Claim guardrail

What this page should prevent.

Do not present fasting as a lean-mass protection strategy by itself. Resistance training and protein still carry that job.

Geebs coaching takeaway

The study only matters if it changes a behavior.

For body composition, fasting should be judged by the whole plan: calories, protein, lifting performance, sleep, hunger, and consistency.

Content angles

The window is not the whole diet

Fasting needs a muscle plan too
