"Two of the authors of The New Atkins for a New You explored what happens to saturated fat levels in subjects who were placed on the Atkins Diet(4). The Atkins subjects consumed three times the levels of saturated fat as did other subjects consuming a low-fat diet. Both diets contained the same number of calories, meaning that all the subjects were losing weight. After 12 weeks, the Atkins group subjects showed consistently greater reductions in the percentage of saturated fat in their blood. Yes, those who ate more saturated fat had less in their blood stream than those who ate less sat fat.
"The two researchers then did a second study, using weight-stable men who habitually consumed a typical American diet as subjects. The men followed a low-carb diet akin to the Atkins Lifetime Maintenance Phase, which contained more saturated fat than did their regular diet. All foods were prepared and provided to the subjects during each feeding period. Enough food was provided to maintain their weight. After six weeks on the diet, despite consuming more saturated fat, the men showed a significant reduction in their blood levels of saturated fat. They also improved their triglyceride and HDL cholesterol levels, LDL particle size, and insulin level. This study further supports the conclusion that a low carbohydrate intake stimulates the metabolism of saturated fat in the diet(5). "
