Trying to lose weight in 2013? Now's a perfect time to focus on recharging your metabolism — especially if you're over 40. At this age, certain hormones begin dipping and a healthy diet alone isn't enough to keep the extra weight off. These days we're also constantly exposed to toxins, the food we buy is losing its nutrients; and we're less active than we once were.

It IS possible, however, to live a clean, healthy, and long life — with a slim body, even after 40! The following lifestyle changes can help you reboot your system and achieve the body you want.
