This is a follow-up research study to determine if there are any differences in the
long-term maintenance of two diet groups, the Atkins’ diet (low-carbohydrate) or the LEARN
program (low-fat). The Atkins’ diet continues to get a significant amount of popular
attention and very little scientific evaluation. Due to the small amount of scientific data
to support a low-carbohydrate diet and given the wide spread use of this type of diet, it is
important to evaluate the long-term safety and effectiveness of the Atkins’ diet.

We will evaluate whether there are any differences between these two groups 3-years after
participation in the initial 1-year study period. We will specifically assess weight,
cholesterol levels, glucose and insulin levels, and eating habits and mood as we did
originally.

***PLEASE NOTE: Only those who participated in the original study of low carbohydrate and
low fat diets are eligable for enrollment in this follow-up study***
