The Ozempic craze shows no signs of slowing. Demand for the drug, popularly used for weight loss, is so monumental that it is already changing the diet industry and spurring a “marketing bonanza” among the dozens of telehealth start-ups that now prescribe it. A highly public ad campaign from one start-up, Ro, banks on the drug’s simple premise: “A weekly shot to lose weight.”
Never before has a weight-loss treatment been hyped this way and been able to deliver on its promise. Ozempic itself is technically a diabetes drug, but its active ingredient, semaglutide, has been approved by the FDA for weight loss under the brand name Wegovy, and can reduce a person’s body weight by up to 20 percent through a weekly injection. An even more powerful drug, known as tirzepatide, or Mounjaro, may soon be approved for weight loss, and a host of new medications are coming down the pipeline. All signs suggest that America is on the verge of a weight-loss revolution.
But for people with obesity, semaglutide isn’t even the most effective weight-loss treatment around—not even close. Bariatric surgery, which has existed for many decades, is still significantly more potent. This class of procedures, which, broadly speaking, reconfigure the digestive system so people feel less hungry and more full, is considered to be the “gold standard” for treating obesity, Holly Lofton, an obesity-medicine physician at NYU, told me. Most people experience weight loss of 50 percent and, with one procedure, up to 80 percent, according to the Cleveland Clinic.
Despite the impressive abilities of the new crop of weight-loss drugs—and bold assertions that such drugs could someday replace surgery outright—several doctors told me that surgery will likely continue to be the top-line treatment for obesity, even as the medications improve. People may seek out treatment with the new drugs because they’re so popular, but “long term, there will be an increase in surgery,” Shauna…
