The World Obesity Atlas 2023, published by World Obesity Federation, predicts that the global economic impact of overweight and obesity will reach $4.32 trillion annually by 2035 if prevention and treatment measures do not improve. At almost 3% of global GDP, this is comparable with the impact of COVID-19 in 2020.
- The majority of the global population (51%, or over 4 billion people) will be living with either overweight or obesity by 2035 if current trends prevail. 1 in 4 people (nearly 2 billion) will have obesity.
- Childhood obesity could more than double by 2035 (from 2020 levels). Rates are predicted to double among boys to 208 million (100% increase) and more than double among girls to 175 million (125% increase) and are rising more rapidly among children than adults.
- Lower income countries are facing rapid increases in obesity prevalence. Of the 10 countries with the greatest expected increases in obesity globally (for both adults and children), 9 of those are from low or lower-middle income countries. All are from either Asia or Africa.
