The basic science research has significantly increased our knowledge of this phenomenon, which has become a silent killer in our society. The main factors involved in insulin resistance are obesity (mainly abdominal), lack of physical activity, loss of muscle mass and secondary diminution in insulin action followed by diabetes mellitus. The changes in lifestyle and diet observed in many older subjects increases the risk of insulin resistance and diabetes. This paper will underline the main elements for primary and secondary prevention of insulin resistance in older adults.
