水的消耗严重降低了中老年人群的膳食能量摄入（EI）。我们的目的是确定餐前饮水是否有助于超重/肥胖中老年人的体重减轻，并确定餐前饮水是否能够在12周的增加饮水后持续减少餐前EI。成年人（n = 48； 55-75岁，BMI 25-40 kg/m2）被分为两组：(i)每天饭前低热量饮食+ 500毫升水（水组），或（ii）单独低热量饮食（非水组）。在基线和第12周，每位参与者进行两次随意试验餐：(i)无预负荷（NP）和（ii） 500毫升水预负荷（WP）。在每个试餐时评估饲粮EI，并在12周内每周评估体重。在12周的时间里，水组的体重下降幅度比非水组大约2 kg (β = - 0.87, P < 0.001)，水组的体重下降幅度比非水组大44% （β = - 0.60, P < 0.001）。在基线时，WP组的试验饲料EI低于NP组，但在第12周时没有（基线：WP 498±25 kcal， NP 541±27 kcal, P = 0.009；第12周：WP 480±25 kcal， NP 506±25 kcal, P = 0.069）。因此，当与低热量饮食相结合时，在每次主餐前喝500毫升水比单独低热量饮食对中老年人的减肥效果更大。这可能部分是由于摄入水后膳食EI的急剧减少。
Water consumption acutely reduces meal energy intake (EI) among middle-aged and older adults. Our objectives were to determine if premeal water consumption facilitates weight loss among overweight/obese middle-aged and older adults, and to determine if the ability of premeal water consumption to reduce meal EI is sustained after a 12-week period of increased water consumption. Adults (n = 48; 55–75 years, BMI 25–40 kg/m2) were assigned to one of two groups: (i) hypocaloric diet + 500 ml water prior to each daily meal (water group), or (ii) hypocaloric diet alone (nonwater group). At baseline and week 12, each participant underwent two ad libitum test meals: (i) no preload (NP), and (ii) 500 ml water preload (WP). Meal EI was assessed at each test meal and body weight was assessed weekly for 12 weeks. Weight loss was ~2 kg greater in the water group than in the nonwater group, and the water group (β = −0.87, P < 0.001) showed a 44% greater decline in weight over the 12 weeks than the nonwater group (β = −0.60, P < 0.001). Test meal EI was lower in the WP than NP condition at baseline, but not at week 12 (baseline: WP 498 ± 25 kcal, NP 541 ± 27 kcal, P = 0.009; 12-week: WP 480 ± 25 kcal, NP 506 ± 25 kcal, P = 0.069). Thus, when combined with a hypocaloric diet, consuming 500 ml water prior to each main meal leads to greater weight loss than a hypocaloric diet alone in middle-aged and older adults. This may be due in part to an acute reduction in meal EI following water ingestion.
