Trial Summary

Do I need to stop my current medications for the trial?

The trial does not specify if you need to stop your current medications, but it excludes those on medications that significantly affect metabolic study markers. It's best to discuss your specific medications with the trial team.

What data supports the effectiveness of the treatment Time-restricted eating plus healthy diet for liver cancer?

Research shows that time-restricted eating can help prevent liver damage and cancer progression in experimental models. It reduces inflammation and supports liver health, which may help in managing liver cancer.12345

Is time-restricted eating safe for humans?

Research on time-restricted eating in animals suggests it may have protective effects against cancer and improve liver health, but it can also increase collagen deposits and enhance certain cancer risks in specific conditions. While these studies provide insights, more research is needed to confirm safety in humans.12346

How does time-restricted eating plus a healthy diet differ from other treatments for liver cancer?

Time-restricted eating combined with a healthy diet is unique because it focuses on limiting the hours during which food is consumed, which may help prevent liver cancer by reducing inflammation and supporting the liver's natural rhythms. This approach is different from traditional treatments that often involve medication or surgery, as it uses dietary timing and nutrition to potentially slow cancer progression.278910

What is the purpose of this trial?

This is a feasibility study that will collect data to assess the potential effect of a nutritional intervention designed to improve liver metabolism. This prospective single-site trial will enroll adult patients undergoing liver-directed therapies for hepatocellular carcinoma. Eligible individuals who are randomized to the intervention group will be enrolled in a six-month nutritional change program consisting of time-restricted eating in which calorie consumption is limited to 8-10 hours during the day, plus targeted healthy changes in what they eat. The intervention includes dietary counseling visits with a study registered dietitian and motivational phone calls with a study Certified Health and Wellness Coach to help subjects adhere to the intervention. Individuals in the control group will be enrolled in a six-month period of observation only. The main questions it aims to answer are:Is a prolonged nightly fast coupled with a healthy diet safe and feasible for patients with liver cancer? Does the intervention improve liver metabolism?

Findings from Research

Daily caloric restriction (CR) offers more effective protection against tumor growth and lung metastasis in a breast cancer model compared to periodic caloric cycling with a fasting-mimicking diet (FMD).
The enhanced cancer protection from daily CR may be linked to a distinct immune response that is not replicated by the FMD, suggesting that the consistency of dietary restriction plays a crucial role in cancer prevention.
Daily caloric restriction limits tumor growth more effectively than caloric cycling regardless of dietary composition.Pomatto-Watson, LCD., Bodogai, M., Bosompra, O., et al.[2023]
Time-restricted feeding (TRF) significantly reduced the expression of genes related to lipid metabolism in mammary tumors, suggesting a potential mechanism for its protective effects against tumor development.
Despite TRF not altering the overall metabolic profile of the tumors, its protective effects may be due to changes in the host's biological pathways rather than direct effects on tumor metabolism.
Metabolome of Mammary Tumors Differs from Normal Mammary Glands But Is Not Altered by Time-restricted Feeding Under Obesogenic Conditions.Yan, L., Sundaram, S., Rust, BM., et al.[2020]
Short-term dietary restriction, involving alternate day feeding and fasting, significantly improved survival rates in tumor-bearing Fisher rats, with 66.7% surviving 9 days post-tumor inoculation compared to only 20.8% in the control group.
The study suggests that mild dietary restrictions could be beneficial in enhancing survival and potentially inhibiting cancer growth, indicating a need for further clinical trials in human cancer patients.
