Study: Lose weight through diet alone, or with exercise, cut cancer- promoting substances

AICR’s evidence shows that having too much body fat increases risk for eleven cancers. But researchers are looking at whether losing weight, once overweight, would lead to lower risk for these cancers. Now a new study from researchers at Fred Hutchinson Cancer Research Center shows how weight loss – through diet alone or diet and exercise – might change pro-cancer substances in the body.
The 12-month controlled trial of 439 healthy, postmenopausal women with overweight/obesity included 4 randomized groups: calorie restriction diet; moderate activity (goal of 3.75 hours per week), diet and exercise, and no intervention. Researchers wanted to see if these lifestyle changes would affect four substances in the body (biomarkers) that influence formation of blood vessels needed for tumor growth. Fat cell growth also requires a greater blood supply, so these biomarkers are also associated with increasing fat tissue.

After 12 months, women in the exercise group lost 2.4% of their body weight; diet only reduced by 8.5% and those exercising and dieting lost 10.8% of their weight. And the more they lost, the more their biomarkers were reduced. Read more… “Study: Lose weight through diet alone, or with exercise, cut cancer- promoting substances”

    Sitting at your standing desk? Workplace study shows strategies that get you up

    How much time do you spend sitting? If you work in an office, chances are it’s an average of around 11 hours a day and that most of your time spent sitting happens at work.

    By now, you’ve probably heard that spending too much time sitting isn’t great for your health. Too much sedentary time may increase the risk of heart disease, diabetes, cancer, and overall mortality. Making an effort to move more throughout the day may lower your cancer risk and improve your overall health.

    In order to help their employees sit less, some employers have installed special desks that can be raised or lowered so that workers have the option to sit or stand. But in order for sit-stand desks to work, employees must use them.

    A recent study published in the International Journal of Epidemiology suggests strategies that offices can use to make sure investments in sit-stand desks pay off. Read more… “Sitting at your standing desk? Workplace study shows strategies that get you up”

      School’s out for the summer and kids are ready to play! This is a great time to make healthy habits part of your family’s summer plans. Give your kids a start for lifelong cancer protection by helping them be active. For adults, AICR research shows that moving for at least 30 minutes daily lowers the risk for post-menopausal breast, colorectal, and endometrial cancers.

      To find out how Americans will be getting active, the National Recreation and Park Association asked about favorite summer outdoor activities in a recent survey. Half of those surveyed said that going for a walk or a hike is one of their favorites. Walking and hiking are great ways to explore nature in your local park, on a National Park trail, or to find a new shop in your neighborhood. At the same time you’ll boost fitness, strengthen muscles and build endurance.
