"Another 22% of the population is moderately inclined toward physical activity. Although not particularly athletic, they do spend their energy on moderately physical activity often of a social nature, like dancing or working on their feet. They need moderately-rich fuel. This group would do best with a diet of moderate carbs since their energies are inclined toward moderate physical activity."

That leaves a 1% margin of error, is all.

Also, this makes intuitive sense, but I'd also be interested to know where you did your research.
