Global Cost of Obesity Is $2 Trillion Annually TIME Health Obesity Obesity Now Costs the World $2 Trillion a Year Half the world's population could be obese by 2030, warns a McKinsey Global Institute report The global cost of obesity has risen to $2 trillion annually, according to a new report, more than the combined costs of armed violence, war and terrorism. The McKinsey Global Institute report says currently almost 30% of the world's population is obese, and that if present trends continue, that almost half the population will be clinically overweight or obese by 2030. The report cautioned that no single solution would reverse the problem, instead calling for a "systemic, sustained portfolio of initiatives" to tackle the crisis, such as better nutritional label, healthier food at schools, advertising restrictions on fatty foods and beverages, and public health campaigns.
