当身体过度肥胖者减肥时,他们的骨质密度也常常下降,患骨质疏松症的几率也随之提高。但是一项最新的研究表明:如果能通过锻炼、而不是限制卡路里摄入量的办法来减肥,骨质的强度就能够得到维持。在一项为期一年的研究试验中,科学家们将48个50岁以上、健康且体重正常的人随机分成 When physically obese people lose weight, their bone density often decreases, and the risk of osteoporosis increases. But a new study shows that if you can lose weight by exercising rather than limiting your calorie intake, bone strength can be maintained. In a one-year research experiment, scientists randomly divided 48 people over 50 years old who were healthy and normal in weight.
