1 Hour: Amount Women Should Exercise to Prevent Weight Gain
We all know that regular physical activity has a variety of health benefits and can help with weight loss. But wouldn't it be nice to know how much you need to exercise daily in order to prevent weight problems in the first place? According to a new study, an hour of moderate-intensity exercise each day could be the magic number.
The study, published in the Journal of the American Medical Association, found that one hour of moderate-intensity exercise each day was enough to help middle age and older women maintain a normal weight. And if they were able to exercise vigorously, just 30 minutes each day was enough to help normal-weight women maintain their weight. This also assumed the women had a normal, healthy diet.
The study followed over 34,000 women for 13 years. Their average age was 54. Overall, participants gained an average of 5.7 pounds over the 13 years, which is considered normal for the general population. But the women who exercised for 60 minutes daily tended to gain fewer pounds than average, compared to those who exercised less.
What kinds of activities count? Moderate-intensity activities would include things like brisk walking, playing with kids, household chores, and casual biking. Vigorous-intensity activities would include things like running, swimming laps, high impact aerobics, and basketball. And if you're not able to do a full 60 minutes of exercise each day, don't despair. You can still get health benefits from less because some is definitely better than none.
The results of this study did not apply to overweight and obese individuals. Numerous studies have looked at how exercise can help people lose weight, but this is one of the few to look at preventing weight-gain over time in normal-weight individuals.
What do you think? If you're someone who is trying to maintain your weight, what amount of exercise works best for you?

~~~An hour a day of moderate-intensity exercise will prevent weight gain in normal-weight women, middle age and older, according to a new study.
"'Moderate intensity' means brisk walking, casual bicycling, ballroom dancing, playing with the grandchildren," said Dr. I-Min Lee, lead author of the study, which is published in the March 24/31 issue of the Journal of the American Medical Association.~~~ - 4/8/2010 6:26:29 AM
yes, i change up my exercises, classes, etc.but i'm old, i want a senior citizen discount!! there is no way i'll work out an hour 7 days a wk; i'd rather drink water one day/wk.
not to sound ugly, but, seriously... HOW do you workout an hour a day w/out being burned out! i can't find the motivation--good for you if you can!
findings like that do NOT encourage ppl to START exercising... - 4/7/2010 4:27:02 PM
Which only leads me to say "We need to make US a priority girls!!!" - 4/7/2010 2:49:33 PM

Is this the kind of results they mean? ;-)
[I certainly cannot do anywhere near as much exercise now as then. I am now post-menopausal, but I sure changed my program ... I'd even gone pescetarian for 9 months, now I am somewhat omnivorous, but I am always eating rabbit food ... !] - 4/7/2010 9:57:35 AM
Congratulations to those of you who already have made a workout a non-negotiable part of your day! - 4/7/2010 9:41:32 AM
Honestly, I think calling "household chores" a workout is borderline LYING. Unless you're doing a major spring cleaning and scrubbing the floors on your hands and knees, cleaning your house is NOT workout. Walking burns so few calories, it's only a workout if you sustain it for more than 30 minutes, maintaining a speed of 3.5mph. (Of course, none of this quite applies to those who are obese/new to exercise, but for most folks, this holds true). - 4/7/2010 7:10:40 AM
My family eats typical (smaller) Asian portion sizes and foods (home cooked, not that high-fat-high-sodium restaurant junk), almost never watches TV (which is an "exercise in sitting"), and we regularly walk our dogs (about 20 min at a time), walk or bike to nearby stores (weather permitting), etc. but not 60 min a day or even 7 days a week. My family is not overweight. (And I am "not so young" - I have a kid in college.)
Additionally, Europeans whom I know walk a LOT more than Americans do and take more (very handy) public transportation - and they are as thin as sticks: probably because of this, and likely also because of a different daily diet and smaller portions than most Americans.
However, if exercise helps people balance what they eat to maintain their weight- more power to them!
Exercise is good for you, and will help you live longer and retain body mobility into old age, factors which should not be ignored despite the more-trumpeted "need to keep weight down!" issues. - 4/7/2010 5:43:43 AM
