Healthy weight
The keys to achieving and maintaining a healthy body weight are to enjoy healthy eating and be physically active. To achieve a healthy body weight, balance the kilojoules (energy) coming into your body through food and drinks with the energy being used up by your body through regular physical activity.
Being overweight is a risk factor for heart disease and also contributes to high blood pressure. If your weight is a health risk or it's affecting your enjoyment of life, then you need to do something about it.
If you really want to lose weight, keep the weight off and be healthier, you need to change your eating patterns and increase your physical activity levels. Just doing one or the other is usually not enough.
Despite what various books and diets may say, losing weight in a healthy way is not quick and it's not simple. Fad or crash diets are often unhealthy and are not helpful with losing weight and keeping it off in the longer term. Remember that the health benefits and what you can gain from your life make the effort worth it!
