The findings are supported by the previous research of one of the authors. She studied 84 women whose job (cleaning hotel rooms) was very active. Half of the women were informed that what they did for work was very active, active enough to meet recommended exercise levels. The other half got a lecture about physical activity and exercise recommendations, but no one told them that they were sufficiently active. Interestingly, after only four weeks, not only did the informed women report that they were more active, they also had decreases in weight, blood pressure, body fat, waist-to-hip ratio, and body mass index.
