On the surface, complimenting someone’s weight loss seems like a benign and positive affirmation, but there are a number of reasons why doing so is problematic.

First and foremost, unless we have been told by the individual that their weight loss was intentional, we really have no clue as to why someone is losing weight. It could be due to illness, grief, or depression. It could also be as a result of an eating disorder (ED). Many of my patients say that comments about their weight loss when they were in the throes of their eating disorder fueled the disorder and made them feel like they had to keep up their disordered behaviors in order to keep their body “in check.” This goes double for patients with anorexia who are in larger bodies. These individuals often go undiagnosed with an ED because their weight loss is seen as a positive thing, never mind that they are engaging in extreme restriction and over-exercise to achieve this loss.

While I was never formally diagnosed with an ED, I myself remember when I was a teenager and engaged in very disordered eating and exercise habits and ended up losing a significant amount of weight in a short period of time. Despite the fact that I had lost my period, had very little energy, avoided going out to eat for fear of having to eat “junk” food, and overall felt awful and obsessive, I got compliment after compliment from family, friends, and even from my doctor. I even remember my doctor saying to me, “I don’t care what you are doing to lose the weight, just keep doing it!” I cringe just thinking about it!

Another reason to stop complimenting weight loss? It inherently implies that there was something wrong with the person’s body before they lost the weight. Think about it – do we ever comment on someone gaining weight in a positive light? Nope. These weight loss compliments also imply that being smaller or skinnier is better than being larger. The truth of the matter is that bodies come in all shapes and sizes, and they all deserve respect. Placing smaller bodies on a pedestal reinforces the idea that people in larger bodies are less than. This is weight stigma, and it has been shown to negatively affect us not only psychologically, but physically as well. Furthermore, since we know that 95-98% of intentional weight loss attempts result in weight regain, the silence when someone regains the weight they lost can be deafening.

Finally, and possibly the most important reason, is to stop modeling this behavior for our children. Little ones are like sponges, and from a young age, they are acutely aware of our society’s dislike of fat people. One study found that children aged 6 to 11 hold considerable negative attitudes towards their heavier peers, being more likely to describe these “overweight” peers as “mean, stupid or dirty” than average-weight peers. Other studies found that “nearly a third of children age 5 to 6 choose an ideal body size that is thinner than their current perceived size” and that “by age 6, children are aware of dieting and may have tried it”. When we compliment another’s weight loss, we are telling our kids that to be smaller is better and that being fat is a bad thing.

What can we do instead? Don’t comment on another person’s body. Full stop. If you feel compelled to give a compliment, try complimenting the person’s kindness, humor, intelligence, or other attributes not related to body shape or size.
