Diet gimmicks, gadgets and fads come and go like dress fashions. They all claim to be very effective because otherwise they would fail to attract those who want to lose weight. Unfortunately, many weight loss approaches are not nutritionally balanced and dangerous to the health and wellbeing of those who follow them for long periods of time.
You may have seen or heard about supplements that blast fat away, exercise devices that give you an instant ‘six pack’, or diets that guarantee a drop in two dress sizes in two weeks. There is no "miracle" pill, potion, gadget or diet that successfully helps you lose lots of weight in a short amount of time and keep it off. The only safe and certain way to lose excess body fat and maintain a healthy weight is to consume less energy (kilojoules) than your body needs and increase your level of physical activity.
