Food Talk: A New App for Daily Food Monitoring

Completed

• Conditions: Dietary Intake

• Registration Number: NCT03869658
• Lead Sponsor: Tufts University

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.

Primary Outcome Measures

Name	Time	Method
Change in energy intake using food application COCO	Between days 3 and 7 of the study	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.
Change in energy intake using 24 hour dietary recall	Between days 3 and 7 of the study	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.

Secondary Outcome Measures

Name	Time	Method
Accuracy of food capture method using mobile application	Between days 3 and 7 of the study	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.
