According to a World Health Organization study published by The Lancet medical journal, obesity has increased alarmingly in low and middle income countries, particularly in Africa. World Obesity Day, held on 4 March, aims to raise awareness around what the WHO describes as an "epidemic".
While some of the populations in Africa still face undernutrition, others no longer have this problem, but their diet is of poor quality and obesity is on the rise, according to a WHO study released last week by The Lancet medical journal.
