A new Lancet study reveals nearly three-quarters of U.S. adults are overweight or obese, a sharp rise from just over half in 1990.
Obesity among adults doubled to over 40%, while rates among girls and women aged 15–24 nearly tripled to 29%.
The study highlights significant health risks, including diabetes, heart disease, and shortened life expectancy, alongside projected medical costs of up to $9.1 trillion over the next decade.
Experts stress obesity’s complex causes—genetic, environmental, and social—and call for structural reforms like food subsidies, taxes on sugary drinks, and expanded treatment access.
If I suddenly started eating 15000 kcal of mostly sugar and fat each day, it would have a detrimental impact on my health. Regardless of my education or income.
So to me it seems like the effect is in reverse. If we changed society to make it easier for people to make healthier choices, then the general health would improve. But the actual improvement would come from calorie intake, food quality and activity levels.
But I absolutely agree that having limited access to healthy food, and living in a area where walking could be unsafe makes it incredibly hard to be healthy.
