CMV: Fat Feminism is a warped denial of medical studies

I'm a feminist, pretty much agree with most of the movements, but I cannot for the life of me understand this one. I understand not shaming people because it empirically doesn't work and can lead to mental health issues. I understand reducing social stigma, subsequently not socially excluding fat people. I understand that much of the bodies depicted of women (and men) in our media are not attainable by most people, and that making this the standard is unfair and puts unnecessary pressure on many women, leading to eating disorders and shame.

All of that is well and good, BUT...

Obesity IS a health risk. The health studies done on obesity are not just done to "confirm our societal standards of beauty." Encouraging fatness is definitely not a wise decision, and the derision felt by fat people at the doctor's office or the insurance clinic is BECAUSE it's expensive to treat people who's body size is slowly increasing their chance of death, and ultimately futile if they don't change their lifestyle habits. 

So please, someone explain to me, why I should be a fat feminist, because as it stands, the "pros" are already encompassed in general third wave feminism, and the "cons" encourage misreading empirical data.

Can you give examples of feminists encouraging people to be fat? I've never seen that. Refusing to shame people for being fat is not the same as encouraging them to be fat. In a lot of cases, encouraging people to lose weight is just concern trolling, pretending to care when it's really just fat shaming by another name.
