Have you ever wondered if some people simply have a fast metabolism? You know the kind of people that seem to be able to eat anything and still maintain a healthy weight? Does your metabolism slow as you age? What about the effect of the menopause? And are intermittent fasting and certain supplements evidence based ways to speed up your metabolism?

These are the questions I put to Dr Adam Collins, researcher at University of Surrey where I completed my Nutritional Medicine Masters. Dr Collins is a well-known expert in metabolism and nutrition science. He's done a lot of research on energy expenditure, intermittent fasting, and how different diets affect metabolism.
