This study examined changes in body weight, body composition and blood cholesterol levels of eight subjects on a very low fat diet intervention, and compared those changes with a control group of 11 subjects. The treatment group reduced their dietary fat intake from 39.75 % of total calories to 17.42 %. At the end of the 12 week intervention the grouped data showed substantial decreases in total cholesterol and LDL Cholesterol and moderate decreases in HDL cholesterol, body composition and body weight for the treatment subjects and slight increases for the control subjects. When the data was analyzed using analysis of covariance (ANCOVA) with the pretest entered as the covariate, the variables that showed a significant decrease were HDL cholesterol, total cholesterol/HDL ratio, body composition and weight loss. The drop in total cholesterol and LDL cholesterol did not show significance. This study adds to the growing body of knowledge regarding the positive effects of adherence to a lowfat diet.
