HW. CW. LW. GW1. GW2. GW3. UGW.

If you have (or have had) an eating disorder (or dieted and used online forums), chances are you know what those acronyms mean. And if you have browsed blogs written by eating disorder sufferers, chances are you have come across these acronyms too. After all, they are a prominent feature of many such blogs.

If you are lost, I’ll fill you in: the acronyms stand for Highest Weight, Current Weight, Lowest Weight, Goal Weight 1/2/3, and Ultimate Goal Weight (UGW).

Researchers call this difference weight suppression (WSmore specifically, the highest adult body weight) and one’s current weight). It … Continue reading →

Today, I’m going to discuss a study that suggests over-exercise in disordered eating patients is associated with suicide behaviour.

Suicide rates in eating disorder patients are high. One meta-analysis suggested that out of all eating disorder related deaths, 1 in 5 are suicides. (Keep in mind, these numbers are really hard to pin down as they depend a lot on the sample population, sample size, and how the authors did their statistics, among other things.)

Another analysis found that the standardized mortality ratio (ratio of observed deaths in the study sample/expected deaths in the population of the same age but without the disease/disorder you are studying) for suicide in eating disorders was 31 for patients … Continue reading →
