I know from diets that low calorie intake does affect the mind, usually in a positive manner. That's not necessarily something I would call "hypoglycemia" though. I never checked, so far. Both glucose and insulin levels vary throughout the day, even in healthy people, so I don't see why blood sugar can't be "low", at least with respect to the individual's daily range.
