This was a reply to something else, but they made a good argument that I wasn't necessarily looking at the data they were talking about. But I'll leave this here anyway, as it's something to think about (that maybe the obesity epidemic, if it did in fact occur, is at least leveling out now).
"Among Canadian youth (aged 12 to 17), the rates of overweight and obesity between 2005 and 2012 are largely unchanged (2003 data were not available)."
"The very latest CDC study confirmed that in recent years the adult obesity rate has plateaued, at worst."
