Mayor Rob Ford postponed and then cancelled his weekly weigh-in on Monday.

“Yes we are doing the weigh-in today — but the time has been moved till noon,” he wrote on Twitter in the morning. Later, he wrote, “Very busy day today — the weekly weigh-in has been cancelled for today.”

Ford’s weight-loss effort has stalled in recent weeks. He weighed 308 pounds last week, down from 330 when he began his diet regimen but the same as he weighed a month prior. He wants to weigh 280 pounds by mid-June.
