In 32 women of normal body weight who volunteered to participate in the study, the effect of rapid weight reduction by a low-calorie liquid diet on serum lipids and lecithin:cholesterol acyltransferase (LCAT) enzyme activity was studied. Women were on this 400 kJ/day diet for 7 days and fasting blood samples were drawn before and immediately after the diet. Serum cholesterol decreased from 5.7 +/- 1.0 to 5.2 +/- 1.1 mmol/l and high density lipoprotein cholesterol from 1.77 +/- 0.43 to 1.50 +/- 0.35 mmol/l. The serum LCAT activity decreased significantly during the weight reduction period. When serum LCAT activity was correlated to lipid parameters, a positive correlation was found with total cholesterol and triglyceride concentrations before weight reduction and also between changes in LCAT activity and total cholesterol concentration. The data suggest that serum LCAT activity might have a prominent role in the regulation of serum lipid levels.
