We’ve been talking a lot about preventing liver cancer here with the release of our new report. Among other factors, the report concluded that obesity increases risk of liver cancer — a cancer that can stem from non-alcoholic fatty liver disease (NAFLD).
Now comes a study that suggests overweight adults who do even 15 minutes of daily exercise —regardless of intensity or weight loss— can reduce the risk of both liver fat and belly fat, compared to those who are inactive. Belly fat, also called visceral fat, is a sign of poor metabolic health and another risk factor for many cancers.
Non-alcoholic fatty liver disease has become the most common cause of liver disease in the US; it can lead to cirrhosis, which could develop into cancer. People with non-alcoholic fatty liver disease have extra fat in their liver that doesn’t come from alcohol. Weight loss and exercise are the basic recommendations for obese people who have NAFLD. But what intensity exercise and how much was the focus of this study. Continue reading
Perhaps you’ve struggled to find a diet that works for you, despite the almost overwhelming number of choices. And research seems to yield varying results. This is important because being a healthy weight can lower your risk for chronic diseases like type 2 diabetes and many cancers.
A new study of popular diets in the Annals of Internal Medicine, completed a systematic review of controlled trials of popular diets and weight loss programs to look at their effectiveness at 12 months. These included Weight Watchers, Jenny Craig, Medifast, Atkins, SlimFast, eDiets and the LoseIt! app among others.
The authors concluded that Weight Watchers and Jenny Craig programs have the most robust evidence for people losing weight at one year when compared to doing nothing or simply getting general education about weight loss. They cited Nutrisystem as showing promise after a few months, but it lacks long-term results. These programs are all considered to be high intensity – meaning they include at least 12 individual or group counseling sessions. Continue reading
It’s what every examination of the science of diet and health requires. For too long, authorities have demonized specific foods in an attempt to explain poor health outcomes, or anointed the latest “superfood” a panacea against disease.
That’s more or less the gist of a new article in the New York Times, “Red Meat is Not The Enemy.” The author suggests that experts historically “cherry-pick” data from individual studies to single out one nutrient or food in an attempt to determine its role in human health.
The Totality of Evidence
We agree that this can be a problem, and a misleading one. And that’s precisely why, at the American Institute for Cancer Research, when we perform our ongoing analyses of the global evidence on the connections between cancer risk and lifestyle (read: diet, weight, physical activity), we do so using systematic literature reviews and meta-analyses. (We call it the Continuous Update Project, or CUP.) Continue reading
