Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The intervention uses a self-determination theory framework to provide a deeper understanding of the factors that influence dietary behavior within the context of tracking. This study incorporates autonomy-supportive strategies to encourage participants to feel more in control of their dietary choices and will provide information and resources to boost participant's competence in achieving their dietary goals. The intervention includes weekly learning modules to support healthy eating and weight loss and daily dietary tracking with visual feedback, all accessible within the SWITCH app.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Intervention Design:
Diet tracking. Participants in both groups will be asked to track all meals, snacks, and beverages via the SWITCH app and complete a weekly learning module. Both groups will receive the same intervention, but the targeted nutrient goals and the in-app display of daily intake will differ between groups. Participants will be given goals to either increase certain nutrients or to decrease certain nutrients.
Diet related education to support healthy eating and weight loss will be provided each week within the SWITCH app. Each module includes some or all (as applicable) of the following components: A brief educational video discussing the week's topic, a video sharing ideas for applying the educational content into daily life, "meal swap" examples, a weekly goal or challenge and example recipes.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
SWITCH tracking healthy nutrients
Participants allocated to this group will be given goals to reach a recommended daily intake of nutrients in which US adults tend to not consume enough. Recommended amounts will be based off of age and sex, in line with the US Dietary Guidelines.
learning modules (within app)
Behavioral:
Participants will have access to a weekly learning module created as Kahoot courses. Each module will include some or all (as applicable) of the following:
* A brief educational video discussing the week's topic
* A brief video sharing ideas for applying the educational content into daily life
* PDF of "meal swap" examples
* A weekly goal or challenge
* Recipes
SWITCH app (self-regulation features) - Experimental
Behavioral:
Diet (track by in app database). App homepage displays dietary intake graph -circles -. Participants will see an empty circles for the goal nutrients at the start of each day, which will fill up as the participant tracks his/her food intake. If the participant consumes an excess beyond the nutrient intake goal, the circle will remain entirely full.
standard SWITCH app
Participants in this group will be given goals to reduce intake of nutrients in which US adults tend to consume too much. Personalized daily intake goals for nutrients will be based on age, weight, sex, and the US Dietary Guidelines.

SWITCH app (self-regulation features) - Comparator
Diet (track by in app database). App homepage displays dietary intake graph -circles -.
Participants allocated to the control group, tracking intake of nutrients to lower, will see a full circle at the start of each day which depletes, or empties, as the participant tracks his/her food intake. If the participant consumes an excess beyond the nutrient intake goal, the circle will remain entirely empty and the reported totals below the intake circles will display the current intake totals.
