P-Ratio: Where Surplus or Deficit Goes

P-ratio = (lean change) / (total change). Higher protein and bodyfat shift it toward lean.

P-Ratio: Where Surplus or Deficit Goes

P-Ratio: Where Weight Loss Comes From

Forbes-style P-ratio curves: as starting bodyfat percent rises, the proportion of weight lost from fat increases (and from muscle decreases). Mirror image during a surplus. Protein intake and training shift each curve favorably. The diagram quantifies "leaner people lose muscle faster on a cut."

  • Articles on minimum bodyfat for a cut
  • Bulking strategy and starting-bodyfat content

Source & accuracy

This p-ratio: where surplus or deficit goes is an editorial illustration built to represent the concept accurately. Where it shows figures, they are typical or representative values chosen to make the relationship clear, not a single underlying dataset. The diagram and its explainer are reviewed and maintained centrally, and updated over time as understanding improves.

What the P-ratio captures

The partitioning ratio, or P-ratio, describes how a change in body weight splits between lean tissue and fat. Defined as the change in lean mass divided by the total change in mass, a higher P-ratio in a surplus means more of the gain is muscle, and in a deficit a favorable ratio means more of the loss is fat with less lean tissue sacrificed.

It is a way of asking not just how much weight moved but what kind of tissue moved, which matters far more for body composition than the scale alone.

What nudges the ratio

Higher protein intake and resistance training push the ratio toward lean in both directions. Starting body fat also matters: more stored fat tends to favor fat loss over lean loss in a deficit. Genetics, training status, sleep, and the size of the surplus or deficit all influence the outcome.

P-ratio is a useful concept rather than a precisely controllable dial, and individual results vary widely. This is general educational information, not medical or training advice.
