Why we cite it
The foundational study in Brenda Davy's premeal water research program, demonstrating that the water preload effect on energy intake is age-specific — effective in older adults (60–80 years) but not younger adults (21–35 years). This age-specificity finding shaped the subsequent studies (cwa03, cwa02), which focused exclusively on older adults. Approximately 95 Semantic Scholar citations.
