What the Science Says About Intermittent Fasting

It's long been known that calorie restriction can increase the lifespan of certain animals. More recent research suggests that intermittent fasting can provide the same health benefits as constant calorie restriction, which may be helpful for those who cannot successfully reduce their everyday calorie intake. Both intermittent fasting and continuous calorie restriction have been shown to produce weight loss and improve metabolic disease risk markers. However, intermittent fasting tends to be slightly more effective for reducing insulin resistance.
