Capturing Food Intake in Patients Undergoing Radiation Therapy for Cancer

June 26, 2026 updated by: University of Minnesota

The purpose of this study is to determine the feasibility of capturing daily dietary intake of patients undergoing radiation therapy using a mobile food record. This is a prospective single group, non-randomized, feasibility study.

20 participants will be identified during routine clinical care visits with the study PI or co-investigators. Consent will be obtained in person during a clinic visit or using the e-consent process described in section 21.1. They will be asked to use the myCircadian Clock (mCC) app to document their dietary intake for the duration of their radiation treatment. No follow up data will be collected.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Mobile Food Record
Participants will use the myCircadian Clock (mCC) app to document all dietary intake throughout the course of their radiation therapy.
Behavioral: Mobile food record using myCircadian Clock app
Participants will use the myCircadian Clock (mCC) app to document all dietary intake. The mCC app serves as a research-based mobile food record by capturing the food image coupled with the participant's free-text entry to self-describe the food. The participants will be asked to document all dietary intake throughout the course of their radiation therapy. All dietary intake will be tracked other than water and medications.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Feasibility of completing mobile food record during radiation therapy
Time Frame: Throughout the course of radiation therapy, which can last from 1 to 35 business days.
We hypothesize that it is feasible for patients undergoing radiation therapy to comply with completing a mobile food record. Feasibility is defined as 75% of the participants completing the dietary intake on at least 80% of the days that they are undergoing radiation therapy.
Throughout the course of radiation therapy, which can last from 1 to 35 business days.
