Although I can see how running could have helped in the first few posts, my experience is rather different.
First of all, I was an anorexic for about 3 years between the ages of 15 and 18. I was not a runner back then. Between the ages of 18 and 23 I still suffered with an “obsession” over food, and although I was not starving myself, I still had abnormal attitudes towards food and eating. At 24 I started running, in the hope that I would be able to become fitter and healthier, and in the hope that it would help me with my eating. However, 3 years on, I am still running, but I am still suffering with abnormal eating.
Running has made me focus on food as fuel, i.e. the physical responses of the body to certain foods, the benefits that some foods provide and the foods that are best avoided for physical exercise. However this has just furthered my obsession over food. This distinction between “good” and “bad” could be an unhealthy one. Without going into details about my eating habits, I can say that I try so hard to consume the “good” foods in order to improve my running (and loose weight), but inevitably binge on the “bad” foods because I feel I deprive myself of some of the pleasures (this is describing it VERY simplistically).
Also, running has furthered my negative self image. I have always felt rather big (even though I have a BMI of just under 21, which is bang in the middle of the “normal” range for women), and self critical about my body. But since joining a club and participating in more serious races, I have found myself comparing my body to other runners’, and feeling even worse. I feel that the “better/faster/more serious” runners look down on me, because carrying a few extra pounds makes me a less fast, less serious runner. Again, this reinforcement of a negative self image is a major contributor to the development (or exacerbation) of an eating disorder.
So, as it has been in my case, I think an eating disorder can push one to running (i.e. running is used as an aid to boost the poor self image, or further weight loss), but, vice versa, running can promote eating disorders, as preoccupation over food and body and striving for perfection and control may induce disordered eating.
The feeling of “control” is a major issue in both eating disorders and running. Similarly, the want to push yourself further and further. Of course, the relationship between eating disorders and running can be a complicated one (which is why it has helped some but made others worse), perhaps governed by external factors, which could also explain the fact that the link between EDs and running is present for some and not for others.
This is my experience of the association between the two, EDs and running – a vicious cycle, which I am so desperately trying to escape. One would think that running, such a natural, endorphin-inducing healthy pastime would be beneficial, but for me it has and is only making things worse.
