    How this Study Works on Efforia

    How this Study Works on Efforia

    This is a single-arm, prospective study conducted over 30 to 90 days (1-3 months), depending on the study length selection and you made and hosted on Efforia under the Minimal Risk Umbrella protocol. The authors listed on the study page designed the protocol’s procedures and measures. Matthew Amsden is the Principal Investigator, with Dr. Viral Patel serving as the Sub-Investigator overseeing safety and adverse events.

    While Efforia did not author this study, Efforia collaborates with the providers of the products and services included in this study. When you purchase the required items, Efforia takes a transaction fee, making this study possible.

    While you could buy these products separately for a similar cost, Efforia bundles everything into one convenient purchase and adjusts your costs based on the products you’ve already purchased. We organize and provide instructions to create a seamless, data-driven research experience.

    This setup helps you track your progress and understand how the products and services in this study impact your life through detailed outcome reports. It empowers you to make informed decisions about future purchases and the use of your time.

    Your participation also contributes to valuable generalizable research findings, benefiting others who might not be able to afford such opportunities without guaranteed results.

    Equitable inclusion:If the cost is a concern, click the Efforia logo at the top of the page to explore other protocols. We offer a range of studies at different price points, including free options.

    Total study length: 30 to 90 days (1-3 months)

    Purpose of the Study

    Purpose of the Study

    The purpose of this study is to evaluate how a structured routine using the included product(s) and services affects weight-management–related outcomes and day-to-day wellbeing. The study aims to generate practical, real-world evidence that can guide participants and the broader community in making informed decisions about future use.

    Products & Services: This protocol includes the product(s) shown on the study page (e.g., a dietary supplement shipped to you) and Efforia’s guided study experience. Efforia provides clear instructions, timing, reminders, and secure outcome reporting.

    Outcome Measures: You will complete short check-ins and questionnaires that assess weight-management–related indicators (such as daily logs, energy/appetite self-ratings, and other brief surveys). Measurements are designed to be low-burden while still providing personal and overall insights.

    How findings contribute: De-identified results are aggregated to estimate overall effects in similar participants. This contributes to generalizable knowledge about real-world use of the included product(s) and routine.
