most of us now run mostly on sugar all the time. This is not how God designed our bodies to work best. In fact, if our forebearers had needed to follow this eating pattern to survive, we wouldn’t be here. The human race would have gone extinct long before we reached our present age of food abundance. Why? Because for most of human history, our ancestors did not have a constant supply of carby foods and refined sugars. They had no refrigeration, for one thing, and couldn’t get fruit when it was out of season.
