Once the festive period is over many older adults will be looking to shed some excess pounds. New research has shown that intermittent, low-carbohydrate diets are more successful than standard dieting and could also be a possible intervention for breast cancer prevention. Researchers at the University of Manchester have discovered that restricting carbohydrates two days per week is superior to a standard, daily calorie-restricted diet for both reducing weight and lowering blood levels of insulin, which is a cancer promoting hormone. However, they stress that further study is needed. "Weight loss and reduced insulin levels are required for breast cancer prevention, but [these levels] are difficult to achieve and maintain with conventional dietary approaches," Dr Michelle Harvie, author of the study, explained Researchers have previously confirmed the link between breast-cancer risk and physical characteristics of insulin resistance and higher-than-normal sex hormones in a woman's bloodstream. The study showed that women with abdominal body fat, oily skin and excess body hair - signs of higher than normal sex hormones in the blood stream - were at greater risk of developing breast cancer.
