Dear participant,
You are being asked to be a volunteer in a research study.

Purpose:
The purpose of this study is to understand how people use computer technology during juice fasts, cleanses or phases of ‘clean eating.’ We also want to know how your use of technology for diet has changed over time. Eventually, we want to design technology to better support clean eating. We expect to enroll 20 people in this study.

Exclusion/Inclusion Criteria:
Participants in this study must have at some point started a juice, smoothie, or other ‘clean eating’ diet. Participants must be 18 or older.

Procedures:
If you decide to be in this study, we will interview you. We will contact you to schedule an interview. The interview may take place on the Georgia Tech campus or at a place of your choosing. You may also choose to conduct the interview over the phone. The interview should last about 40 minutes. It will last no more than 60 minutes. With your permission, we will audio record the interview. Remember, you may stop at any time.

Risks or Discomforts:
The risks involved are no greater than those involved in daily activities such as talking about food and diet.

Benefits:
You are not likely to benefit from joining this study. We hope that what we learn will someday help others better manage their diets through technology.

Compensation to You:
There is no compensation for participation.

Confidentiality:
The following procedures will be followed to keep your personal information confidential in this study:
