In the 20th century Obesity became common, so much so that in 1997 the WHO formally recognized obesity as a global epidemic. Obesity is definited as over body fat. Obesity is related with many diseases, particularly heart disease, type 2 diabetes, breathing difficulties during sleep, certain types of cancer, and osteoarthritis. Obesity is also defined as having a body mass index (BMI) of greater than 30.

Foods provide us with the nutrients we need for healthy bodies and the calories we need for energy. If we eat too much, however, the extra food turns to fat and is stored in our bodies — especially in your waist area. If we overeat regularly, we gain weight, and if we continue to gain weight, we may become obese.

WHO estimates that at least 400 million adults (9.8%) are obese, with higher rates among women than men. The rate of obesity also increases with age at least up to 50 or 60 years old. Obesity is an epidemic in the United States and in other developed countries. More than half of Americans are overweight-including at least 1 in 5 children. Nearly one third are obese. The only remaining region of the world where obesity is not common is sub-Saharan Africa. Obesity is on the rise in our society because food is abundant and physical activity is optional.

Obesity is of public health concern because of its association with serious medical complications and our modern world can trigger obesity and you must take action to stop this.
