Ever wonder how much harm your lifestyle is doing to your body? Do you ever look in the mirror and think, "What happened?" Do you look older than you should and is it possible to repair the damage and extend your life? Turn Back Your Body Clock is a new eight-part series hosted by tell-it-like-it-is physician, Dr. Una Coales. On the show, Dr. Coales meets with eight different people who have let healthy habits slide. After a full physical examination, Dr. Coales gives them a frank assessment of their health, including an estimate of when they'll die. It's a shocking wake-up call for those who have been blind to their physical state.

Dr. Coales doesn't believe in mincing her words. She sees people every day who are killing themselves with simple overindulgence, and she's had enough of it! She's happy to be cruel if she can change someone's life. On Turn Back Your Body Clock, she berates people for their expanded waist-lines and sagging flesh, lists their bad habits, and shows them images of their own damaged internal organs.

While much of the aging process and risk of disease is down to genetics, how long we live is also influenced by what we eat, what we drink, how we exercise, and everyday lifestyle choices. Combining cutting edge medical analysis with personal examination, the show reveals the effect unhealthy living can have on premature aging, both inside and out, and how it can knock years off your life.

The idea of a ticking body clock may sound morbid, but there are changes that you can make that will help you to live longer and be happier while you do it. Dr. Coales and trainer Tim Bean put eight people on an eight-week plan, improving fitness, melting fat, eliminating fatigue, increasing fertility, and, most importantly, adding years to their lives. But will everyone be able to adapt to the new regime?
