3 Steps to a Fitter, Slimmer, Younger You
Most of us assume aging is as inevitable as a Bachelor breakup. But get this: “What we think of as growing old is just decay at a cellular level. It’s the molecular dry rot of our modern lifestyles. And it’s optional!” says Henry S. Lodge, M.D., associate clinical professor of medicine at Columbia University and a SELF contributing expert. The science: Your cells constantly regenerate. Taste bud cells turn over every few hours; muscle cells refresh every 90 days. On average, you renew about 1 percent of the cells in your body daily, Dr. Lodge explains. Those cells come in either stronger (read: younger!) or weaker (older) than their predecessors did, based on the chemical signals they receive. Work out and your body hears, Let’s get a little bit younger. Sit on your butt and the message is, Gray hair and wrinkles, activate! And it’s not only your body that benefits. With regular activity, new tissue grows in the cognitive and emotional areas of your brain, keeping you on top of your mental game. Exercise is the fountain of youth. Don’t simply toss in a coin and wish for a younger, fitter body. Try our three-step plan guaranteed to put time on your side.
