Today/YouTube Kevin Smith appeared on NBC's "Today" show on Monday to talk about his weight loss experience and explain how he has been able to shed pounds through adjustments in his diet. In 2010, Smith said he was removed from a Southwest Airlines flight because he was overweight. After suffering a heart attack in February 2018, Smith has now lost 32 pounds and he's feeling "fantastic." This isn't the first time Smith has lost a drastic amount of weight.
