导读：减肥从来就不是一件轻松事！有人懒得锻炼，想通过吸脂术一劳永逸地减掉身上的赘肉，但事实证明没那么简单！巴西研究发现，做过吸脂术后，如果不坚持锻炼，身上会长出更多肥肉。
巴西一项研究发现，做过吸脂术的女性往往会长出更多深层脂肪，这种脂肪非常不利于健康。如果想通过吸脂术减肚子，必须确保术后坚持锻炼，否则肚子上恐怕会长出更多的肉。
圣保罗大学贝纳蒂(Fabiana Benatti)领导的此项研究发现，在做过腹部吸脂术几个月内，在腹部器官周围可能长出更多的内脏脂肪。
但研究人员刊登在《临床内分泌学与代谢期刊》（The Journal of Clinical Endocrinology & Metabolism）的研究报告指出，好消息是，术后如果坚持锻炼，也许能防止深层脂肪形成。
贝纳蒂在电子邮件中称，脂肪不是“惰性组织”，通过手术消除脂肪可能产生严重后果，比如内脏脂肪补偿性生长，这长期而言不利于健康。
与腹部皮下脂肪相比，内脏脂肪更容易引发2型糖尿病和心脏病。
整体而言，专家认为不能用吸脂术代替健康饮食和锻炼。美国整形外科医师协会称，吸脂术应主要针对顽固脂肪，不宜用于治疗肥胖。
该协会认为，最适合做吸脂术的，是正常体重或略超重、并且坚持锻炼的人群。
Liposuction Induces a Compensatory Increase of Visceral Fat Which Is Effectively Counteracted by Physical Activity: A Randomized Trial

Context: Liposuction is suggested to result in long-term body fat regain that could lead to increased cardiometabolic risk. We hypothesized that physical activity could prevent this effect.
Objective: Our objective was to investigate the effects of liposuction on body fat distribution and cardiometabolic risk factors in women who were either exercise trained or not after surgery.
Design, Setting, and Participants: Thirty-six healthy normal-weight women participated in this 6-month randomized controlled trial at the University of Sao Paulo, Sao Paulo, Brazil.
Interventions: Patients underwent a small-volume abdominal liposuction. Two months after surgery, the subjects were randomly allocated into two groups: trained (TR, n = 18, 4-month exercise program) and nontrained (NT, n = 18).
Main Outcome Measures: Body fat distribution (assessed by computed tomography) was assessed before the intervention (PRE) and 2 months (POST2), and 6 months (POST6) after surgery. Secondary outcome measures included body composition, metabolic parameters and dietary intake, assessed at PRE, POST2, and POST6, and total energy expenditure, physical capacity, and sc adipocyte size and lipid metabolism-related gene expression, assessed at PRE and POST6.
Results: Liposuction was effective in reducing sc abdominal fat (PRE vs. POST2, P = 0.0001). Despite the sustained sc abdominal fat decrement at POST6 (P = 0.0001), the NT group showed a significant 10% increase in visceral fat from PRE to POST6 (P = 0.04; effect size = −0.72) and decreased energy expenditure (P = 0.01; effect size = 0.95) when compared with TR. Dietary intake, adipocyte size, and gene expression were unchanged over time.
Conclusion: Abdominal liposuction does not induce regrowth of fat, but it does trigger a compensatory increase of visceral fat, which is effectively counteracted by physical activity.
