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

By Posted on Leave a comment on 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”

    Daily weight check, small calorie cuts, more activity can help young adults prevent weight gain

    By Posted on 2 Comments on Daily weight check, small calorie cuts, more activity can help young adults prevent weight gain

    Losing weight is hard. Keeping it off is harder. It’s definitely doable — we’ve written about successes here — but wouldn’t it be great if young adults could prevent gaining too much weight in the first place? A new multi-year study suggests that with daily weigh-ins and a few small changes, you can.

    The study is among a growing area of research looking at ways to prevent weight gain, and it’s one of the largest randomized controlled studies on the topic to date. Previous research cited in the study suggests that young adults gain about 1.5 pounds per year. Over a couple decades, that adds up. And with two-thirds of US adults now overweight or obese, the research carries important potential for slowing the obesity epidemic. That, in turn, will play a role in cancer prevention. AICR research shows that carrying too much body fat is a cause of 11 cancers, including postmenopausal breast, ovarian and advanced prostate.

    This study built upon prior research about how knowing and tracking your own weight can help with weight control.

    Study researchers split almost 600 young men and women into one of three groups: two interventions and a comparison. Ages ranged from 18 to 35 and about half were overweight. Read more… “Daily weight check, small calorie cuts, more activity can help young adults prevent weight gain”

      Final menu labeling rules released, how they can help cancer prevention

      A year from now when you dine out, you’ll be seeing just how many calories you’re ordering up with that muffin, salad or drink, thanks to the just released final FDA guidance for menu labeling. If you live in places like New York, Philadelphia, Seattle and California, you already see this information, but these new rules – part of the Affordable Health Care Act – are the first national standards for menu labeling.

      bigstock-Eat-healthy-with-this-menu-of--35851439The requirements mean that any restaurant, concession stand, bakery or other eating venue with 20 or more locations will need to post calorie counts on their menu. Other nutrient information, such as saturated fat, carbohydrates, fiber and protein, will need to be available upon request.

      Some national restaurants have already started to do this. Enforcement for everyone begins in May 2016.

      This is an important tool for cancer prevention because Americans eat at least one-third of their meals away from home – usually with more calories than meals at home. With eleven cancers now linked to obesity, this information can help Americans choose healthy, moderate calorie meals more often and help prevent over 130,000 cases of cancer every year in the US.
