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.
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
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.
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
We talk a lot about food and eating here because research shows it matters for cancer prevention. Now a study that quantifies the benefits of home cooking finds that if you frequently cook dinner at home you’re more likely to eat fewer calories, both at home and eating out, compared to those who seldom cook.
The study was published in Public Health Nutrition yesterday.
People who cooked dinner the most, at least six nights a week, were eating 137 fewer calories per day on average compared to those cooking dinner only once a week or not at all.
Study authors used data from almost 9,600 adult participants of the government National Health and Nutrition Examination Survey. Participants answered questions about how many times they cooked during the past week and what they ate during the past 24 hours, along with questions such as about dieting.
The more people cooked, the less calories they ate. In 8% of adults’ homes, someone was cooking dinner once or less a week. These people were eating on average 2,301 calories a day. Almost half of households – 48% – were cooking dinner six to seven times a Continue reading
