The Difference Between Feeling Rested and Being Recovered

In almost every domain of the exercise and nutrition literature, consistency dominates intensity over any horizon that matters. The person who trains moderately for years outperforms the one who trains ferociously for months and then quits. The data keeps pointing at the same unglamorous conclusion: show up, repeatedly.

Beware the study that measures a biomarker and asks you to imagine the outcome. Moving a number on a panel is not the same as living longer or better, and the history of medicine is littered with interventions that improved the surrogate while doing nothing, or worse, to the thing you actually cared about. Demand the hard endpoint.

You can triage most nutrition headlines in half a minute. Ask whether it describes a randomized trial or an observational association, whether the effect size is meaningful or merely significant, and whether the outcome is something you care about or a proxy for it. Most breathless coverage does not survive those three questions.
