Summary

This study tests whether eating all meals within an 8-hour window (before 10 AM) for four weeks can improve how well older adults respond to seasonal flu and COVID-19 vaccines. Researchers will measure changes in immune cell activity and body composition in 24 healthy volunteers aged 60-85. The goal is to see if this simple eating pattern can help counter age-related immune decline.

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 (8-hour eating window)
What this could lead to: If it works, this could point toward a simple lifestyle change to help older adults get a stronger immune response from vaccines.
What could go wrong: This is a very small early study (24 people) looking at biological markers, not actual illness prevention. Results may not apply to everyone.
