First Lady Michelle Obama will speak in Lisner Auditorium March 8 as part of a childhood obesity prevention summit.

Obama, honorary chair of the nonprofit Partnership for a Healthier America, will keynote the two-day conference and give a talk on combating childhood obesity before more than 1,000 guests.

The summit, from March 6 through March 8, will feature speakers such as the editor of Cooking Light magazine, president of the National Restaurant Association and an epidemiologist for the Centers for Disease Control and Prevention. The organization’s honorary vice chairs Mayor Cory Booker of Newark, N.J., and former Republican Senate majority leader Bill Frist will also be in attendance.

The first lady has championed healthy living during her time in the White House, launching the ambitious Let’s Move campaign in 2010 and promising to eradicate childhood obesity within a generation.

Obama was also the keynote speaker at the organization’s 2011 conference.
