WASHINGTON—Citing a “widespread disinterest bordering on contempt” for the program’s most basic aims, Michelle Obama announced Monday she was shutting down “Let’s Move!,” the initiative she created in 2010 to fight childhood obesity. “Though I had hoped ‘Let’s Move!’ would promote healthier habits among America’s children, it turns out our young people simply aren’t interested in moving—at all,” the first lady told reporters. “Seriously, not even a little. When I visit these schools and talk about exercise, most of the kids look back at me with blank stares. And the ones who do attempt to exercise clearly do not like it and stop almost immediately.” Obama added that she expects to achieve far more success with her forthcoming “Fine, Let’s Just Sit Here Stuffing Our Faces Until We Drop Dead!” campaign.
