The Biggest Loser winner John Rhode is still basking in the glory from being crowned the season 12 winner on Tuesday, but he isn't about to ditch his diet plan for the holidays, even though it is going to be a tough challenge.

"It will be very difficult to maintain my regimen over the holidays," Rhode told RadarOnline.com in an exclusive interview. "I plan on getting my workouts done early in the morning."

Despite losing a whopping 220 pounds - adding up to 49.44 percent of his body weight - the reality show winner still worries about falling off the wagon and regaining the weight, so he doesn't plan to indulge in all the traditional calorie-laden holiday treats.
