In the battle of beverages, diet drinks made the headlines this week, beating out water as a weight loss aid according to a new study. Understanding how our food and beverages may affect weight gain or loss is important to cancer prevention, because being overweight or obese is a major risk factor for eight cancers, including colorectal and post-menopausal breast.
The study adds to the limited, but growing body of human research on diet beverages. The role of diet beverages in weight control is controversial, but the role of sugary beverages is not. AICR recommends avoiding sugary sodas and drinks because they are strongly linked to weight gain, overweight and obesity.
The study, published online in Obesity, found that of the approximately 300 overweight participants, those consuming the diet beverages lost more weight over 12 weeks than the group consuming water. The difference was small, but significant, with the diet drink group losing an average of 13 lbs and the water group, 9 lbs.
For the trial, one-half of the participants were instructed to drink at least 24 ounces of water daily and not to consume any diet beverages. The other half were told to drink at least 24 ounces of diet drinks, but they could also drink water. 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
The health risks of obesity have been in the news lately, including in our latest report showing a link between obesity and ovarian cancer risk. The stories have sparked a lot of conversation about BMI (Body Mass Index), a number used to easily determine a person’s body fatness.
Maybe you know your own BMI. But what is BMI and what does it mean to you?
The formula for BMI is:
weight (kilograms) divided by height (meters)2
weight (pounds) divided by height (inches)2 x 703
A BMI of 18.5 – 24.9 is considered healthy; 25-29.9 overweight and 30 and above obese.
BMI is very useful for studies looking at a large number of people and trying to determine if, on average, BMI links to disease risk or health status in some way. But for individuals, BMI is a starting point to determine whether your weight is in the healthy range for you. Continue reading
