A study has found that 30 minutes less sitting per day can significantly boost your metabolism and improve your long-term health. The researchers focused on metabolic flexibility, the ability of the body to seamlessly switch between burning fat and carbohydrates for fuel. They followed 64 adults with metabolic syndrome, a condition that increases the risk of heart disease and diabetes. Half of the participants were asked to reduce their sitting by about one hour per day, mostly by standing more or incorporating light movement. The less they sat, the more efficiently their bodies managed energy and the easier it became to burn fat. The study found that standing more often, engaging leg and core muscles, was enough to drive measurable metabolic improvements.
