I would never claim that income/poverty is the root cause of obesity, as obesity poorly correlated with income in the US.
Obesity is prevalent in both the middle class and poor, with the middle class slightly leading the poor[1]
>39% of people ≤130% of the federal poverty line (FPL) are obese.
>40.8% of people 130 to 350% of the FPL are obese.
While individuals should be brought out of poverty for other reasons, it is not a cure-all for obesity. If anything can be implied by the correlation, it will make the problem worse, and the healthcare system should prepare for this.
