Yes. Obesity is far more complex than that, I'm also looking at the global perspective.
Obesity to me is about lack of resources for better nutrition (though companies push junk pretty hard), lack of education, and lack of will power.
FWIW I'm substantially overweight despite being poor enough to need to miss meals in the past couple of years.
So give people BI and they'll just get blazed/drunk all the time, and make other mischief, is that your assessment?
