Long-term effects of weight loss with a very low carbohydrate and low fat diet on vascular function in overweight and obese patients.
"Long-term effects of weight loss with a very low carbohydrate and low fat diet on vascular function in overweight and obese patients. TP Wycherley, GD Brinkworth, JB Keogh et al. Journal of Internal Medicine. 2010 May;267(5):452-61. Epub 2009 Oct 6. "
"Both diets SS improved FBG, HDL-C, TG, SBP, DBP with BG NSS. Total C, LDL-C, and FMD (-2.1%) worsened SS on LC diet. BG SS. PWV and other markers for endothelial function: most SS improved on both diets with BG NSS differences. However, ICAM-1 only SS improved on LC diet. BG SS. Both diets results in SS reductions in weight and BMI."
"Dietary records indicated dietary compliance was consistent with the prescribed dietary patterns."
"FMD WG: N BG: N Worsened (-2.1%) in LC diet but not LF diet PWV WG: Y BG: N improved SS with both diets WG p<0.01 BG NSS Endothelial function PAI-1, tPA, eSelectin, adiponectin WG: Y BG: N improved SS on both diets BG NSS VCAM-1 WG: N (both groups) BG: N BG NSS ICAM-1 WG: Y (improved only on LC diet) BG: Y "
" ... both LC and LF hypoenergetic diets achieved similar reductions in body weight and were associated with improvements in PWV and a number of endothelium- derived factors. However, the LC diet impaired FMD suggesting chronic consumption of a LC diet may have detrimental effects on endothelial function."
