Those three little letters are freighted with enough baggage to sink a cruise ship. the issue encompasses health and aesthetics, of course, but also self esteem, class, money, and politics. Then there is the moral component. After losing more than 40 pounds, Kelly Osbourne said, “I took more hell for being fat than I did for being an absolute raging drug addict — I will never understand that.” on the flip side, for those with a conscience (and we know you’re out there), the idea of obsessing over a problem that is often rooted in self-indulgence can make a person want to join the Sisters of Mercy and work off the guilt among people with real troubles. Yet even thin women are not exempt, as they may worry about a little roll at the waist, a hint of a double chin, jiggly arms, or chubby knees. No amount of Spinning or sit-ups can eliminate certain stubborn bulges or change the dictates of our genes.
Enter the plastic surgeon. in 2009, more than 243,000 women had liposuction to remove fat from various body areas, and about 123,000 underwent stomach-firming abdominoplasties. in recent years, doctors have developed several new — and nonsurgical — methods to reduce fat and sculpt the body. to help make sense of all the options, Allure asked experts to weigh in on how (and whether) these procedures work. And don’t be embarrassed about the tape measure. when it comes to fat, there are no silly questions.
What can getting liposuction do — and not do? Liposuction treats fat deposits that are resistant to diet and exercise, such as saddlebags or the lower abdomen, which means it’s not a substitute for traditional weight loss. in fact, diet and exercise are essential before and after the procedure to obtain the best results, says Jeffrey Kenkel, professor of plastic surgery at the University of Texas Southwestern Medical School. a doctor can suction out up to five quarts of fat, but there is usually little change in body weight — at most a pound or two. Liposuction can’t eliminate stretch marks or cellulite, and it may even make cellulite more pronounced, Kenkel says. once the fat is taken out, “we can’t predict or control how much the overlying skin will contract,” he says. “In general, patients with good skin tone will experience tightening as the skin redistributes itself. But others with thin, soft skin may develop sagging in the areas suctioned.” Doctors are developing alternative and noninvasive ways to remove fat, but for now liposuction is considered the gold standard.
Reduce fat, reuse it, recycle it. That’s the goal of a procedure called fat grafting, fat transfer, or lipofilling, in which a doctor injects the face with a patient’s body fat — from the abdomen, thighs, or buttocks — to smooth lines and fill hollows. many of the injected fat cells don’t survive, and there can be loss of volume over time, so doctors usually overfill the area to compensate. But the final outcome may still look overdone, and if a patient gains five to ten pounds, the grafted fat can grow, says Val Lambros, a plastic surgeon in Newport Beach, California. most problems (such as lumpiness or asymmetry) can be corrected by adding or removing fat, says J. Peter Rubin, associate professor of plastic surgery at the University of Pittsburgh and codirector of its Adipose Stem Cell Center.
Does lipo ever need revision? Yes — about 20 percent of patients request a redo, says Lori Brightman, director of dermatology at the New York Eye and Ear Infirmary. Common causes are unevenness (for example, one outer thigh not seeming symmetrical with the other) or a lumpy look, in which case the doctor can usually do a touch-up by removing more fat. another potential complication is track marks, the result of fat taken too close to the skin’s surface. “This is a lot harder to repair and in some cases may require transferring fat from somewhere else in the body,” Brightman says.
Once the fat is removed, can it come back? If you gain weight after the procedure, you may find it collecting in unlipo’d areas on the body. the redistribution is unpredictable, says Gerald H. Pitman, a plastic surgeon in New York City and clinical professor of plastic surgery at NYU School of Medicine. “Patients who gain weight after liposuction of the hips and thighs may say, ‘My arms are bigger’ or ‘My bra is tighter.’”
People are talking about laser lipo. What is it? In laser-assisted liposuction (LAL), fat is loosened with a laser before being suctioned out, which is why it can take twice as long to perform — for example, about 60 to 90 minutes for traditional liposuction of the abdomen versus 120 to 180 minutes for LAL, says Rhoda S. Narins, chief of liposuction in the dermatology department at NYU School of Medicine. the laser is said to stimulate collagen and elastin repair in the overlying skin and to result in less bruising than regular lipo, because it coagulates blood vessels. “You don’t need laser lipo for someone with good-quality skin. It’s for an older patient who has lost elasticity,” says Barry DiBernardo, clinical associate professor of plastic and reconstructive surgery at the University of Medicine and Dentistry of New Jersey in Newark. LAL is best for relatively small areas without thick fat, such as under the chin, he says. (In ultrasound-assisted liposuction, fat is also liquefied before suctioning.)
Some doctors are skeptical of using lasers this way, pointing out that there currently isn’t scientific data to support the claimed benefits. also, “you are potentially heating the skin to dangerous levels in order to achieve skin tightening,” Kenkel says (there have been some burns reported from LAL). And the tumescent anesthetic solution that’s commonly used in regular liposuction results in little to no bruising anyway, Narins says.
Timeline: through thick and thin
Throughout history, women have practiced many forms of girth control — and doctors’ fat-fighting prescriptions have changed with the times.
1926: a woman in France asks her doctor to cut fat out of her knees and calves, but complications result in amputation.
1950s: Surgeons develop a way to inhibit the body’s absorption of food. Weight loss is significant, but so are nutritional deficiencies.
1964: a German surgeon performs lipexeresis, removing fat with a scraping instrument, but the practice never becomes popular.
1966: Gastric-bypass surgery is born. After a small pouch is made in the stomach, only tiny amounts of food can be eaten at once.
1969: a Brazilian surgeon gains media attention for an operation that removes unwanted fat from the buttocks (but leaves long scars).
1970s: Doctors based in Switzerland, Italy, and France experiment with suctioning fat out of the body through incisions, pioneering liposuction.
1985: the advent of tumescent anesthesia, injected under the skin, allows patients to stay awake during liposuction and eases removal of fat.
1997: Liposuction becomes the most popular plastic surgery in the country (it is eventually surpassed by breast augmentation in 2008).
2001: the Lap-Band receives FDA approval. This surgical method is considered safer, although slower, than gastric bypass.
2006: Doctors introduce SmartLipo, a device that melts small areas of fat with a laser before suctioning and is said to minimize bruising.
2007: Clinics offer “lipodissolve” injections containing chemicals to dissolve fat; the FDA states there is no evidence that they work.
Future: UltraShape and LipoSonix, used in other countries to melt fat with ultrasound waves, could gain FDA approval within a few years.
There are several LAL devices, including SmartLipo, SlimLipo, ProLipo, and LipoLite. a new one, LipoEze, can remove large quantities of fat and presents no risk of burns, because the laser is positioned inside the suction tube away from the skin, Narins says.
