TV personality Al Roker talks to USA TODAY's Craig Wilson about his new book "Never Goin Back", losing weight and shares tips about weight-loss with readers.

TV personality Al Roker was having major issues with his weight until finally he was able to bring his weight down from 340 pounds to 200 pounds. The "weatherman" now shares his weight loss journey with viewers in his new book "Never Goin Back". During a telephonic interview with USA TODAY's Craig Wilson, Roker reveals how he managed to lose weight, how people go wrong by dieting and other ways to stay in shape.

Firstly, Roker reveals that there's no short cut to losing weight. It can't be just a diet or just exercising. Losing weight requires changing one's lifestyles, states Roker.

"There is no quick fix. At the end of the day, you still have to do the work to maintain your weight. It can't be a diet. You have to change your life," USA Today quoted him saying.

Roker also reveals that the main reason for him weight 340 pounds was "mindless eating." He admits he ate all the time, even when he was engaged in other activities. And then, came the phase when Roker stated "yo-yoying" between diets.

"Yes. I'd probably say my biggest yo-yo was when I was finishing up my senior year of college. I lost about 100 pounds and within a year gained it all back. I'd say I yo-yoed from 20 years old to about 10 years ago," says Roker.

There was a time when Roker weight 190 pounds but later gained another 40 pounds. When asked about what happened, he replied, "I stabilized at about 200 for almost eight years, then my Mom got sick. I was driving back and forth from Long Island every day after the show. I spent a few hours in the car and reverted back to those old bad habits. I ate. I had resisted all those bad habits for a long time, then I was thrown for a loop."

Roker also says that when someone is in shape, people only see the fit person, but not the hard work he or she puts in to stay in shape.  Roker also admits the biggest advantage of being "skinny" is the fact that it's more fun to go shopping then.
