Why do people who eat lots of sugar tend to have below-average levels of unmetabolized sugar in their blood, even though eating sugar increases the level of unmetabolized sugar in the blood?

The correct answer should help explain why people who eat lots of sugar have an unexpectedly low level of unmetabolized sugar in their blood. The correct answer might tell us that these people have a feature or engage in an activity that tends to decrease unmetabolized blood sugar.

We don’t know whether people who eat lots of sugar are likely to be overweight. In any case, even if they were, we would still expect sugar consumption to increase their unmetabolized blood sugar.

The specific food source that provides sugar has no clear impact. We have no reason to think eating sugar from fruit or vegetables wouldn’t be expected to increase unmetabolized blood sugar in the blood.

For people who eat lots of sugar, sugar in the blood could be metabolized at an unusually high rate. This could explain why people who eat lots of sugar have below-average unmetabolized sugar levels.

This makes the discrepancy more difficult to explain. Less of a sugar-metabolizing enzyme would lead to even higher amounts of unmetabolized sugar in the blood.

Even if the sugar is metabolized after entering the blood, we’re still left wondering why these people have below-average unmetabolized sugar levels in the blood.
