Kevin Smith drops 51 pounds, now at his lowest weight since high school

Actor, comedian, author, filmmaker and podcaster Kevin Smith had a heart attack six months ago.

Kevin Smith may have to change his "Clerks" character's name from Silent Bob to Skinny Bob.

Soon after suffering a major heart attack in February, the director became a Weight Watchers ambassador. He has shed 51 pounds by switching to a vegan diet.

» Kevin Smith says he survived 'massive heart attack' 

"Six months ago from right now, I was in the hospital recovering from a heart attack I'd had the night before. When I went to my Doctor a week later, she told me, 'The best thing you can do for yourself now is to lose 50 pounds.' Half a year later, I can report that I followed Doctor's orders: I started at 256 and now I weigh 205. This is the lightest I've been since high school! My hope now is I can slowly lose another 10 with #weightwatchers and get down to my birth weight of 195! But for now, I'm ecstatic to have reached this chunky milestone!"

Smith credited magician Penn Jillette, who dropped more than 100 pounds after high blood pressure landed him in the hospital in 2014, for introducing him to Ray Cronise's  Just Sides diet, or to use his own words, "getting me started with (this) potato famine."

He also gave a shout-out to his vegan daughter, Harley Quinn. He called her "the little vegan astronaut who explored this meatless/milkless galaxy ahead of me."

He continued,  "Since I never wanted to see the inside of a hospital ever again, I simply copied the Kid. So this wasn't a diet: these results came from a total lifestyle change of eating solely plant-based foods (which is tough because I hate vegetables)."

Finally, he thanked his fans for their moral support.

"But mostly, I wanna thank all of you as well - for the kind and encouraging words along the way. Never underestimate the power of positive feedback: you folks telling me I looked better or healthier helped me stick with it. An encouraging word can really make a difference in someone's life and your compliments kept me going! And just look where I went!"
