It makes sense that we could become self conscious about our appearance when we spend all day in virtual meetings and classes. It's like holding a mirror in front of the face for an entire day, multiple days a week. With that frequency, there's way too much opportunity to self critique and become dissatisfied with the way we look. There are also way too many other people to compare ourselves to.
As a society we need to stop commenting on the way people look and on what they eat. The commenting only reinforces fat phobia and the belief that weight loss makes us more attractive or healthier. For someone with an eating disorder, commenting on their weight can either reinforce the weight loss or promote feelings of shame and guilt. Both of these can drive the person deeper into the disorder. So the next time you feel tempted to comment on someone's change in appearance, bite your tongue.
