Many Australians need to lose a few kilos. New diets, programs and books telling us how to lose weight appear every day, but it's important to follow an eating and exercise plan that will help you stay healthy in the long term.

Nearly two thirds of Australians are overweight or obese. Carrying extra weight increases your risk of chronic diseases like heart disease and stroke, type 2 diabetes and some cancers. If you are above a healthy weight, losing just a few kilos can lower your risk of health problems.

To lose weight, you need to eat and drink fewer kilojoules than you use. (A kilojoule (kJ) is a measure of the amount of energy a person gets from food. The average adult will burn about 8,700kJ per day, although the amount varies depending on age, gender and level of activity.)

A weight-loss diet restricts what you eat so you lose weight.

A 'fad' diet is an eating plan that often promises rapid weight loss but is not based on science. Often, fad weight-loss diets want you to cut out entire food groups. This could mean you dont get all the nutrients the body requires.

They should not be confused with vegetarian or vegan diets. These are not weight-loss diets and, with good planning, vegetarians and vegans can get all the nutrients they need.

It's important to choose an eating and exercise plan that is healthy and that suits your lifestyle. Following a healthy eating plan is better for your health and will mean you are more likely to keep the weight off long term.

The weight-loss industry is worth more than $635 million in Australia. However, it is important to realise that not all diets work and some can also be potentially harmful. Going on a very restrictive fad diet can lead to:

Most of the weight you lose on a fad diet is water and lean muscle, not fat. That's because when you eat too little, your body breaks down muscle to get enough kilojoules. It is easier for your body to get kilojoules from muscle than from fat.

To maintain a lower weight permanently, it is better to change your eating behaviour in a way you can keep up long term.

Fad diets are very popular in Australia. Common fad diets include those that recommend cutting out sugar, drinking meal replacement shakes, following a low carbohydrate/high fat diet, detox diets, the raw food diet and the Dukan diet.

Avoid a diet that:

The key to healthy weight loss is to focus on a healthy lifestyle with plenty of regular exercise and a balanced diet with foods mainly from these 5 healthy food groups:

You should also drink plenty of water, and limit your intake of foods that contain saturated fat, added sugars, added salt and alcohol.
