Today we discuss the Science behind Intermittent Fasting, like every 'The Science Behind' episode we start with discussing what we already know or don't know. Then we study the literature and discuss what is known and what we have learned. We do this because in these times so many people form an opinion on very little information and we want to show that also scientists need to do their research first. This first episode is already a good example of how what you think you know can be very wrong and why it is so important to study a subject before forming an educated opinion.
