Whey protein (WP) has been reported to reduce body weight gain and improve glucose metabolism in obese individuals. This study aims to assess and compare the effects of WP and its hydrolysate-leucine (Leu) supplementation in non-obese, insulin-resistant (IR) rat models, particularly the effects on insulin sensitivity, lipid profile, and antioxidant activity. ⋯ Our findings demonstrate that the supplementation of WP and Leu may improve IR and antioxidant stress without resulting in changes in body weight and energy intake in non-obese IR rats.

The aim of this study was to explore the heterogeneous association of consumption of food away from home (FAFH) with individual body mass outcomes including body mass index and waist circumference over the entire conditional distribution of each outcome. ⋯ Further public health efforts are needed to improve the nutritional quality of affordable FAFH choices and nutrition education and to establish a healthy food consumption environment.

The aim of this study was to establish whether the long-term consumption of reused canola oil contributes to the development of dyslipidemia, obesity, and endothelial function. ⋯ High canola oil intake over 10 wk was associated with increased adipose tissue and early endothelial dysfunction probably induced by peroxinitrite formation. Such deleterious effects were significantly potentiated when the consumed oil had been used repeatedly for frying.

Rosiglitazone improves insulin sensitivity and promotes weight gain in patients with type 2 diabetes mellitus, which could be useful in wasting and cachexia. However, its effects on cardiac function are controversial. The aim of this study was to investigate the effects of rosiglitazone on body wasting, body composition, cardiac function, and survival in a rat model of cancer cachexia. ⋯ Rosiglitazone prevents weight loss and improves survival in a rat model of cancer cachexia. It exerts beneficial effects on cardiac function.
