近日，巴西研究人員的一項研究發(fā)現(xiàn),，做過吸脂術(shù)的女性往往會長出更多深層脂肪,，這種脂肪非常不利于健康。如果想通過吸脂術(shù)減肚子,，必須確保術(shù)后堅持鍛煉,，否則肚子上恐怕會長出更多的肉。
圣保羅大學(xué)貝納蒂(Fabiana Benatti)領(lǐng)導(dǎo)的此項研究發(fā)現(xiàn),，在做過腹部吸脂術(shù)幾個月內(nèi)，在腹部器官周圍可能長出更多的內(nèi)臟脂肪。
但研究人員刊登在《臨床內(nèi)分泌學(xué)與代謝期刊》（The Journal of Clinical Endocrinology & Metabolism）的研究報告指出,，好消息是,，術(shù)后如果堅持鍛煉，也許能防止深層脂肪形成,。
貝納蒂在電子郵件中稱,，脂肪不是“惰性組織”，通過手術(shù)消除脂肪可能產(chǎn)生嚴重后果,，比如內(nèi)臟脂肪補償性生長,，這長期而言不利于健康。
與腹部皮下脂肪相比,，內(nèi)臟脂肪更容易引發(fā)2型糖尿病和心臟病,。
整體而言，專家認為不能用吸脂術(shù)代替健康飲食和鍛煉,。美國整形外科醫(yī)師協(xié)會稱,，吸脂術(shù)應(yīng)主要針對頑固脂肪，不宜用于治療肥胖,。
該協(xié)會認為,，最適合做吸脂術(shù)的,，是正常體重或略超重,、并且堅持鍛煉的人群。（生物谷Bioon.com）

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.
