(Image source: Jenny Craig) Nestle SA (VTX:NESN) is talking to suitors about selling its diet business Jenny Craig. Nestle acquired Jenny Craig in 2006 for $600 million, but the unit has been struggling to compete with Weight Watchers International, Inc. (NYSE:WTW) and other providers of weight management. The weak economic is also putting a dent on the overall performance of the unit. There is nothing that distinguishes Jenny Craig from Weight Watchers, but Weight Watchers has an appeal with Jennifer Hudson. According to Reuters, Goldman Sachs Group Inc (NYSE:GS) is working on the sale.
