Remove it here, regrow it there. Body fat resembles the Hydra from Greek mythology
In order to control the outcome of the operation itself and its long(er) term consequences in the presence or absence of a physical exercise program that was conducted for four months starting 2 months after the OP (this yields a total duration of 6 months for the whole study), the Fabiana Benatti and her colleagues assessed the total body fat and fat-free mass of the participants via hydrostatic weighing and used computer tomographs to determine the size of the individual fat depots.

- 5-min warm-up followed by
- strength exercises: 8 exercises for the major muscle groups, 3 sets of 12 reps, and
- aerobic exercise on the treadmill: 30-40min at 75% of the VO2max
Could it be that taking the easier way out is always a bad idea?

The further reduction in subcutaneous fat and the absence of this highly unfavorable "repartitioning effect", on the other hand, speak to the effectiveness of a combined strength and endurance training program for female and, as we know from countless of other studies, also male weight loss - and that in the absence overtly restrictive eating.
Clear results with surprising effects on CVD risk and energy expenditure
Still, there are a few downsides and shortcomings to this study that should not be overlooked. Firstly, the scientists did not evaluate the body fat distribution in the upper body, specifically the breasts. Whether there may have been a repartitioning effect from the abdominal to the upper body (e.g. breast, back and arms) subcutaneous fat depots, thusly remains to be elucidated. Moreover the increase in total LDL count, the scientists observed in the non-training group was not accompanied by increases in ApoB levels, which are considered as a relatively reliable marker for the number of the allegedly artery-clogging small LDL particles. Whether the women in the study are thusly actually facing an increased risk for cardiovascular disease or simply carry ~10% more visceral body fat around is about as questionable as the underlying cause of the reduction in energy expenditure that went hand in hand with the loss of ~1kg of subcutaneous body fat in the absence of a reduced caloric intake.

our data suggest that the fat loss per se plays a role in decreased energy expenditure because no changes in food intake, lean mass, or leptin levels were observed.And call for "[a]dditional studies" to "comprehensively explore the underlying mechanisms of the liposuction-induced decrease in energy expenditure". In view of the fact that these results could be of fundamental importance not only for the lazy plastic surgery patient, but also for the hard-training physical culturist who strives to push his / her body fat levels lower and lower, you can be certain that the SuppVersity is the place, where you are going to read about the results of future investigations into the underlying mechanisms first!
