NS 115 Analysis of the article : “Comparison of the Atkins, Zone, Ornish and Learn diets for change in weight and related risks factors among overweight pre-menopausal women In the experiment conducted by Christopher et al. the main purpose is to compare the similarities and differences among the Atkins, Zone, Ornish and Learn diets, for changes in weight and related risks factors among overweight pre-menopausal women.
