If you’re debating whether to go the extreme, quick-results road with your New Year’s Resolution (which started yesterday, remember) or adopt a healthy, lifelong lifestyle, check out a New York Times story this week on past contestants on NBC’s “The Biggest Loser.” As you might expect, the long-term impact for many of the contestants over the past eight years has not been good, starting with first season winner Ryan C.

Good insight into the show and why strategies that cause you to lose 15 pounds a week or more not only don’t work in the long run, they can threaten your life.
