Exercise and low-calorie diets are common approaches taken to produce an energy deficit for weight loss in obesity. Changes in visceral and abdominal subcutaneous fat associated with weight loss are important questions but have not yet been concluded. We investigated the relationship between changes in visceral (VAT) and subcutaneous adipose tissue (SAT) areas obtained by abdominal imaging with the change in total body fat. The relevant databases were searched through January 2021 according to the PRISMA guidelines. Sixty-five studies were included. We found that the change in total body fat was associated with changes in both VAT and abdominal SAT areas, but the relationship between total body fat and the abdominal SAT area appeared stronger. Baseline values of VAT and abdominal SAT area were similar in the three treatment groups (calorie restriction, calorie restriction plus exercise, and exercise alone). The reduction in abdominal SAT area for a loss of 1 kg of total body fat was about 10 cm, which was similar among all the treatments. The change in VAT area (-26.3 cm) was a similar level as the change in abdominal SAT area (-31.5 cm) in the exercise, whereas in the calorie restriction with and without exercise, the change in VAT area (-33.6 and -51.6 cm, respectively) was approximately half of the reduction of SAT area (-65.1 and -87.2 cm, respectively). Absolute changes in VAT and abdominal SAT areas might differ between interventions for the exercise and calorie restriction with and without exercise.
运动和低热量饮食是肥胖症患者为实现能量负平衡以减轻体重而常用的方法。与体重减轻相关的内脏脂肪和腹部皮下脂肪的变化是重要问题，但尚未得出结论。我们研究了通过腹部成像获得的内脏脂肪组织（VAT）和皮下脂肪组织（SAT）面积变化与全身脂肪变化之间的关系。根据PRISMA指南，检索了截至2021年1月的相关数据库。纳入了65项研究。我们发现，全身脂肪的变化与VAT和腹部SAT面积的变化均相关，但全身脂肪与腹部SAT面积之间的关系似乎更强。三个治疗组（热量限制、热量限制加运动和单独运动）的VAT和腹部SAT面积基线值相似。全身脂肪减少1 kg时，腹部SAT面积减少约10 cm，在所有治疗中相似。运动组中，VAT面积变化（-26.3 cm）与腹部SAT面积变化（-31.5 cm）处于相似水平，而在有运动和无运动的热量限制组中，VAT面积变化（分别为-33.6和-51.6 cm）约为SAT面积减少量（分别为-65.1和-87.2 cm）的一半。运动以及有运动和无运动的热量限制干预措施之间，VAT和腹部SAT面积的绝对变化可能有所不同。
