Obesity is the condition of being more overweight than is considered average or healthy.
The noun obesity was first used around 1610 and has origins in the Latin word obesitas, meaning "fatness" or "corpulence." During the Middle Ages, obesity was a sign of wealth and prosperity indicating that you had enough money to buy and eat all the food you wanted while others starved. Nowadays, research has shown that having too much fat can cause a number of related health problems. A healthy diet and fitness regime is a great way for someone to shed excess pounds and avoid obesity.
