INS and type 1 diabetes mellitus: The psychopathology of DEB in T1DM patients was proposed by different disease models; for example, the modified dual pathway model [8] suggests that T1DM is associated with DEB via three mechanisms: (1) carbohydrate counting-imposed food preoccupation, (2) weight fluctuations associated with variable use of insulin and subsequent body dissatisfaction, and (3) blood glucose fluctuations associated with mismatched insulin doses, excessive caloric intake secondary to hypoglycaemia, and the resultant weight gain.
