenesis increases rapidly. In fact, after liver glycogen is depleted, the availability of FFA will determine the rate of ketone production. (12)
