The prevalence of diabetes increased rapidly by the influence of socioeconomic interactions. The thrifty hypothesis postulates that certain genes that are involved in positive selection promote efficient fat deposition and storage. This is beneficial for the survival of mankind in adverse conditions. However, in this modern society, these genes have become disadvantageous as people are significantly less likely to experience famines and nutrition shortages. The socioeconomic development that has occurred during the 20th century induced abundance of food supplies in almost all regions of the world. This has led to a rapid rise in the prevalence of obesity, and type 2 diabetes as a consequence. Boom of diabetic pandemic in newly developed countries compare with others those who developed gradually can be explain by thrifty hypothesis, as a result of the difference in the exposure to environmental factors and famine by the ancestors leads.

Although modifiable lifestyle practices now account for some 80% of premature mortality, medicine remains loathe to embrace lifestyle interventions as medicine Here, we argue that a 21st century golden age of medicine can be realized; the path to this era requires a transformation of medical school recruitment and training in ways that prioritize a broad view of lifestyle medicine. Moving beyond the basic principles of modifiable lifestyle practices as therapeutic interventions, each person/community should be viewed as a biological manifestation of accumulated experiences (and choices) made within the dynamic social, political, economic and cultural ecosystems that comprise their total life history. This requires an understanding that powerful forces operate within these ecosystems; marketing and neoliberal forces push an exclusive 'personal responsibility' view of health - blaming the individual, and deflecting from the large-scale influences that maintain health inequalities and threaten planetary health. The latter term denotes the interconnections between the sustainable vitality of person and place at all scales.
