5 Things You Can Do to Combat Aging
"Positively Ageless," huh? Well, the author is the nutritionist for "The Biggest Loser." And while, admittedly, we have never seen that show, most everyone else in the world has. Plus, the book is published by Rodale, which puts out such faves as Prevention and Men's Health.

So Cheryl Forberg, tell us what you know. Tell us how to reverse aging at the cellular level, lower our risk of age-related illnesses and feel and look our best for life.

Narrow it down to five though, wouldja, hon? Then we can all go out and buy the book ($21.95) to find the rest.

1. Get energetic! Fill up on fiber:

Who feels energetic when they can't, um, go? Shoot for 25 grams a day. Fuel up with fluids: Your cells depend on fluids to bring them nutrients and oxygen.

2. Make even one change.

Forberg suggests these: Stop smoking. Measure portions. Invest in nonstick pans. Skip the white stuff (sugar and flour, to name but two). Keep a basket of fruit in plain sight and don't resist when you walk by.

3. Get tested.

Have a colon screening. A fasting blood-sugar test. A mammogram. A thyroid test. An STD test (yes, even you).

4. Make the most of, or avoid, age-related hair changes.

Make sure your diet includes protein and iron, since lack thereof can contribute to hair loss. Find a hairdresser who can give you an age-appropriate style - and no, that doesn't necessarily mean a blue helmet that needs to be re-coiffed weekly.

5. Get enough sleep.

Keep a regular sleep schedule, even on weekends. Relax before bedtime; don't watch Rambo movies or pay bills. Finish dinner at least two hours before turning in, thus avoiding heartburn.
