Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Body mass index (BMI) between 25-39.9 kg/m2
Exclusion Criteria
* Currently participating in regular exercise for over 60 minutes/week.
* Taking any medications that affect body weight or metabolism (e.g. synthroid).
* Have any physical limitations that would prevent exercise.
* 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 \> 100 mmHg or currently taking any medications that affect blood pressure or heart rate (e.g. beta blockers).
* Currently enrolled in a commercial weight loss program, participating in another weight loss study, or in a weight loss study in the last 12 months.
* Have lost \> 5% of current body weight in the past 6 months.
* Currently being treated for any psychological problems or taking any psychotropic medication.
* Currently do not have access to a computer and the Internet that can be used for this study. This requires a PC computer, the ability to load software for the technology 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.
