After His Heart Attack, Kevin Smith Has Lost 51 Pounds on This Controversial Diet

Film director Kevin Smith shared a picture that showed off his results from the so-called "mono diet."

By Tamara Palmer

Kevin Smith is celebrating a milestone achievement just six months after suffering a heart attack. The film director has lost 51 pounds, and is now a Weight Watchers ambassador — but he kickstarted the weight loss by following a regimen known as the "mono diet," whose followers eat just one thing.

Smith announced that he achieved his weight-loss feat by eating only potatoes for the first few weeks on the controversial mono diet — which is the same one Penn Jillette used on his 100-pound weight loss journey that he documented in his book, Presto. Experts warn that mono diets can starve a person of their needed nutrients and can cause unhealthy relationships with food.

Still, Kevin says he used this path successfully a building block to his weight loss.

"This @weightwatchers Ambassador is thrilled to announce that I’VE LOST 51 POUNDS!" he wrote on Instagram. "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!"

But for now, I’m ecstatic to have reached this chunky milestone! I wanna thank #pennjillette for his book #presto, @raycronise for getting me started with his potato famine, and the good folks at #weightwatchers for their app-based program that made it easy to keep track of and control my eating! And I also wanna thank my kid @harleyquinnsmith - the little vegan astronaut who explored this meatless/milkless galaxy ahead of me, leading by example. 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). 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! #KevinSmith #WWambassador #WWFreestyle #WWFamily #WWBros #weightlosstransformation #weightloss #WWCommunity #ad *People following the Weight Watchers program can expect to lose 1-2lbs per week.

Kevin stresses that although he started with the mono philosophy of eating just potatoes, he didn't ultimately go on what he thinks of as a "diet," since he's made permanent lifestyle changes.

"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)," he wrote. "But mostly, I wanna thank all of you as well - for the kind and encouraging words along the way.
