Researchers have randomly assigned 811 overweight adults to low-calorie diets with differing percentages of energy derived from protein, carbohydrate, and fat; participants were followed up for 2 years. All groups experienced modest weight loss and improvements in cardiac and diabetes risk factors. Does this finding mean that clinicians can finally advise their patients on the best way to lose weight?
研究人员将811名超重成年人随机分配到低热量饮食组，这些饮食中蛋白质、碳水化合物和脂肪的能量占比各不相同；对参与者进行了为期2年的随访。所有组的体重均有适度减轻，心脏和糖尿病风险因素也有所改善。这一发现是否意味着临床医生最终可以就最佳减肥方法向患者提供建议呢？
