Study summary

The goal of the project is to test a remotely delivered, standalone behavioral weight loss intervention designed to help adults initiate the important dietary, physical activity (PA) and behavioral changes necessary to achieve weight loss.

Read the detailed description

The Weight Management Center currently offers a remotely delivered (smart phone, tablet, computer) program to assist patients with maintaining weight losses already achieved, which includes multi-channel self-monitoring and asynchronous individually recorded feedback from clinical staff. The goal of the presently proposed project is to build on this existing maintenance-focused program to create a remotely delivered, standalone behavioral weight loss intervention designed to help participants initiate the important dietary, physical activity (PA) and behavioral changes necessary to achieve weight loss. We recently developed the Home Weight Loss (HWL) program by repackaging existing clinical educational materials as instructional lifestyle change modules to be delivered remotely for participant weight loss

The aim of the proposed project are to pilot test the effects of the HWL program among a sample of overweight and obese adults (N=30). The digital platform currently used in the maintenance program will be used for the HWL program

Study arms

  • Experimental
    Home weight loss program

    Participants will be instructed to daily monitor their body weight, minutes of activity, number of steps, and calories consumed for the duration of the pilot study, and they will receive recorded individualized feedback on this self-monitored data from Weight Management Center clinicians (registered dietitians, exercise psychologists, and behavioral specialists).

    Behavioral: Home weight loss program

Interventions

  • BehavioralHome weight loss program

    Patient remote self-monitoring of diet, activity, and weight with clinician feedback provided remotely based on self-monitored data.

What researchers measure

Primary outcomes

  1. Body weight change

    body weight change (kg) from pre-to post

    Time frame: 12 weeks

Secondary outcomes

  1. changes in body weight as a percentage of start weight

    percent body weight change

    Time frame: 12 weeks

  2. changes in body mass index

    weight in kgs divided by height in meters squared to obtain BMI (kg/m\^2)

    Time frame: 12 weeks

  3. program satisfaction

    program satisfaction obtained from multiple choice items developed by study staff. Subjects are asked to rate their level of agreement with items assessing their satisfaction with the overall program, available responses range from extremely satisfied to not at all satisfied.

    Time frame: 12 weeks

  4. changes in body fat percentage

    changes in body fat percentage

    Time frame: 12 weeks

  5. changes in waist and hip measurements

    changes in waist and hip measurements

    Time frame: 12 weeks

  6. usability of program components

    examine usage of tracking components including step, exercise, diet, and weight tracking

    Time frame: 12 weeks

  7. changes in eating behavior scores

    use of the Eating Behavior Inventory (EBI). This is a validated 26-item scale assessing eating and weight control behaviors. Subjects indicate agreement with statements with reponse options ranging in values from 1 (never or hardly ever) to 5 (always or almost). Higher values are indicative of those most associated with weight loss (e.g., self-monitoring caloric intake) and are therefore associated with better weight loss outcomes following behavioral weight management intervention.

    Time frame: 12 weeks

  8. changes in scores on the power of food scale

    use of the Power of Food Scale (PFS). This is a validated 15-item scale with responses scored and ranging between 1 (do not agree) and 5 (strongly agree) with the statements. Higher scores indicate less favorable outcomes, as higher scores indicate increased patient susceptibility to food in the environment.

    Time frame: 12 weeks

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Feb 2018 to primary completion in Jul 2018, 4 months.

Of 1,356 non-industry interventional studies with no phase under Overweight, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 8 and three quarters within 38. This study's 4 months is below that.

Counting every sponsor, half of 1,472 studies reached it within 17 months; a quarter within 7 and three quarters within 36.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 9, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
