The Biggest Loser’s Colby Can’t Believe His 90-Day Sugar Intake: ‘That’s Crazy!’

Pour some sugar on me! The Biggest Loser's two-hour Monday, February 15, episode includes Colby Wright learning exactly how much of the sweet stuff he has consumed from beverages in the past three months, as seen in Us Weekly's exclusive sneak peek.

In the clip, host Bob Harper and Dr. Robert Huizenga reflect on how much progress the Georgia-based car salesman has made by highlighting the fact that he was taking in a colossal amount of sugar through liquids before he started his stint on the NBC weight-loss series.

"I remember when we were all together with Dr. H, how emotional you were, how you just felt like, 'Wow, I'm at the end of my rope,'" Harper says.

Huizenga then holds up a covered dish to reveal how much sugar Colby has had since competing on the series.
