Overweight and obesity are both both labels for ranges of weight that are greater than what is generally considered healthy for a given height. They are defined by the World Health Organization(W.H.O) as an abnormal or excessive fat accumulation which can impair health.

For adults, overweight and obesity ranges are determined by using weight and height to calculate a number called ”body mass index”(BMI)

According to W.H.O, body mass index(BMI) is a simple index of weight for height that is commonly used to classify overweight and obesity in adults. It is used because, for most people, it correlates with their amount of body fat. The B.M.I can also be defined as a person’s weight in kilograms divided by the square of his height in meters(kg/m)

An adult who has a BMI between 25 and 29.9 is considered overweight. An adult who has a BMI of 30 or higher is considered obese.

Overweight and obesity are a results of energy imbalance. For each individual, this may be due to a combination of several factors. Individual behaviors, environmental factors and genetics all contribute to the complexity of the obesity epidemic. However, the choices a person makes in eating and physical activity also contribute to overweight and obesity.

How To Prevent Overweight And Obesity

Our bodies need calories for daily functions such as respiration, digestion, locomotion and daily activities. Weight gain occurs when calories consumed exceed this need. Physical activity plays a role in energy balance, because it uses up calories consumed. It is recommended that a person accumulate at least 30 minutes in adults and 60 minutes in children of moderate physical activity most of the week.

Even greater amounts of physical activity may be necessary for the prevention of weight gain, for weight loss or for sustaining weight loss.
