Walking is one of the easiest and enjoyable ways to stay fit and healthy, especially by older adults. Walking is a form of low-impact aerobic activity that burns calories and carries a very low injury risk. A study published in the Journal of Clinical Lipidology showed that people who did not have Diabetes were benefited when they took a two-minute brisk walk every half hour over seven hours. There was a reduction in the build-up of triglycerides by 7 per cent compared with sitting all day. Additionally, if these participants added a 30-minute walk at day's end then that build-up reduced by 11 per cent. This combination also caused a decrease in the need for the production of insulin, after eating, by an average of 23 per cent which could indicate improved insulin sensitivity; i.e.- that insulin now was able to work better.
