This study evaluated which was the main nutritional change associated with weight reduction of overweight adult participants of a lifestyle change program. It was hypothesized that increases in dairy intake could be an important nutrition intervention in a lifestyle change program. 117 individuals, male (19.5%) and female (80.5%), with a minimum age of 36 years (54.2 ± 10.4). All study participants were enrolled in a lifestyle change program consisting of nutritional counseling and physical activity during 20 weeks. All participants were grouped in three groups according to Body Mass Index (BMI) delta median (-0.87 kg/m2) of individuals that showed weight loss: G1 - lost more than 0.87 kg/m2 of BMI (n = 38); G2 - lost 0 to 0.87 kg/m2 of BMI (n = 36); and G3 - increased BMI (n = 43). G1 increased dairy, fruit and vegetables intake and after forward stepwise multiple regression analysis, it was noted that an increase in dairy product intake of 0.40 servings per day had an impact of 9.6% on the loss of one kg/m2 of BMI. In conclusion, an increase in dairy product intake was the main dietary factor associated with reductions in body weight in overweight adults after 20 weeks of lifestyle change program.
本研究评估了在一项生活方式改变计划中，与超重成年参与者体重减轻相关的主要营养变化是什么。研究假设增加乳制品摄入量可能是生活方式改变计划中的一项重要营养干预措施。117名个体，男性（19.5%），女性（80.5%），最小年龄为36岁（54.2±10.4）。所有研究参与者都参加了一项生活方式改变计划，该计划包括在20周内提供营养咨询和体育活动。根据体重减轻个体的体重指数（BMI）变化中位数（-0.87kg/m²），将所有参与者分为三组：G1组——BMI降低超过0.87kg/m²（n=38）；G2组——BMI降低0至0.87kg/m²（n=36）；G3组——BMI增加（n=43）。G1组增加了乳制品、水果和蔬菜的摄入量，经过向前逐步多元回归分析发现，每天乳制品摄入量增加0.4份对BMI每降低1kg/m²有9.6%的影响。总之，在进行20周的生活方式改变计划后，乳制品摄入量的增加是超重成年人体重减轻的主要饮食因素。
