Carson lost 60 pounds at age 60.

Looking for more support and motivation in your weight-loss endeavours this summer?

Then sign up for the second annual Fat-to-Fit Weight Loss Challenge.

The online program, launched by the AARP (formerly known as the American Association of Retired Persons), challenges Americans – and Canadians – “to make positive, permanent life changes to improve their health,” according to a press release.

Fitness expert and author Carole Carson, who lost more than 60 pounds at age 60, will offer her expertise through the Fat-to-Fit online community.

“I’m living proof that you’re never too old to get fit,” said Carson. “Unlike diets and other weight-loss programs, Fat-to-Fit is intended to help people make permanent, positive life changes – not just drop 10 pounds and then return to their former lifestyles. Our hope is to help people break the diet-relapse cycle for good.”

The 11-week challenge runs through Sept. 6, with plenty of fabulous prizes.

Official rules and details are available at www.aarp.org/fat2fit (don’t forget to check out the video in the middle of the page).
