Diabetes is a major public health problem and is emerging as a pandemic. The fundamental cause of obesity and overweight is an energy imbalance between calories consumed and calories burned up. Physical activity is one of the mainstay clinical interventions for preventing metabolic diseases, and dietary habits are the primary factor for the rapidly rising incidence of DM. Reducing weight and maintaining a healthy weight, reducing energy intake, and food intake high in vegetables, fruit, whole grains, legumes, nuts, and dairy products are core parts of management. We performed a narrative literature review, manual-search of reference lists of included articles, and relevant reviews. The main purpose of this review was to discuss the role of psychosocial factors and diet in the control of type II Diabetes.
