A drug that slowed ageing and protected the body from diseases such as cancer would no doubt cause considerable excitement around the world. While there is no such miracle drug, there is a way to trigger these effects in the body without taking any medicine at all — simply by fasting. You probably think this sounds too good to be true. So what’s the evidence?
There are few carefully conducted large-scale clinical trials. This is not surprising given the difficulties of requiring participants to give up eating over several days. The best empirical evidence, therefore, comes from studies on laboratory organisms such as mice, flies or even yeast. These clearly demonstrate that periodic fasting protects living creatures from most diseases and improves overall health.
