Metabolism is a term that describes all the chemical reactions in your body that keep your body alive and functioning. It’s most often used to describe your basal metabolic rate, or the number of calories you burn at rest.

Think of your metabolism, like your car. If you fill your car with poor quality fuel or you let it run out of petrol, it will have no power and won't operate efficiently. The same can be said for your body. If you neglect it, it will be sluggish and you’ll burn less calories at rest. And this is not a favourable position to be in, as it makes it hard to manage your weight.

Many factors can affect your metabolism including your sex, age, lifestyle and weight. And it definitely slows down as we get older. BUT, the good news is, there are things you can do to speed it up. Join Dr Nick as he takes you on a deep dive into the science to find out.
