Two small but intriguing studies published in Appetite and Food Quality and Preference are challenging some long-held dietary assumptions. In the water study, researchers found that for every additional 100 g of water consumed during a meal, participants ate about 39 g more food — roughly 49 extra calories. Frequent switching between bites and sips amplified the effect further. In the spicy food study, participants who ate spicier salsa consumed 28% fewer total snack calories and ate 30% more slowly than those eating the mild version.

Gastroenterology experts welcomed the findings but urged restraint in clinical application. Both studies were short-term, lab-controlled experiments that didn't track weight changes or account for eating behavior later in the day.

Key Takeaways:

• Drinking water with meals may not reduce — and could increase — caloric intake, challenging a common dietary recommendation
• Spicy food may slow eating rate, which in turn reduces overall intake — but it's the slower eating pace, not the spice itself, that appears to be the key mechanism
• Patients with reflux or IBS aggravated by spicy foods should individualize this approach

Why it matters: These findings nudge clinicians to reconsider blanket advice like "drink water to eat less," and suggest that eating pace — not just food composition — may be an underutilized lever in weight management counseling.
