I remember when i heard this shit on a science podcats that tries to cut trough the snake oil bullshit a while ago. They called out truthers, homeopats, psychics, aids denialists and other crazies, but fat people? Nope, not their fault, HAES is the key. Was so pissed but his comment by the fat fuck guest on the podcast sent me over the edge.  Health At Every Size (HAES) has been tested under rigorous experimental conditions (randomized control trials) many times, and while it doesn't show dramatic weight loss, participants are less stressed, exercise more, had better metabolic profiles and psychological measures (see source below, including link to free full-text article). If the goal is well-being, the current system of fat shaming and dieting (weight normative) is the wrong approach to achieve that.
