Weight loss among metabolically healthy obese (MHO) individuals may be unnecessary or result in elevated cardio-metabolic risk. We studied the effects of exercise- or diet-induced weight loss on cardio-metabolic risk among MHO and metabolically abnormal obese (MAO) adults.
Participants were 63 MHO and 43 MAO adults who took part in 3 to 6 months of exercise- or diet-induced weight loss intervention. Changes in anthropometry, adipose tissue distribution, and cardio-metabolic risk factors were assessed.
Body weight, waist circumference, and total abdominal and visceral adipose tissue were reduced in all subjects (P < 0.05). Improvements in insulin sensitivity were observed in MHO and MAO men and women (P < 0.05), but were greater in the MAO individuals (P < 0.05). Fasting insulin was the only other cardio-metabolic improvement among MHO individuals (P < 0.05).
Lifestyle-induced weight loss among MHO subjects is associated with a reduction in total and abdominal obesity and improvement in selected cardio-metabolic risk factors.
代谢健康型肥胖(MHO)个体的体重减轻可能是不必要的,或者会导致心血管代谢风险升高。我们研究了运动或饮食诱导的体重减轻对 MHO 和代谢异常肥胖(MAO)成年人的心血管代谢风险的影响。
参与者为 63 名 MHO 和 43 名 MAO 成年人,他们参加了 3 至 6 个月的运动或饮食诱导的体重减轻干预。评估了人体测量学、脂肪组织分布和心血管代谢危险因素的变化。
所有受试者的体重、腰围以及腹部和内脏总脂肪组织均减少(P<0.05)。MHO 和 MAO 男女的胰岛素敏感性均有所改善(P<0.05),但 MAO 个体的改善更为明显(P<0.05)。MHO 个体中唯一其他改善的心血管代谢因素是空腹胰岛素(P<0.05)。
MHO 受试者的生活方式诱导的体重减轻与总肥胖和腹部肥胖的减少以及某些心血管代谢风险因素的改善有关。
