Given the following:
* Most people don’t exercise very much
* Exercise burns less calories than most people think
The problem for the overwhelming majority is “how do I dispose of excess sugars, simple or complex,” not “how do I replenish depleted liver glycogen?”
Umm, yeah. To my mind, the value of reducing carbs in your diet (as I do) is not for some magical thing it does to your metabolism or what it does to your insulin levels, it’s what it does to general energy balance (read: I think there’s a pony in there somewhere). This is also why I don’t see the usefulness of eating tons of non-nutritive fats either while I’ve got lots to spare!
As they say, your mileage may vary.
