What if everything we think we know about the science of obesity is wrong?

According to a recently published review in the American Journal of Clinical Nutrition, what we think we know about what causes obesity — and why so little progress has been made in the field — is wrong and has been for years. And new data from the Robert Wood Johnson Foundation shows that 1 in 6 young people ages 10-17 nationwide and more than 1 in 5 Texas youths are obese, with sharp disparities along racial and socioeconomic lines.
