Interrupting sitting with short episodes of walking appears to improve glucose metabolism in overweight or obese children without making them want to eat significantly more

In October 2018 researchers from the USA published the results of their study to assess whether interrupting time spent sitting with very short periods of walking improved glucose metabolism without affecting dietary intake in overweight or obese children. 35 children, aged 7-11 years, spent three hours sitting with no interruptions and on a separate occasion three hours sitting interrupted every 30 minutes with 3 minutes of moderate-intensity walking. Insulin, C-peptide, and glucose levels were assessed every 30 minutes during each session, and each session was followed by a buffet meal. Results showed that Interrupting the time spent sitting with short episodes of walking appeared to improve glucose metabolism without making the children want to eat significantly more.
