New Study: A 20 Minute Daily Walk for a Longer Life

Today, a new study found that replacing even a small amount of that sedentary time with some physical activity could reduce early death for people of all weights and waist sizes. A growing body of research is linking sedentary behavior to cancer risk.make-time-break-time

The new analysis, published in American Journal of Clinical Nutrition, used data from over 334,000 people in the European Prospective Investigation into Cancer Nutrition (EPIC) study to determine if overweight, obesity or large waist size would affect whether reducing sedentary behavior improves survival.

The investigators compared rates of mortality over twelve years, between four levels of physical activity (inactive, moderately inactive, moderately active and active) and categorized by BMI and waist size. Continue reading


Apps, Diets and More: Steps for Weight Loss Success

In today’s CRU, we highlighted a new study looking at whether using a phone app helped overweight people lose weight. In this study, overall the phone app did not make a difference for most people, but the few participants who actually used it did lose weight. Finding ways to help people lose weight successfully is important because excess body fatness now links to 9 cancers, including post-menopausal breast, endometrial and advanced prostate.A blank notebook, green apple, pencil, measuring tape on wooden

For me there are 3 important takeaways from this study – the questions is not whether apps work for weight loss – but what does it really take for successful and sustained weight loss.

1.    Be ready to commit.
Wanting to lose weight is an important first step, but not enough. Start by developing your specific goal, identify the barriers, and understand that you will be working hard to make changes that will last. If you decide you aren’t ready for full commitment, you might choose one small change to improve health – like adding 5-10 minutes of walking to your day. That, by itself, won’t lead to weight loss, but that may help you be confident in your ability to begin to make changes. Continue reading


Study: Almost Half a Million Cancers Worldwide Due to Obesity

Almost half a million cancer cases worldwide are due to the rising rates of overweight and obesity, making many of the most common cancers potentially avoidable, says a new study published in The Lancet Oncology.canstockphoto12101428

The study was funded in part by the World Cancer Research Fund (WCRF) International, which AICR is a member. AICR and WCRF now estimate that approximately 122,000 cases of cancers in the US are due to overweight and obesity.

Researchers in The Lancet study calculated that  481,000 – 3.6% – of all new cancer cases in adults worldwide were attributable to high BMI in 2012, the latest global data available.

Obesity-related cancers are more likely to affect women than men, largely due to endometrial and post-menopausal breast cancers, according to the study. In men, excess weight was responsible for 1.9% or 136,000 new cancers in 2012, and in women it was 5.4% or 345,000 new cases. Continue reading
