Lifestyle modification to decrease cardiovascular disease (CVD) risk has recently been reaffirmed by both the National Cholesterol Education Program and American Heart Association (AHA). Using a randomized crossover design, the Therapeutic Lifestyle Change (TLC)/Step 2 diet relative to a typical Western diet was assessed in 36 moderately hypercholesterolemic subjects in a clinical setting under isoweight conditions. Mean lipoprotein and apolipoprotein levels (fasting and non-fasting), fatty acid profiles, parameters of HDL metabolism, and glucose homeostasis were determined. Relative to the Western diet, the TLC/Step 2 diet resulted in 11% and 7% lower LDL cholesterol (LDL-C) and HDL cholesterol (HDL-C), respectively, with no significant change in TG levels or total cholesterol-HDL-C ratio. Similar responses were observed in the non-fasting state. Linoleic (18:2n-6c) and
The TLC/Step 2 diet resulted in a decrease in some CVD risk factors and no apparent adverse effects in others. Lichtenstein, A. H., L. M. Ausman, S. M. Jalbert, M. Vilella-Bach, M. Jauhiainen, S.

-linolenic (18:3n-3) acids increased at the expense of oleic acid (18:1n-9c) in the cholesteryl ester, TG, and phospholipid subfractions. The dietary changes had no significant effect on fractional esterification rate of HDL, phospholipid transfer protein (PLTP), or cholesterol ester transfer protein activities, or glucose and insulin levels. Female and male subjects responded similarly. ![]()
