Subjects
Twenty-four overweight and obese (body mass index=34.3±1.2) adults (seven men, 17 women) with a mean age of 61.3±1.1 years (range=55 to 75 years) were recruited from a local university community for this investigation. Subjects were weight-stable (±2 kg for more than 1 year, determined by self-report), nonsmokers, without major chronic disease (ie, diabetes, coronary heart disease), and not taking medications known to influence food intake or body weight. Participants had no food allergies or
Results and Discussion
Energy intake consumed during the two test meals is shown in the Figure. As with meal energy intake, the gram weight of food consumed at the test meals was also less in the water preload condition as compared with the no-preload condition (611±31 vs 663±36 g, respectively; P=0.023). Dietary energy density did not differ between the two test meals (water preload: 0.83±0.03; no water preload: 0.87±0.04, P=0.13). Participants consumed significantly less energy at the test meal after the water
Conclusions
Premeal water consumption reduced meal energy intake in overweight and obese older adults, suggesting that this may be an effective weight-control strategy for this segment of the population, particularly because habitual water consumption seems to be substantially less than recommended levels. The latter issues seem to be important areas for future investigation considering recent data indicating that adults 60 years of age and older have a higher prevalence of overweight and obesity (71%)

2021, Clinical NutritionCitation Excerpt :The association between drinking water consumption and BW in the long-term has been poorly studied [11,19]. To date, most research efforts have focused on the short-term effects of drinking water on total energy intake [20–23] and BW [24]. Intervention studies which have explored the effect of fluid consumption before a meal on energy intake have reported inconsistent results [20–23].

2018, Physiology and BehaviorCitation Excerpt :Numerous studies have assessed the potentially hypophagic effect of water when used as a meal pre-load. Several of these have found that a water pre-load immediately before a meal decreases energy intake during a subsequent meal [12,14,41]. Other studies, however, have found no effect of water intake on energy intake [10,15,28,29].
