Eating on a daily schedule to lower breast cancer risk

Time-restricted feeding and breast cancer

NIH-funded research University of California, San Diego · NIH-11142589

This project looks at whether restricting daily eating to a set time window can improve metabolism and lower breast cancer risk for people with obesity or higher risk.

What this research studies

Researchers are studying how limiting food to a daily time window (time-restricted feeding) changes weight, insulin, inflammation, and tumor behavior. They combine animal and lab studies with data relevant to humans to understand the biological links between obesity and breast cancer. The team compares outcomes from time-restricted eating versus typical eating patterns and measures effects on tumor growth and markers tied to metastasis. If you have obesity or are concerned about breast cancer risk, the findings could inform simple daily eating changes.

Who could benefit from this research

Good fit: Ideal candidates would be women with obesity or mid-to-late adulthood who are at increased risk for breast cancer, including breast cancer survivors worried about recurrence.

Not a fit: People without obesity, those whose cancer risk is driven by non-metabolic causes, or men may be less likely to benefit from the specific interventions studied here.

Why it matters

Potential benefit: If successful, this work could point to an easy-to-follow eating schedule that lowers breast cancer risk and improves metabolic health for people with obesity.

How similar studies have performed: Animal studies and small human trials show time-restricted feeding can improve metabolic markers, but evidence that it reduces breast cancer risk or recurrence is still limited.
