Overview
- A pooled, secondary analysis published Friday in the journal Appetite used video of 86 adults eating lab lunches and found each extra 100 grams of water was associated with about 39 grams more food consumed.
- Researchers reported that more frequent switching between bites and sips was tied to higher intake, with each additional switch linked to roughly 4.4 grams more food, a pattern the authors say could delay sensory‑specific satiety.
- A related April experiment with 49 adults found that spicier salsa slowed eating by about 30 percent and cut total snack intake by about 28 percent, suggesting heat can reduce consumption by slowing bite rate.
- The authors stress these results are associative secondary analyses of small, controlled lab trials using a narrow set of foods and cannot prove causation, and they are planning follow‑up experiments to test causal effects.
- If the findings hold in larger, real‑world studies, common advice to drink water during meals as a weight‑loss tactic may need reevaluation and researchers warn clinicians and consumers not to change behavior on these early results alone.
