Biggest Loser Health Tips

Mark wasn't the only one in his family to take the weight loss challenge. His younger brother Jay was also on the show! "One of the most special things about this experience for me is that I got to share it with somebody I spent my entire life around," Mark says.

Jay started the competition weighing 293 pounds. Now, he tips the scales 87 pounds lighter! Jay credits the show for strengthening his emotional bond with Mark. After the show ended, Jay says their brotherly competition motivated him to continue his journey. "Even today, I know he's in the gym working out, and it makes me want to work out just as hard and stay healthy," Jay says.
