"While the Food and Drug Administration (FDA) still must approve the switch, the agency often follows the advice of its experts. If it does, Orlistat (xenical) -- currently sold only by prescription -- could be available over-the-counter (OTC) later this year. But it's important to know that the weight loss that's typical for users of the drug -- 5 to 10 percent of total weight -- will be less than many dieters expect. And many consumers may be put off by the drug's significant gastrointestinal side effects, including flatulence, diarrhea and anal leakage."

"The Frito-Lay report states: "The anal oil leakage symptoms were observed in this study (3 to 9% incidence range above background), as well as other changes in elimination. ... Underwear spotting was statistically significant in one of two low level consumer groups at a 5% incidence above background." Despite those problems, the authors of the report concluded that olestra-containing snacks "should have a high potential for acceptance in the marketplace.""

"GlaxoSmithKline has a tip for people who decide to try Alli, the over-the-counter weight-loss drug it is launching with a multimillion-dollar advertising blitz—keep an extra pair of pants handy. That's because Alli, a lower-dose version of the prescription drug Xenical, could (cue the late-night talk-show hosts) make you soil your pants. But while Alli's most troublesome side effect, anal leakage, is sure to be good for a few laughs, millions of people who are desperate to take off weight may still decide the threat of an accident is worth it."
