Short-term changes in lipoprotein subclasses and C-reactive protein levels of hypertriglyceridemic adults on low-carbohydrate and low-fat diets.
"Short-term changes in lipoprotein subclasses and C-reactive protein levels of hypertriglyceridemic adults on low-carbohydrate and low-fat diets. CK Stoernell, CC Tangney, SW Rockway. Nutrition Research. 2008 Jul;28(7):443-9. "
Aim: to test the efficacy of a low-fat (LF) diet vs a carbohydrate-restricted (LC) diet, in subjects with elevated TG levels (>1.69mmol/L to <6.78mmol/L), for lipid profile, weight loss, C-reactive protein and satiety
"LF diet E: restricted (104.6kJ/kg [~25kcal/kg] body weight Carb: 50-60%E Protein: 15%E Fat: <30%E Saturated and trans fat: <10%E Intake: NR"
"Primary: C-reactive protein, TG and other lipids Secondary: compliance, satiety"
"Weight loss improved on both diets, but BG NS. CRP was unchanged in both diets. Most lipid panel scores were NSS WG. However, the LC diet performed slightly better on some lipoprotein subfraction scores."
"CRP WG: N BG: N WG NSS both groups BG NSS"
"Determined that 80% of LC group and 60% of LF group were compliant. Satiety and hunger scores BG NSS different although overall satisfaction was slightly higher for LF diet (5.5 vs 4.9)."
"Favorable reductions in small LDL concentrations after 8 wks suggest that a moderately restricted carbohydrate diet (20%E as carb) can promote a less atherogenic lipid profile when compared to the low-fat diet."
