I determined whether water consumption reduces energy intake and affects satiety in non-obese young adults. The final subjects consisted of 15 individuals (8 women and 7 men) with average ages of 26.4 and 23.5 years for women and men, respectively. When subjects drank water before eating a test meal, they ate a lower amount of the test meal compared to eating test meals under waterless and postload water conditions (preload water: 123.3 g vs. waterless: 161.7 g or postload water: 163.3 g, p < 0.05). Water consumption after eating a test meal did not affect energy intake. When the subjects drank water before eating a test meal, despite consuming a lower amount, the subjects did not feel significantly less satiety than eating meals under waterless or postload water conditions. The finding that pre-meal water consumption led to a significant reduction in meal energy intake in young adults suggests that pre-meal water consumption may be an effective weight control strategy, although the mechanism of action is unknown.

We examined community-level characteristics associated with free drinking water access policies in U.S. municipalities using data from a nationally representative survey of city managers/officials from 2,029 local governments in 2014. Outcomes were 4 free drinking water access policies. Explanatory measures were population size, rural/urban status, census region, poverty prevalence, education, and racial/ethnic composition. We used multivariable logistic regression to test differences and presented only significant findings. Many (56.3%) local governments had at least one community plan with a written
objective
to provide free drinking water in outdoor areas; municipalities in the Northeast and South regions and municipalities with ≤ 50% of non-Hispanic whites were less likely and municipalities with larger population size were more likely to have a plan. About 59% had polices/budget provisions for free drinking water in parks/outdoor recreation areas; municipalities in the Northeast and South regions were less likely and municipalities with larger population size were more likely to have it. Only 9.3% provided development incentives for placing drinking fountains in outdoor, publicly accessible areas; municipalities with larger population size were more likely to have it. Only 7.7% had a municipal plumbing code with a drinking fountain standard that differed from the statewide plumbing code; municipalities with a lower proportion of non-Hispanic whites were more likely to have it. In conclusion, over half of municipalities had written plans or a provision for providing free drinking water in parks, but providing development incentives or having a local plumbing code provision were rare.
