For nearly 30 years, 'This American Life' producer Susan Burton kept her binge eating disorder a secret. "As long as I was bingeing, I didn't have to think. I didn't have to think about any loss or pain or wanting or yearning." Burton also had anorexia, though that was harder to hide. She talks about her difficult relationship with food and work toward recovery. Burton's memoir is 'Empty.' Ken Tucker reviews Lady Gaga's 'Chromatica' and Carly Rae Jepsen's 'Dedicated Side B.' And book critic Maureen Corrigan reviews the memoir 'All The Way to Tigers' by Mary Morris.
