Purpose: This study aims to take the procedural and research-based lessons learned from a
pilot weight loss intervention (IRB # 13-02563-XP), conducted by The University of Tennessee
Health Science Center in 2013, and apply them to the current study of 204 active duty
military personnel. The pilot study translated and tailored the Look Ahead weight loss
intervention to an overweight/obese active duty U.S. Air Force population, while
accommodating the lifestyle and environment that is unique to military members and evaluate
materials and procedures used.
Rationale: Being overweight is now by far the leading medical reason for rejection in the
military. Unfortunately, the impact of weight problems on the military does not stop with
those turned away from military service. From 1998 to 2008, the Armed Forces Health
Surveillance Center reported the percent of active military members who experienced medical
encounters for overweight or obesity significantly increased. The estimated total days of
work lost from absenteeism associated with active-duty personnel who are overweight or obese
was 658,000. Using Department of Defense (DOD) estimates of average daily based, it was
estimated that overweight and obesity costs the DOD $103 million dollars in health care costs
annually. Note this estimate is for active duty personnel only. Furthermore, obesity is a
major cause for the discharge of uniformed personnel.
The current study is inspired by the successful Look Ahead trial, a behavioral science
obesity intervention treatment program that included: a collaborative approach, education,
behavioral support, and motivational interviewing. The unique nature of this weight reduction
study is significant. To our knowledge, there had not been a successful translation of a
highly efficacious obesity treatment in the military until The University of Tennessee Health
Science Center implemented a pilot version of the Fit Blue program for active duty U.S. Air
Force members in 2013. Following a successful pilot and extant results from the Look Ahead
trial, Investigators expect success during the full scale Fit Blue study.

This study is a weight loss intervention program tailored to a military population.
Investigators will randomize 204 consented participants to either an intensive
counselor-initiated weight loss intervention or a self-paced weight loss intervention.
Neither of the aforementioned conditions are controls and both treatments are expected to
result in weight reduction.
Procedures: This is a two-arm individually randomized trial. The Counselor-initiated group
will follow a more intense counselor-initiated approach, where the counselor schedules weekly
telephone sessions and contacts them directly. The Self-paced group uses a less intense
approach, where the participants can receive the same telephone counseling sessions as the
counselor-initiated group, only if they call the counselor.
Potential participants will be recruited through the use of advertisements, electronic
bulletins, emails, newspapers, and word-of-mouth. Prior to randomization, interested
individuals will complete a phone screening, informed consent, two in-person data collection
visits and obtain medical clearance, as well as participate in 1 week of dietary and physical
activity self-monitoring.
The randomized participants will spend the next year involved in study interventions (either
the Counselor-Initiated intervention or the Self-Paced intervention), diet and exercise
self-monitoring, daily weighing, and may also include telephone counseling sessions.
The follow-up data collection visits will occur at 4 and 12 months after randomization. At
these visits, physical measurements will be collected (i.e. height, weight, abdominal
circumference, blood pressure and heart rate) and participants will complete various
questionnaires. A Quality of Life questionnaire will also be administered by study personnel.
