The posters to this blog regularly state medical claims that can be disproved with a quick google search. They spew hatred against thin people, who are apparently actively oppressing fat people simply by not being fat. They give out advice to readers that actively damages a person's health, and if they are challenged they revert into some sort of tantrum-like typing style in response (which afterwards they use these tantrums as a way of explaining how they won the "argument").

They are promoting a unhealthy lifestyle, giving out horribly inaccurate medical advice and fact, perpetuating and feeding a hysteria of fat discrimination. They are thin shaming, using outdated medical studies and journals to back their points up, and more often than not, actually reading the whole entire studie disproves their point. They are miseducating people and spreading a wealth of lies, perpetuating an unhealthy ideal and life style. They are claiming long term weight loss is literally impossible. And they are refusing to post anything that opposes what they said and doctrine.
