Recent studies suggest that calcium metabolism and perhaps other components of dairy products may contribute to shifting the energy balance and thus play a role in weight regulation. We compared the effects of cows' milk, calcium fortified soy milk and calcium supplement on weight and body fat reduction in premenopausal overweight and obese women.
In this clinical trial, 100 healthy overweight or obese premenopausal women were randomized to one of the following dietary regimens for 8 weeks: (1) a control diet providing a 500kcal/day deficit, with 500-600mg/day dietary calcium; (2) a calcium-supplemented diet identical to the control diet with 800mg/day of calcium as calcium carbonate; (3) a milk diet providing a 500kcal/day deficit and containing three servings of low-fat milk; (4) a soy milk diet providing a 500kcal/day deficit and containing three servings of calcium fortified soy milk. At baseline and after 8 weeks, weight, waist circumference, and hip circumference were measured. Three 24-h dietary records and physical activity records were also taken. Comparing the mean differences in weight, waist circumference, body mass index (BMI) and waist-to-hip ratio (WHR) using repeated measure of variance analysis showed that changes in waist circumference and WHR were significant among the four groups (p=0.029 and p=0.015, respectively). After adjustment for baseline values, changes in weight and BMI were also significant (p=0.017 and p=0.019, respectively). Weight reductions in high milk, soy milk, calcium supplement and control groups were 4.43±1.93(kg), 3.46±1.28(kg), 3.89±2.40(kg) and 2.87±1.55(kg), respectively. The greatest changes were seen in the high dairy group in all variables.
Increasing low fat milk consumption significantly reduces the general and central obesity beyond a low calorie diet.
最近的研究表明，钙代谢和乳制品的其他成分可能有助于改变能量平衡，从而在体重调节中发挥作用。我们比较了牛奶、钙强化豆浆和钙补充剂对绝经前超重和肥胖女性体重和体脂减少的影响。
在这项临床试验中，100 名健康超重或肥胖的绝经前女性被随机分为以下饮食方案之一，持续 8 周：（1）对照饮食提供 500kcal/天的热量不足，饮食中钙 500-600mg/天；（2）与对照饮食相同的钙补充饮食，每天 800mg 碳酸钙；（3）牛奶饮食提供 500kcal/天的热量不足，包含三份低脂牛奶；（4）含三份钙强化豆浆的豆浆饮食提供 500kcal/天的热量不足。在基线和 8 周后，测量体重、腰围和臀围。还记录了三份 24 小时饮食记录和身体活动记录。使用重复测量方差分析比较体重、腰围、体重指数（BMI）和腰臀比（WHR）的平均差异，结果表明四组的腰围和 WHR 变化均有显著性差异（p=0.029 和 p=0.015）。调整基线值后，体重和 BMI 的变化也有显著性差异（p=0.017 和 p=0.019）。高牛奶、豆浆、钙补充和对照组的体重减轻分别为 4.43±1.93(kg)、3.46±1.28(kg)、3.89±2.40(kg)和 2.87±1.55(kg)。高乳制品组在所有变量中的变化最大。
增加低脂牛奶的摄入可显著降低低热量饮食以外的一般和中心性肥胖。
