Summary

This study looks at whether time-restricted eating (eating only during certain hours) can improve heart and brain health in 152 women aged 60-85 who finished chemotherapy for early-stage breast cancer at least a year ago. Participants will get counselling on when to eat and how to get enough protein. The goal is to see if this approach can lower heart disease risk and slow down memory and thinking problems.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Time restricted eating (TRE) with protein intake counselling
What this could lead to: If it works, this could point toward a lifestyle approach to protect heart and brain health in older breast cancer survivors after chemotherapy.
What could go wrong: This is a small, early-stage study (152 participants) testing a behavioural change, not a drug. Results may not apply to all survivors, and sticking to the eating schedule may be hard for some.
