How to lose weight

About managing your weight

Being overweight or obese means you have too much body fat. Being overweight or obese is not just about how you look – it can affect your day-to-day life, making you:

Over time, the more body fat you have and the more you weigh, the more likely you are to develop health problems such as heart disease, high blood pressure, diabetes, gallstones, breathing problems, and some types of cancer.

New Zealand, along with the rest of the developed world, is getting fatter. Results from the recent New Zealand Health Survey showed that one in three adults are overweight and a further one in three adults are obese. However, obesity is less common among older adults, particularly those over the age of 75.

Why am I overweight or obese?

Your weight is the result of many factors. These factors include environment, family history and genetics, metabolism (the way your body changes food and oxygen into energy), eating behaviour or habits, and more. You can't change some factors, such as family history. However, you can change other factors, such as your lifestyle habits.
