SUMMARY

Controlled metabolic study used here for the disconfirmation arc. Using stable-isotope methods and body-composition measurement, the authors compared Hay's food-combining diet with a calorie-matched conventional mixed diet and found no advantage for the Hay diet in body weight or body composition (reported body weights were essentially equal, on the order of 72 kg in both conditions). The study is a small metabolic comparison, not a longevity trial, and is cited only for the narrow point that separating starches from proteins produced no measurable benefit over a mixed diet of the same energy. Identifiers confirmed against the PubMed record (PMID 11924853) and the DOI resolver (10.1080/10256010108033298).

NOTES

The Wutzke et al. 2001 study in Isotopes in Environmental and Health Studies is a controlled metabolic comparison of the Hay food-combining diet against an energy-matched conventional mixed diet. Measuring substrate oxidation by stable-isotope tracer and assessing body composition, it found no advantage for food separation: body weight and body composition were effectively the same under the Hay diet as under the mixed control. It is cited here for one bounded point in the disconfirmation, that the act of separating concentrated starches from concentrated proteins yields no measurable metabolic or body-composition benefit when calories are held equal. It is a small modern metabolic study and is not evidence about lifespan; the case does not present it as such. Identifiers were confirmed on PubMed (PMID 11924853) and the DOI resolver (10.1080/10256010108033298).
