A Study of Time-Restricted Eating in Childhood Cancer Survivors

May 26, 2026 updated by: Memorial Sloan Kettering Cancer Center

Decreasing Cardiometabolic Risk in Childhood Cancer Survivors: The STRENGTH (Survivors Engaged in Time-Restricted EatiNG After THerapy) Study

This study will look at whether motivational sessions (including regular calls with a trained health coach) in combination with time-restricted eating (TRE) is an effective way to achieve weight loss and lower cardiometabolic risk in adult survivors of childhood cancer. The researchers will look at how effective this intervention is compared to the usual approach, which is to review educational materials and measure weight once a month. This study will not provide treatment for any disease or cancer.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Enrolled in the Childhood Cancer Survivor Study (a cohort of 5+ year survivors of childhood cancer diagnosed at age < 21 between 1970-1999 at 31 participating institutions in North America)
  • Are ≥18 years old
  • Self-reported body mass index ≥ 25 kg/m2
  • Are not pregnant or do not intend to become pregnant in the next year
  • Stable weight over the past 3 months (+/- 10 pounds)
  • If on oral medication for insulin resistance (ie, metformin), elevated blood pressure, or dyslipidemia, medication dose must be stable (ie, unchanged > 3 months)
  • Have internet access (can be via smartphone or computer). If neither device is available, the study can loan participants a Wi-Fi enabled device.

Exclusion Criteria:

  • Do not reside in the United States
  • Do not speak English
  • Eating window < 12 hours per 24-hour day
  • On insulin or GLP-1 agonist

Experimental: Intervention Group
Participants will be instructed to participate in time-restricted eating, building to a 16-hour fast per day (not eating or drinking calorie-enriched beverages such as soda or nutritional shakes for a 16-hour window, such as 6pm -10am or 7pm-11am). These participants will also receive motivational phone/video calls with a trained health coach, daily text message reminders of when to start and stop their fasting, and monthly weight check-ins.
