The primary aim of this study is to compare the changes in body weight between a
technology-based system, an in-person behavioral weight loss intervention, and a combination
of both during a 12 month behavioral weight loss intervention in adults. Sedentary, healthy
overweight and obese adults will be recruited to participate. Assessments will be conducted
at 0, 6, and 12 months. This is a randomized trial in which participants will be randomized
to one of three groups: standard behavioral weight loss (SBWL), standard behavioral weight
loss plus technology (SBWL+TECH), and technology alone alone (TECH).


Inclusion Criteria:

Exclusion Criteria:

- Currently pregnant, pregnant in the last 6 months, or plan on becoming pregnant in
the next 6 months.

- Currently being treated for coronary heart disease, diabetes mellitus, hypertension,
or cancer.

- Have a history of myocardial infarction or other heart-related surgeries.

- Have a resting systolic blood pressure > 150 mmHg or diastolic blood pressure of >

system, an existing internet connection provided by the participant, and a dedicated
USB port to allow the armband from the technology system to be connected to the
computer for the download of information.
