Abstract

BackgroundLow carbohydrate diets LCDs have been demonstrated to be effective tools for promoting weight loss and an improved plasma lipid profile. Such diets are often associated with increased meat consumption, either poultry, fish, and shellfish PFS, which are generally high in polyunsaturated fat PUFA or red meats RM, generally high in saturated fat SFA. The fatty acid profile and content of a diet may influence the plasma lipid profile of humans. This study examined whether the type of meat consumed could influence the outcome of an LCD.

MethodsModerately obese subjects consumed two different LCDs as part of a weight loss regimen: 1 a diet high in foods of mammalian origin RM intended to contain more SFA, or 2 a diet high in PFS intended to contain more PUFA. Diet dependent changes in body weight, nutritional intake, and plasma lipids were evaluated during a 28 day study period.

ResultsBoth diets were associated with significant weight loss after 28 days -5.26 ± 0.84 kg and -5.74 ± 0.63 kg for RM and PFS groups, respectively. The PFS diet was associated with a significantly higher intake of PUFA and cholesterol. Despite high cholesterol and fat intakes, neither diet was associated with significant changes in plasma cholesterol or the plasma lipoprotein cholesterol profile. While plasma triglycerides were reduced in both groups, the effect was only statistically significant for the PFS diet.
