Intermittent Fasting and Time-Restricted Eating

Evaluate the benefits and risks of time-restricted feeding for older adults, focusing on autophagy, muscle preservation, and energy.

Intermittent fasting promotes autophagy (cellular cleanup), but strict long fasts can risk muscle loss in older populations.

12:12 or 14:10 Windows: Fasting overnight for 12–14 hours is gentle and supports metabolic flexibility without risking inadequate protein intake during eating windows.
Priority: Always ensure daily protein targets are met during eating periods to avoid muscle wasting.
