The Health Profile in Denmark 2017 shows that more than half of the adult population has overweight. Large groups of people, not just in Denmark, but all over the world, become more and more obese. Obesity is not just obesity. Over half of those with obesity have high blood pressure, type 2 diabetes, all sorts of complications. All these complications cause more morbidity and a shorter lifespan and more mortality. In adulthood overweight is associated with more than 25 cancer diseases. That’s a lot of diseases, which in many ways, ruin people’s lives. That way we have to understand, that obesity is a huge threat to our health, against our opportunities to live a healthy and happy life. And that’s why we have to take obesity seriously, and we need to understand how brilliantly obesity can defend itself, and we have to act to do something about it, both for ourselves and for our next of kin.
