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."

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!"

This @weightwatchers Ambassador is thrilled to announce that I’VE LOST 51 POUNDS! Six months ago from right now, I was in the hospital recovering from a heart attack I’d had the night before.

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! 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.
