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.)

Postmenopausal women who are overweight — and especially obese — have a greater risk of developing breast cancers, finds a new study that highlights the importance of preventing weight gain, as it also raises questions about whether losing weight necessarily reduces that risk.
The study adds to a consistent body of research showing that overweight and obesity increases women’s risk of postmenopausal breast cancers. It was published yesterday in JAMA Oncology.
AICR estimates that a third of US breast cancers could be prevented if women were at a healthy weight throughout life, were active and did not drink alcohol.
In this study, as other research has seen, the heavier the women, the greater the risk. Women categorized as the most obese were at almost double the risk of the most common type of breast cancer, ER-positive, along with PR-positive tumors. These cancers are fueled by the hormones estrogen and progesterone, respectively.
The study used data from approximately 67,000 women who were all part of the Women’s Health Initiative trials. That study focused on preventing certain cancers, heart disease and osteoporosis. When the women entered the study in the mid 1990s they were 50 to 79 years old, and they were weighed. They also answered questions about their lifestyle habits, medical history and other health risk factors. After that, they were weighed annually and had regular mammograms. Continue reading
