| More and more people are coming under the umbrella of fatness in modern times. Not just adults, but even children are getting overweight. Today some of the newborn babies are also born fat. It has been proved that the people living in the developed Western countries are more likely to become overweight. There are a number of causes behind this.

Most of the developed Western countries are cold ones. Nature demands that people eat the food that can somehow make them stand the coldness. Therefore, wine fatty dairy products, bread, junk food and red meat become an important diet in these countries. However, the blame cannot be entirely put on the unhealthy eating habits of the people. Technology allows them to import almost all the foods products that they do not grow. Although some healthy food are grown in the countries nowadays, the quantity is very limited. It is not enough to meet the demand. So whentheyare not available and fatty foods are cheaper, then people prefer to go for the eating habit that they have always been following. |
