Overweight and Obesity  




According to the World Health Organization (WHO), over the past 35 years, the number of cases of obesity has doubled: 1.9 billion adults - over 18 years of age - are overweight of which 600 million are obese.

About 13% of the world's adult population were obese in 2014, of which 11% were males and 15% were females.

39% of people over 18 in 2014 were overweight  : a figure not to be overlooked  !


1. Define overweight and obesity


Overweight and obesity are defined as an excessive accumulation of body fat which is harmful to health.

To estimate overweight in adults, we use a simple measure called the Body Mass Index (BMI). It corresponds to the weight divided by the square of the cut, expressed in kg / m2.


BMI = Weight (kg) / Height squared


For example, a person who weighs 60 kilos and is 1.64 meters tall, his BMI = 60 / 1.64 2 = 22.30

So his BMI will be located in  : HEALTHY WEIGHT





























However, it gives an approximate indication because it does not necessarily correspond to the same degree of adiposity from one individual to another.


2.   The causes of obesity and overweight  


The main cause of obesity and overweight is an energy imbalance between calories consumed and expended.

-        The calories consumed increased due to the high consumption of caloric foods high in fat

-        And the calories expended  decreased due to a lack of physical activity (sedentary, changes in modes of transport, etc.)


3.   The consequences of overweight and obesity  


A high BMI is a risk factor for chronic diseases such as  :
