Pick a Window You Can Sustain
A 12:12 or 14:10 schedule is often enough to improve appetite control and meal quality. Extreme fasting windows can backfire if sleep, mood, or training quality drop.
High-intent readers should focus on consistency first: align your eating window with work, family, and workouts.
Protect Lean Mass
Prioritize protein at each meal and include resistance training two to four days weekly. Muscle is a major predictor of healthy aging.
If your fasting protocol lowers total protein intake, shift to a more flexible schedule instead of forcing compliance.
Metrics to Watch
Track waist circumference, fasting glucose, and energy levels over eight weeks. Use trends rather than day-to-day noise.
Adjust meal timing when sleep fragmentation, irritability, or poor training recovery show up.
