How long did it take you to eat breakfast? What about dinner? If you want to cut calories without being hungry, a new review of the research suggests that eating that meal a little slower may help you do just that.
Dietitians, and mothers everywhere, have long suggested that people should eat slower. A few observational studies have also noted that heavier people eat more quickly than those who are leaner.
But this analysis focused only on experimental studies. It adds to the evidence that eating slower may help people get to a healthy weight, without being hungry. And being at a healthy weight is one of the most important ways to reduce cancer risk, given that overweight and obesity link to increased risk of eight cancers.
For this analysis, researchers found 22 studies that each manipulated how fast people ate, then measured how much they ate. Most of the studies randomly assigned people to an eating-rate group. Continue reading
Like most American women (and men), most breast cancer survivors may also not be exercising enough to reap its many health benefits, suggests a new study. Yet it’s African American survivors who are even less likely to meet the activity recommendations compared to white women.
The study was published today in Cancer. It’s important because a lot of research has linked regular physical activity among survivors to to better health and longer lives.
AICR recommends that survivors follow the same activity recommendations as for prevention. Here’s a few examples of studies that have found how activity benefits survivors.
In this study, about 1,700 women diagnosed with breast cancer reported their activity habits both before their diagnosis and six months afterwards. The women ranged in age from 20 to 74, and about half were African American. Researchers converted the women’s activity habits into a common unit of measure: metabolic equivalent hours (METs).
Six months after diagnosis, 59 percent of all the patients reported being less active. Only about one-third of women reported they were active at least 150 minutes per week compared to 60 percent before diagnosis. Continue reading
A major global report was released today on obesity and the news is grim. The numbers of overweight and obese people around the world have increased dramatically since 1980, in both developing and developed countries and among all age groups, with the United States accounting for 13 percent of the world’s obesity.
The report was published today in The Lancet.
The findings bode ill for cancer prevention: aside from smoking, obesity is the single largest risk factor for cancer. AICR estimates that obesity is a cause of eight cancers, including postmenopausal breast, colorectal and ovarian. Obesity also plays a major role in other chronic disease, such as type 2 diabetes, which also links to increased cancer risk.
The study included data from over 180 countries. Study researchers systematically identified surveys, reports, and studies that provided Body Mass Index data. A BMI of 25 and over is categorized as overweight; 30 and over is obese.
The Lancet report estimates that worldwide, the proportion of adults with a BMI of 25 or greater increased between 1980 and 2013 from 29 percent to 37 percent in men, and from 30 percent to 38 percent in women. Continue reading
