Intermittent fasting can be a double edged sword!!

On one hand, it could help us to lose our excess body weight but on another hand it can also result in heart diseases in us. Shocking?

The intermittent fasting has gained huge popularity in recent times. Here, persons eat their meals in a restricted time span of a few hours  (8 hours per day)and not eat any food for the remaining time of the day. Recently, research study has brought out that intermittent fasting could be dangerous as it can lead to heart diseases etc in us. The research has been published in Diabetes and Metabolic Syndrome. In the research study, as many as 19000 individuals were taken into consideration. Point is that the research was based on the National Health and Nutrition Examination Survey or NHANES.

It was revealed by the research study that participants who restricted eating to an 8 hour time frame every day had 135% more chances of getting affected by heart related illness like heart attacks, strokes etc when compared to participants who eat food in the 12 hours to 14 hours range time..
