But outside of its believed spiritual benefits, fasting can also offer some pretty powerful physical and mental health benefits as well. Here are five health benefits of fasting:
This benefit may be both physical and mental, depending on how you choose to look at it. The self control it takes to refrain from eating and drinking for a period of time can be applied to other aspects of your life. In the 1960s, Dr. Matthew Maltz published a renowned book in which he proclaimed it takes 21 days to form a habit. Most religious fasts last way longer than that.
More recent research says the amount of time it takes to develop a habit may vary, depending on the person. But overall, based on both theories, daily consistency is key to developing discipline—and that’s exactly what fasting provides.
Diets that incorporate intermittent fasting have been linked to improved cardiovascular health. That’s because fasting lowers the probability some key risk factors for heart disease. Those factors include type 2 diabetes, high blood pressure, and obesity.
In a 2014 study, participants who alternated “feed days” and “fast days” experienced decreased insulin resistance. Researchers said that intermittent fasting could be a comparable alternative to calorie reduction as part of type 2 diabetes treatment.
Calorie restriction and exercise are, of course, science-backed ways to lose weight. However, in that same 2014 study, participants who alternated fast and feed days saw a reduction in weight as well. This isn’t some revolutionary concept though. Taking two to three days a week off from eating, too, reduces calorie intake. That, combined with consistent exercise, inevitably leads to weight loss.
Intermittent fasting may be the true fountain of youth. Studies dating back as far as 1982 have found a direct correlation between fasting and longevity. In fact, a study earlier this year found that “fast mimicking diets” actually reverses cell aging. Researchers admitted the results wholly depend on whether people consistently adhere to the fasting diet (which many participants were unable to).
