Colorectal cancer (CRC) is the second most common cause of cancer-related death in the Western world and its prevalence is increasing. Potential causes of this increase are changes in diet and the increases in obesity seen. This paper looks at the literature surrounding diet and obesity and the links to this increase in CRC. Heralded as a weight loss miracle we investigate whether the literature suggests the Atkins diet may actually do more harm than good by acting to increase an individual's risk of CRC. Obesity has been demonstrated to be a major factor in the increase in CRC although links to changes in diet are more tenuous. Published studies on diet suggest the Atkins diet may help reduce rather than increase the risk of CRC.
