The purpose of this study was to compare the dietary strategies, and use of fat- and sugar-modified foods and beverages in a weight loss maintainer group (WLM) and an always-normal weight group (NW).
WLM (N=172) had maintained > or = 10% weight loss for 11.5 years, and had a body mass index (BMI) of 22.0 kg m(-2). NW (N=131) had a BMI of 21.3 kg m(-2) and no history of being overweight. Three, 24-h recalls on random, non-consecutive days were used to assess dietary intake.
WLM reported consuming a diet that was lower in fat (28.7 vs 32.6%, P<0.0001) and used more fat-modification strategies than NW. WLM also consumed a significantly greater percentage of modified dairy (60 vs 49%; P=0.002) and modified dressings and sauces (55 vs 44%; P=0.006) than NW. WLM reported consuming three times more daily servings of artificially sweetened soft drinks (0.91 vs 0.37; P=0.003), significantly fewer daily servings of sugar-sweetened soft drinks (0.07 vs 0.16; P=0.03) and more daily servings of water (4.72 vs 3.48; P=0.002) than NW.
These findings suggest that WLM use more dietary strategies to accomplish their weight loss maintenance, including greater restriction on fat intake, use of fat- and sugar-modified foods, reduced consumption of sugar-sweetened beverages and increased consumption of artificially sweetened beverages. Ways to promote the use of fat-modified foods and artificial sweeteners merits further research in both prevention- and treatment-controlled trials.
本研究旨在比较减肥维持者组(WLM)和一直正常体重组(NW)的饮食策略,以及脂肪和糖改性食品和饮料的使用情况。
WLM(N=172)保持>或= 10%的体重减轻 11.5 年,且体重指数(BMI)为 22.0 kg m(-2)。NW(N=131)BMI 为 21.3 kg m(-2),且没有超重史。在任意非连续三天随机选择三天进行 24 小时回顾性饮食记录,以评估饮食摄入量。
WLM 报告称,他们的饮食中脂肪含量较低(28.7%比 32.6%,P<0.0001),并且比 NW 更多地采用脂肪改性策略。WLM 还显著更多地食用改性乳制品(60%比 49%;P=0.002)和改性调味品(55%比 44%;P=0.006)。WLM 报告称,每天食用三倍以上的人工甜味软饮料(0.91 比 0.37;P=0.003),显著减少了每天含糖软饮料的摄入量(0.07 比 0.16;P=0.03),并增加了每天的水摄入量(4.72 比 3.48;P=0.002)。
这些发现表明,WLM 采用了更多的饮食策略来维持体重减轻,包括限制脂肪摄入、使用脂肪和糖改性食品、减少含糖饮料的消耗以及增加人工甜味饮料的消耗。在预防和治疗对照试验中,进一步研究促进使用脂肪改性食品和人工甜味剂的方法是值得的。
