Caloric restriction lowers endocannabinoid tonus and improves cardiac function in type 2 diabetes.


ABSTRACT: BACKGROUND/OBJECTIVES:Endocannabinoids (ECs) are associated with obesity and ectopic fat accumulation, both of which play a role in the development of cardiovascular disease (CVD) in type 2 diabetes (T2D). The effect of prolonged caloric restriction on ECs in relation to fat distribution and cardiac function is still unknown. Therefore, our aim was to investigate this relationship in obese T2D patients with coronary artery disease (CAD). SUBJECTS/METHODS:In a prospective intervention study, obese T2D patients with CAD (n?=?27) followed a 16 week very low calorie diet (VLCD; 450-1000?kcal/day). Cardiac function and fat accumulation were assessed with MRI and spectroscopy. Plasma levels of lipid species, including ECs, were measured using liquid chromatography-mass spectrometry. RESULTS:VLCD decreased plasma levels of virtually all measured lipid species of the class of N-acylethanolamines including the EC anandamide (AEA; -15%, p?=?0.016), without decreasing monoacylglycerols including the EC 2-arachidonoylglycerol (2-AG). Baseline plasma AEA levels strongly correlated with the volume of subcutaneous white adipose tissue (SAT; R2?=?0.44, p?
