This book contains basic information, specific and easy to understand about the problematic that Obesity and excess weight poses to the world's population. At this time, Obesity is one of the greatest problems that plague the health of societies, bringing to billions of dollars the treatment costs and increasing day by day the number of deaths directly related to this phenomenon. This work is intended to raise awareness in young people and adults of the many risks that arise from a lack of nutritional balance and incorrect feeding. It is this way that this data collection provides an alert and invites us to reflect on the theme of food. Very important to be noted is that Obesity is hitting the world in general and sharply the youth and children from the majority of developed and developing countries. If we get through this effort to raise people awareness of the problems associated with obesity then we will have achieved the objective reason for us to prepare this research. We thank all the people who encouraged us to publish our work and constantly supported us to achieve our goals.
