Washington (CNN) - Turn off the television, drink more water and serve smaller portions to fight childhood obesity, first lady Michelle Obama is urging as she launches a national campaign against childhood obesity.
Mayors, doctors and leaders in sports, entertainment and business will join the first lady as she kicks off the campaign Tuesday at a White House event. Members of President Obama's Cabinet will also be there.
The president is scheduled to sign a memorandum on childhood obesity in the Oval Office, the White House said.
During a speech last month at a Virginia YMCA, the first lady spoke about health issues caused by childhood obesity.
