WW International Inc. has filed for bankruptcy to implement a creditor-backed plan that would cut about $1.15 billion in debt from its balance sheet. The company has struggled to compete with diet pills like Ozempic and has found it hard to convince customers that its programs are still worth their time in the face of those drugs. Weight Watchers reported a 9.7% drop in revenue in the first quarter of this year, a 14.2% drop in subscribers at the end of the period, and a net loss of $72.6 million.
