IntroductionSubstantial, sustained efforts in multiple domains are required to effectively manage type 2 diabetes. Management typically involves modification of diet and physical activity to increaseinsulin sensitivity and reduce blood glucose levels [1, 2]. Frequent blood glucose testing is also recommended, to allow immediate responses to glucose fluctuations [3]. Initiating andmaintaining such a complex and demanding regimen is heavily dependent on developing and sustaining motivation, which is the key to establishing goal-directed behaviours [4, 5]. While adjustments to health behaviours are not inherently motivating [6], autonomous self-motivation can play a crucial role in adherence to a dietary regimen in diabetes [7]. However, motivation is inconsistently defined, measured and targeted in individuals with type 2 diabetes.
