Getting Americans off the couch and onto their feet could save an estimated 200,000 lives a year, says the surgeon general. Yet most of us are either sedentary or only minimally active. Confusion may keep many couch potatoes from getting into shape. People still ask questions like: How often should I exercise? (The more, the better, but at least 30 minutes nearly every day.) Does it have to be 30 minutes straight? (No, shorter bouts are fine.) Do I need to go to the gym? (No, walking, dancing, lawn mowing, and gardening are fine, if they're intense enough.) Still, in a world where infomercials, magazines, videos, and friends may give conflicting advice, misunderstanding abounds. To read more click here.

A Complete Guide to Keeping Your Metabolism Strong and Healthy
Learn everything you need to know to keep your metabolism in check.Every cell in your body requires energy to function―whether it’s delivering nutrients to your brain, pumping oxygen from your lungs to your muscles during a long power walk, or producing infection-fighting white blood cells deep in your bone marrow. Metabolism is the name for the system by which the body converts the calories in food to energy (blood sugar) to perform these and many other functions.
Many factors contribute to your metabolism, including heredity. You’re born with an internal speedometer that regulates your base metabolic rate (BMR), the pace at which your body uses energy when you’re at rest. BMR accounts for approximately 60 percent of the total energy an average person expends in a day. (The rest is used in digestion, exercise, and non-exercise activities―showering, chopping vegetables, or fidgeting.) “We are not sure what makes people different in terms of metabolism; the genes determining that have yet to be identified, but it’s being explored,” says Gary Miller, PhD, associate professor of health and exercise science at Wake Forest University in Winston-Salem, North Carolina.

Obesity-Cancer Link Unknown to Many Women
By Anne Harding
NEW YORK (Reuters Health) - Many women don't know that obesity increases their risk of several types of cancer, a new survey published in the journal Obstetrics & Gynecology shows.
Women's lack of knowledge about excess weight and the most common gynecologic malignancy, endometrial cancer, is particularly worrying, Dr. Pamela T. Soliman of M. D. Anderson Cancer Center in Houston and her colleagues say. "We need to be doing a better job of educating our patients," Soliman told Reuters Health.
Women who were overweight were four times more likely to develop cancer of the uterine lining, Soliman and her team note in their report, while obesity boosts the risk by six-fold. Obese women also are at greater risk of breast and colon cancer. Excess weight also increases mortality from many cancers, with the strongest association seen for endometrial cancer; heavy women are 6.25 times more likely to die from the disease.
To investigate awareness of the obesity-cancer link, Soliman and her colleagues surveyed 1,545 women, 28 percent of whom were normal weight. Another 24 percent were overweight, while 45 percent were obese. Ninety-one percent of the study participants had health insurance.
Just 42 percent knew that obesity increased their risk of endometrial cancer, while 53 percent knew that colon cancer is associated with obesity and 54 percent were aware that excess weight increases breast cancer risk.
The women in the current study were fairly well educated, with most having a college or professional degree, Soliman noted, and the great majority had health insurance. "Even patients who are routinely seeing their physician weren't aware that obesity increases their risk," she said.
Vaginal bleeding is a key symptom of endometrial cancer in post-menopausal women, while bleeding between periods can be a sign of the disease in women who are still menstruating, Soliman said. Seventy-five percent of endometrial cancer cases are caught early, and early-stage disease can typically be cured with surgery, she added. "It's a relatively curable disease and that's why it's so important if women have symptoms to seek care."
