Abstract

The prevalence of obesity and type 2 diabetes mellitus (T2DM) has risen to epidemic proportions. The pathophysiology of T2DM is complex and involves insulin resistance, pancreatic β-cell dysfunction and visceral adiposity. Although it has been known for quite some time that a disruption of biological rhythms (as happens with shift work) increases the risk of developing obesity, insulin resistance and T2DM, more recent genomic evidence has further spiked the interest for the involvement of circadian rhythms (and their disruption) in the development of diabetes. In this chapter, we will start with an overview of the way in which glucose metabolism and the basal rhythm in plasma glucose concentrations and insulin sensitivity are regulated, after which we will discuss how a disruption of daily rhythms or a disruption of clock elements, may contribute to the development of insulin resistance.
