Link between self-control and blood sugar levels

There was an interesting blog post on the New York Times health blog yesterday. The post looked at a study that said “restoring glucose levels appears to replenish self-control. Study subjects who drank sugar-sweetened lemonade, which raises glucose levels quickly, performed better on self-control tests than those who drank artificially-sweetened beverages, which have no effect on glucose. The findings make sense because it’s long been known that glucose fuels many brain functions.”

The study wasn’t looking at people with diabetes, but I thought it fit well with how hard it is to treat lows. When you’re low, you want to eat everything in sight, even though you know you shouldn’t. It’s a very hard-to-control impulse.
