The close relationship between excess body weight, insulin resistance, and type 2 diabetes is well known (1). A decrease in weight improves insulin sensitivity, metabolic control, and the necessity for oral or insulin treatment (2). Dietary monitoring is a cornerstone of diabetes treatment, being essential to both improve current food intake and aid in the explanation of any disturbance in metabolic control. Dietary monitoring of food and energy intake (EI) therefore assumes that the dietary reports of diabetic patients are valid. Meanwhile, underreporting of food intake is widely acknowledged in obese individuals (3,4) yet is generally disregarded in the type 2 diabetic population, despite the fact that a significant percentage of this population is obese. The issue of EI underreporting and diabetes was first raised by Prentice et al. (5) and has since been discussed in only a few studies conducted in type 2 diabetic patients (6–8). The doubly labeled water (DLW) method is a state-of-the-art technique used to estimate total energy expenditure (TEE) (9). TEE refers to the energy requirement of an individual, which corresponds to EI under conditions of weight stability. The comparison of the ratio of EI …
