The evidence is stronger than ever that being overweight or obese increases the risk for kidney cancer, according to a report we released today. It’s the key finding in the latest update from our ongoing systematic review of the global research, the Continuous Update Project (CUP).
Today’s report reaffirms the conclusion of our previous report, making kidney one of ten cancers now strongly associated with overweight and obesity. You can read the key findings here.
Among those findings, you’ll also find a new conclusion with alcohol. Here’s what we can say about alcohol and kidney cancer: it’s complicated.
Alcohol is known to be a potent carcinogen, and has been definitely linked in previous reports from AICR and WCRF International to greater risk of cancer of the mouth, pharynx and larynx, esophagus, liver, colorectum, and breast. This is why AICR recommends that if people choose to drink at all, they limit their consumption to 1 drink/day for women, and 2 drinks/day for men.
But when our CUP panel examined recent evidence from 8 studies, they found that moderate amounts of alcohol (about two drinks per day) were associated with lower risk for kidney cancer. Continue reading
Does the old weight loss advice to drink water before a meal really help? A new study says it just might. Finding simple, low-cost and effective strategies for weight loss could mean lower cancer risk for thousands of Americans every year because too much body fat is a cause of ten cancers, including colorectal and post-menopausal breast.
The 12 week study, published in Obesity, randomized 84 obese adults into two groups: one group was told to drink 2 cups of water 30 minutes before meals and the other to imagine their stomachs were full 30 minutes before their meals. All participants were given a half hour session on weight management strategies and all received a follow-up phone call later to gauge how closely they were following their plan – either water drinking or stomach imagining. The researchers also sent them text messages reminders and participants completed questionnaires about compliance throughout the study.
Both groups lost weight, but the water drinking group lost, on average, about 3 pounds more than those who imagined full stomachs. About one-third of the water drinkers did so 3 times per day. Even more impressive is that they lost an average of 8 pounds more than those who reported drinking water 0-1 times per day before meals. Continue reading
For those working to lose weight, hopping on that bathroom scale daily, having goals and charting your progress may be simple but effective ways to bump up weight loss, suggests a new study published today.
The study, published in the Journal of Obesity, adds to a body of research finding that dieters who track their weight have better success at both weight loss and maintenance. And for lower cancer risk, weight is important. Being overweight and obese is a cause of ten cancers, including postmenopausal breast, colorectal and liver. AICR’s top Recommendation for Cancer Prevention is for people to stay a healthy weight.
This study was held over two years and it started with approximately 150 participants all learning the same evidence-based strategies for weight loss. Everyone was encouraged to make small healthy changes but they weren’t given a specific diet or exercise plan.
The men and women were then divided into two groups. One group was given a scale and asked to weigh themselves daily, preferably in the morning, and then enter their weight on a (password-protected) website. They were directed to aim for 10% weight loss that first year then maintain it the second year. The website gave each person a chart that tracked their progress along with visualization of goal weights. The chart showed trends, having a line appear 1% below the person’s current weight for a new target weight. (After maintaining that target weight for 8 days, the green line lowered another 1% on the chart.)
