Prescription of energy-restricted diets with higher and lower pork protein content achieves weight loss and improved glycaemic control in adults with type 2 diabetes

摘要

Energy-restricted, high-protein diets have shown to be effective for enhancing weight loss and improving glycaemic control in type 2 diabetes (T2DM) (Dong etal. 2013). Regular pork consumption has also been shown to improve weight loss and body composition both without energy-restriction (Murphy et al. 2012) and during energy restriction (Wycherley et al. 2010), but there is little data available on whether benefits are maintained during weight maintenance following initial weight loss. The aim of this study was to compare the effects of a higher pork protein content (HPP) and a lower pork protein (LPP) diet on weight loss and glycaemic control (measured by glycosylated haemoglobin [HbAlc %]) in overweight and obese adults with T2DM during weight loss and subsequent weight maintenance. It was hypothesised that an energy-restricted HPP diet would result in greater reductions in weight and Hb A1 c than the LPP diet during weight loss, and these improvements would be sustained during subsequent weight maintenance.
