Effects of weight loss from a very-low-carbohydrate diet on endothelial function and markers of cardiovascular disease risk in subjects with abdominal obesity.
Effects of weight loss from a very-low-carbohydrate diet on endothelial function and markers of cardiovascular disease risk in subjects with abdominal obesity. JB Keogh, GD Brinkworth, M Noakes et al. American Journal of Clinical Nutrition. 2008 Mar;87(3):567-76.
"The effects of a very-low-carbohydrate, high saturated-fat weight-loss diet on brachial artery flow-mediated dilatation (FMD) and markers of endothelial function are unknown. Aim: to compare the effects of two isocaloric diets - very-low-carbohydratte diet (VLCHF) vs high-carbohydrate, low-saturated-fat (HCLF) diet on markers of endothelial function and CVD risk"
"FMD was unchanged across groups and was BG NSS. CRP, total C and LDL-C improved more with HCLF diet. HDL-C and TG improved more with LCHF diet. SBP, DBP, FBG, fasting insulin, apolipoprotein all SS across time but BG NSS Adhesion molecules improved SS across time but BG NSS"
"Adiponectin WG: NR BG: N BG NSS "
"CRP WG: NR BG: N HCLF SS diet favored p<0.05"
"FMD Adhesion molecules Apolipoprotein WG: NR BG: N BG NSS "
"A LCHF does not impair FMD. We observed beneficial effects of both diets on most of the CVD risk factors measured."
