What this study is about
This clinical trial is focused on testing dietary self-monitoring strategies used in behavioral obesity treatment. The goal is to determine which self-monitoring strategies are most useful for whom, at which points in treatment, and under what circumstances.
View original scientific description
This clinical trial is focused on testing dietary self-monitoring strategies used in behavioral obesity treatment. The goal is to determine which self-monitoring strategies are most useful for whom, at which points in treatment, and under what circumstances. Researchers will provide a 24-week online behavioral obesity treatment program, and will randomize participants to use one of 5 dietary self-monitoring strategies every two weeks. The five strategies include: recording all food and drink consumed and corresponding energy intake (i.e., "calories") on 7 days per week; recording all food and drink consumed and corresponding energy intake (i.e., "calories") on 3 days per week; self-monitoring of dietary lapses (i.e. any eating/drinking likely to cause weight gain or put weight loss at risk); smartwatch-based monitoring of energy intake (i.e., "calories"); and self-monitoring of body weight only via smart scale. Participants will: * Follow a 24-week online program for weight loss and health improvement * Use the assigned self-monitoring strategy every two weeks * Meet with the researchers periodically via online video call and provide research data by answering questions via periodic online surveys.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
