Causes of obesity and overweight


The main cause of obesity and overweight is when the energy between the calories consumed and the calories expended is imbalanced. On a global level, there has been:

an increase in the intake of energy-dense foods thatgives high fat and sugars; and
an increase in the rate of physical inactivity because of the increase in sedentary nature of the different types of work, different modes of transportation and increase in urbanization.

The higher the BMI, the higher the risk of having these noncommunicable diseases.

Children with obesity have higher chance of having breathing difficulties, fractures, cardiovascular disease, insulin resistance, disability, psychological effects, andmay even die prematurely.
