"There are no financial costs associated with fasting one day per month. The article generally presents data well: While at the top it uses the phrase ""40 percent less likely to be diagnosed with heart disease,"" later in the text it explains that 67 percent of the non-fasters were diagnosed, compard to 59 percent of fasters. Providing both measures is useful. The article also lays out the study’s methodology in considerable detail. The article cites the two important safety issues regarding fasting: That it can be dangerous for diabetics, and that it can depress metabolism and possibly make weight gain more likely. It should also have said that anyone who wants to fast should consult their doctor first. While the article reports that the study was presented at an American Heart Association meeting, it did not explain that this means the data has not been peer-reviewed or published – and as such carries less credibility until (or if) it is published in such a journal. The article also failed to point out an observational study of self-reported behavior is a less powerful type of evidence than a prospective clinical trial. The risk in this study of ""Healthy user bias"" – the fact that people who choose to fast may have healthy characteristics that others do not – should have been emphasized. The article also permits the researchers to overinterpret some data. It quotes the researchers as saying the results apply to non-Mormons too. But only 8 percent of the survey group of 515 – or 41 people – were not Mormons. Conclusions of disease prevalence based on such a small sample size are premature. The article does not exaggerate the consequences or prevalence of heart disease. This article was based on a presentation at a medical meeting. It included interviews from two sources: The study’s author, and an independent expert on the subject of diet and heart disease. The article states that quitting smoking also reduces heart disease risk. But it fails to indicate that a more common approach to reducing heart risk is controlling what and how much you eat rather than when. It would have been useful to know how much benefit this group of fasters saw compared to a similar group that used more common dietary measures to reduce heart risk. The article also fails to mention other common and effective ways to reduce heart risk, such as controlling high blood pressure and lipids, taking aspirin, etc. The activity studied, refraining from food and drink one day per month, is available to anyone. The article correctly implies that little research has been done on the cardiac benefits of once-a-month daily fasting. There is no evidence the article is based on a press release."
