Overweight is considered a condition in which excess body fat presents a health hazard. Abnormal accumulation of fat is diagnosed as obesity. To separate these two concepts, body mass index (BMI) is used.
BMI is not the only, but the most common method to evaluate body weight. Excess body weight is diagnosed in BMI of 25 to 30. The term obesity is considered when BMI exceeds 30. If abdominal obesity is suspected, other methods can be used.
Modern lifestyle is the main cause of overweight. Reduced physical activity is observed not only in adults but also in children. Usually, low level of physical activity is combined with excessive consumption of high-calorie foods in obese people.
People love to eat a lot and tasty and this is related with the mechanisms laid down by nature. Our body is tend to accumulate energy (fat), which can be expended if necessary. In an ancient person, fat was accumulated during the abundance period and consumed in more difficult times (such as drought or winter). Modern man rarely faces the lack of food products, so fat is accumulated, but not expended.
In order to enjoy food, it is not necessarily overeat. Frequent overeating causes heaviness in the stomach, heartburn, lethargy, apathy, and eventually overweight. In addition, overeating can form harmful habits and psychological problems difficult to get rid of.
