ABSTRACT

Obesity is a medical condition in which excess body fat has accumulated to the extent that it may have a negative effect on health. People are generally considered obese when their body mass index (BMI), a measurement obtained by dividing a person's weight by the square of the person's height, is over 30kg/m2, with the range 25–30kg/m2 defined as overweight. Overweight is having extra body weight from muscle, bone, fat and/or water. Obesity is having a high amount of extra body fat. Body mass index (BMI) is a useful measure of overweight and obesity. Talk to your health care provider if you are concerned about your BMI. Many factors can contribute to a person’s weight. These factors include environment, family history and genetics, metabolism (the way your body changes food and oxygen into energy), and behavior or habits. Energy balance is important for maintaining a healthy weight. The amount of energy or calories you get from food and drinks (energy IN) is balanced with the energy your body uses for things like breathing, digesting, and being physically active (energy OUT): The same amount of energy IN and energy OUT over time=weight stays the same (energy balance). More energy IN than OUT over time=weight gain; More energy OUT than IN over time=weight loss. To maintain a healthy weight, your energy IN and OUT don’t have to balance exactly every day. It’s the balance over time that helps you maintain a healthy weight. You can reach and maintain a healthy weight if you: Follow a healthy diet, and if you are overweight or obese, reduce your daily intake by 500calories for weight loss. Limit the time you spend being physically inactive.
