Take Bob Harper’s 24-Hour Vegan Challenge

As one of America’s toughest trainers, The Biggest Loser‘s Bob Harper is hardcore. He’s taken 100 pounds off a man in a mere seven weeks (remember Rudy?), breaks contestants down and builds them back up during Last Chance Workouts, and gives us the skinny with his Trainer Tips on NBC. Now he’s focused on challenging the country to a 24-hour vegan cleanse.

Bob’s latest tweet reads, “Your Challenge today is to go the next 24 hours, starting now eliminating ALL animal products. Good for your heart AND the environment!!”

Go vegan? But how? Well, in the famed words of Bob himself, “Just stop talking and do it!” Or, you know, a vegetarian/vegan starter kit works just as well.
