1. Walking after eating meals can control blood sugar

    Walk away from diabetes

    Preventing diabetes doesn't have to be a big challenge. In fact, it could be as easy as putting one foot in front of the other, because new research shows that walking after eating can help your body deal with the spike in blood sugar that hits after meals.

    You don't have to walk fast, and you don't even have to go very far. All you have to do is wait about 30 minutes after each meal, and then hit the pavement for about 15 minutes at a pace of roughly 3 miles per hour.

    That speed isn't very fast at all.

    But walking after eating can actually help your body control its post-meal blood sugar levels even better than a single 45-minute walk taken at another time of the day, according to a set of experiments on 10 overweight, sedentary, and pre-diabetic seniors.

    The benefits last for up to three hours after that walk, or most of the way to your next meal. But they don't carry over, so if you want to keep getting that benefit, you have to keep walking after eating every day, and after every meal, according to the study published in Diabetes Care.

    That should be easy enough for most people -- but let me throw in a bit of a reality check here as well.

    If you're overweight, sedentary, and pre-diabetic like the seniors in the new study, then that walking after eating is an excellent place to start. But by itself, I don't think it's truly going to keep diabetes at bay.

    To really prevent this disease -- and for overall good health and fitness -- you need more activity than just a 15-minute walk. And don't forget that what's in your meals is even more important than what you do after them -- so along with increasing your activity levels, work on eating better and losing weight.

    I recommend the Mediterranean diet, which can help prevent diabetes and protect the heart without placing too many limits on your food options or leaving you hungry after meals the way other diets will.

  2. Getting fit slashes risk of cancer and heart disease

    How jumping jacks could save your life

    Time to get moving, sir -- because getting fit today could protect you from some of the leading cancers in men for years or even decades down the road.

    One new study finds that getting fit in your 40s, 50s, or 60s could slash your risk of lung cancer by 68 percent and colon cancer by 38 percent -- not just now, and not just for a little while... but for a whopping 25 years.

    That's a quarter of a century of protection from just a single healthy habit.
    And if you do happen to get colon, lung or prostate cancer, getting fit can slash your risk of dying of the diseases, according to the new study of 17,000 men.

    Of course, there are different levels of fitness and different ways to measure it. And, let's face it, not everyone's an athlete.

    And if that's you, don't worry. There's an easy way to get most of the benefits even if you're badly out of shape -- and you don't have to train like you're competing for a spot in the Olympics.

    Start by hopping on a treadmill and seeing how long you can go at full speed. Then, get to work on improving that time and getting fit.

    If you can add just three more minutes to your time, your risk of death from cancer will drop by 14 percent and your risk of death from heart disease will plunge by a quarter, according to the researchers.

    And if you can keep improving on your time, you can bring those risks down even further.

    It's like winning the battle against disease, three minutes at a time.

    (Did you know that exercise isn't just good for your body it's good for your brain too? It could be the key to slowing down or reversing the ravages of dementia. Click here to get all the details.)

    If you're overweight, don't let that stop you -- the study finds that obese men can get all the benefits of fitness even if they remain obese. (On the other hand, if you really work at getting fit, you will almost certainly lose the extra weight anyway.)

    And if you're slim and trim, don't rest on your bottom, keep getting fit -- because the study presented at a meeting of the American Society of Clinical Oncology finds normal-weight men with low fitness have the same risks of cancer and cancer death as obese men with low fitness.

    I'm not done with exercise news yet. You could be undoing all your hard work without even knowing it -- especially if you're taking this common drug.

  8. Wrong approach to obesity

    At least we're not getting fatter. The newest obesity numbers are in and, well, this is what passes for victory these days: Americans have had roughly the same rate of obesity for much of the past decade, with a little more than a third of us in need of plus-size clothing.
  9. More meals, less weight
