Obesity is becoming an increasingly serious problem and is officially considered the number 1 cause of death. According to World Health Organisation estimates, in one decade the numbers have tripled. Now more than 1 billion people worldwide are obese – 650 million adults, 340 million adolescents and 39 million children. This number is still rising and by 2025, another approximately 167 million people – adults and children – will become less healthy because they are overweight or obese.
