Yeah... sometimes weekly carb ups are suggested for maintaining 'metabolic flexibility.' Not so much. If you optimize for fat as fuel, you're not going to handle glucose as well. If anything it's just avoiding proper adaptation.

It would be interesting to look at the effects of every other day fasting (on a moderate or high carb diet) on this marker. I think that's a more appropriate model for metabolic flexibility, with the every other day preponderance of glucose versus fat.

Something else I'd like to see studied is the effect of glucose sipping. That same amount of glucose, sipped through the course of the day, instead of all at once, should cause less of an increase in insulin, less of a switch to glucose as fuel, more of the glucose being used for repletion of glycogen, if it works the same for low carbers as it does in the David Jenkins glucose sipping versus bolus studies.. Which is a main goal for many people who do a carb up on the weekends in the fitness community.
