The actor admits he was going through some serious health problems before finally deciding to go vegetarian. He said it was about three years ago he made the commitment and now eats a plant-based diet with lots of protein.

His health wasn’t the only prompt that catapulted him into divorcing his beloved steaks and chicken. He is an animal lover and was ultimately transformed after watching, “Meet Your Meat” and reading “Skinny Bitch” and “Skinny Bastard.”

“I never knew what the process was from that animal to my plate,” Duncan says in a PSA. “Once I looked at an animal like that I cleared out my refrigerator of about $5,000 worth of meat.”

“The best thing about being a vegetarian for me is number one I know I’m not harming any animals.”

At 54 years of age, Duncan’s physique is proof of the statement printed on the ad: “Going vegetarian can prevent–and sometimes reverse–our nation’s biggest killers such as diabetes, obesity, heart disease, cancer and stroke. Muscle your way to better health. Go vegetarian.”

Since going vegetarian, “Big Mike” has shed 35 pounds from his 6-foot-5 frame—and is a lot healthier. He keeps his trimmer, fitter body strong by getting much of his vitamins and nutrientsfrom plants. Instead of packing on protein from an artery-clogging steak, he eats fruits, vegetables, and legumes such as beans, peanuts, and tofu, just like vegetarian athletes Ricky Williams, Mac Danzig, and Daniel Bryan, just to name a few. Duncan says going vegetarian keeps him at a lesser risk of the nation’s biggest killers, including cancer, heart disease, diabetes, and strokes
