Food Talk: A New App for Daily Food Monitoring

Study Overview
=================
Brief Summary
-----------------
This project will pilot test a new app for self-monitoring food intake using natural spoken language (by voice recognition or text) to provide daily estimates of energy and nutrient intakes with a phone app.

Detailed Description
-----------------
Self-recording food intake is recommended for weight management and healthy eating. However, current methods, including web platforms and apps, are often burdensome leading to short-term use by the consumer. The solution uses cutting-edge speech and language understanding technology to streamline the food logging process. With this technology, the user simply describes what they ate and the system automatically selects the appropriate items and quantities consumed from the USDA food database, which calculates the nutrition profile of the entry.

How is the study designed?
-----------------

Arms and Interventions

| Intervention/Treatment |
| --- |
|Behavioral: COCO application|All participants will complete a screening survey to determine their eligibility for the study, if eligible and willing to participate, he or she will sign an informed consent form. Once participants are enrolled in the study, a demographics questionnaire will be completed along with 5 days of food tracking on the COCO application. Between days 3 and 7, participants will complete two 24-hr diet recall, one a day, and a patient satisfaction questionnaire.|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in energy intake using food application COCO | The primary outcome will be to assess whether food capture using the mobile application is comparable with conventional 24-hour dietary recall. This will be done by measuring the energy intake (mean of two days) in the two methods. | Between days 3 and 7 of the study | 
| Change in energy intake using 24 hour dietary recall | The primary outcome will be to assess whether food capture using the mobile application is comparable with conventional 24-hour dietary recall. This will be done by measuring the energy intake (mean of two days) in the two methods. | Between days 3 and 7 of the study | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Accuracy of food capture method using mobile application | The secondary outcome will measure the energy and nutrient content reported by the mobile application over time. Measured energy intake in a subset of participants in another study that provides dietary intake data will be compared to food intake data using the mobile application. | Between days 3 and 7 of the study |
