'Obesogenic environment: We live very sedentary lifestyles, paired with fast food culture'

Rates of obesity and overweight are spiralling due to a "monumental societal failure" to tackle the problem, with more than half of adults and almost a third of children and young people set to be affected by 2050, according to a new study published in The Lancet. That represents more than 3.8 billion adults and 746 million children and adolescents. As we commemorate World Obesity Day, FRANCE 24's Genie Godula welcomes Dr. Karen Coulman, Senior Research Fellow and Obesity Specialist Dietitian at the University of Bristol.
