"...a study that looked at 105 full-time office workers showed that those who sat longer were about three times as likely to have a waist circumference larger than 94cm (37 inches) for men or 80cm (31 inches) for women.
Waist circumference, as you probably know, is strongly associated with cardio-metabolic risk.
These same workers were also nine times more likely to have a BMI greater than 30, which in technical terms would make them obese.
Meanwhile, another study showed that each additional hour of sitting led to larger waist circumferences, as well as higher insulin and lower HDL cholesterol. Not good.
In fact, the evidence against prolonged sitting is so strong that one paper asks if chronic sitting, in itself, ought to be considered a “distinct coronary heart disease risk factor”.
