MySnackTracker snack-only tracking versus full food tracking

Assessing User Satisfaction and Adherence to an Abbreviated Dietary Tracking App (MySnackTracker) Versus Full-intake Dietary Monitoring

Not applicable Interventional M.D. Anderson Cancer Center · NCT06919471

This tests whether a simplified snack-only app (MySnackTracker) helps adults with BMI 28–40 stick with and enjoy diet tracking more than traditional full food logging.

What this trial studies

The study compares an abbreviated food-logging approach that records only high-energy, low-nutrient snacks using the MySnackTracker app with standard full-intake dietary monitoring. Participants are adults drawn from specific prior DFI cohorts who have a smartphone, internet access, and a BMI between 28 and 40. Outcomes include adherence to logging, acceptability/satisfaction, and a range of secondary measures such as weight change, dietary intake metrics, self-efficacy scores, and activity questionnaire results. The intervention includes use of the MySnackTracker app and Fitbit monitoring during the study period.

Who should consider this trial

Good fit: Ideal candidates are adults (18+) with BMI 28–40 who previously participated in listed DFI cohorts, can read English, have a smartphone and internet access, and are willing to use the app and Fitbit.

Not a fit: People with BMI below 28 or above 40, pregnant women, those who are cognitively impaired, prisoners, non-English speakers, or those with prior or planned bariatric surgery are not likely to receive benefit from participation.

Why it matters

Potential benefit: If successful, this approach could make dietary self-monitoring easier to maintain and improve long-term adherence and satisfaction with tracking.

How similar studies have performed: Some prior research on simplified or targeted dietary logging has shown improved short-term adherence, but direct comparisons to full-intake monitoring remain limited.
