In diabetes, people make fructose because it's made from high glucose. But fruit dose drops the ATP level and that activates the switch. And if the ATP level goes to 80%, the switch has turned on a little bit. If it goes to 60%. So it's like a dimmer switch. It's not all or none. You can activate it like mildly and just recurantly or you can activate it big time for like one meal and then it will recover.
