Firstly, our lives have become busier and we do both a lot more and a lot less at the same time. For a start we don't physically move as much, with more of us working in sedentary jobs, spending much of the day sitting. We drive rather than use our legs and walk - we watch television and use mobile phones and devices for hours on end. We will often take shortcuts wherever we can.

Secondly, we are eating far more unhealthy foods and not enough good stuff. Portion sizes have gone up, but fruit and vegetable consumption has gone down. We grab fast food instead of a packed lunch and order take-away instead of cooking a meal at home. Sugary treats and salty snacks have gone from a 'sometimes food' to every day indulgence, with entire supermarket aisles dedicated to chips, lollies, cakes, biscuits and soft drink.

Basically we are opting for ease instead of health. It is all too easy to think it's normal, but it's not. In fact, it's creating a huge problem for us, our health and society at large.
