Obesity has emerged as one of the gravest health risks for our society. It can affect anyone - young or old – and cause serious and life threatening consequences. For this reason it cannot be looked upon as an appearance issue only. With the growing fast food industry and people deciding to spend their free time in front of a TV set or computer rather than outside doing physical activities it can be estimated that the number of population that is overweight will increase in the future, affecting more and more people and their everyday lives.
