Obesity:
Obesity is a treatable medical problem. It caused chronic health problems,
these problems can be controlled if we work hard to control our weight.
Our bodies need some fat to give us energy
to keep our bodies running, keep us warm, and protect our internal tissues.
Enlarged fat cells produce the clinical problems that are associated with obesity, either because of the weight or mass of the extra fat or because of the increased secretion of free fatty acids and numerous peptides from enlarged fat cells.
Obesity means that someone has more fat on his body than is
considered a healthy average for his height and bone structure.
The same amount of energy IN and OUT over time = weight stays the same.
More IN than OUT over time = weight gain
More OUT than IN over time = weight loss

BMI (Body Mass Index):
The BMI is the tool that used to estimate overweight and obesity.
It's defined as a person's weight in kilograms divided by the square of his
height in meters (kg/m2).
Using a measure such as BMI allows for a person’s weight to
be standardised for their height, thus enabling individuals of different
heights to be compared.
