This may be controversial, but honestly - I don't think so. Outwardly they spout all this HAES bullshit, but it's just not possible for people to believe that. How in the fuck can you say "I'm healthy" and then stab yourself with an insulin needle. To me, at least, it's much more likely that they use it as a coping mechanism: "if I tell myself that nothing is ever my fault and I don't have to accept that I'm 100% responsible for reaching this state. I can blame someone else (corporations) or something else (gunetiks)." Deep down inside they know it's a load of crap, and when they no longer need the coping mechanism (because they lost weight) they don't spew their HAES bullshit anymore.
