Celebrities who have lost weight

Actor Tom Arnold debuted an 89-pound lighter body in People magazine's 'Half Their Size' issue in January 2014. The actor contributes his weight loss to his newborn son, Jax, who he says he wanted to be able to live as long as he could for.  'The moment I saw [Jax] I realized he deserves the best,' Arnold said. 'I have tons more energy to play with my son.'
