Using weight to define health is inaccurate, unscientific prejudice. It directly fuels discrimination in the workplace, from insurers, in medical care, and in social interactions. The war on so-called "obesity" [sic] is a war on fat people. Doctors already exhibit dangerous levels of weight bias. Fat people deserve care, not condemnation. Correlation≠causation. Behavior≠BMI. Weight≠health. Hate is not good for public health.
