The Science of Eating Disorders: Why People Get Anorexia Nervosa

You know the hardest part about having an eating disorder?

It’s not feeling cold all of the time.

It’s not being weak and fragile.Eating Disorders

It’s not the hunger.

It’s having no idea why, or how, you got anorexia.

I’ve been anorexic since I was 12 years old, and the worst part of the disease is feeling guilty. You feel like you’re “defective,” and that it’s somehow your fault.

Luckily, new research has come out that helps shed light on exactly why some people become anorexic, like me, and others don’t.

In this podcast, science journalist and former anorexia sufferer Carrie Arnold is going to teach you what really causes eating disorders. Here’s what we discuss:

  • The three main causes of anorexia.
  • The most underrated warning signs that someone might have an eating disorder.
  • How your brain function changes when you get anorexia.
  • How to help, or at least talk to, someone with an eating disorder.

    So well done! I struggled with anorexia for several years and this really appealed to both the recovering person but also the science geek in me. It’s such a relief to know that so many of the things I was feeling were real. It’s also nice to know I’m not the only one that has had these experiences. Thank you!

    Good day! I know this is kind of off topic but
    I was wondering if you knew where I could find
    a captcha plugin for my comment form? I’m using the same blog platform as yours and I’m having difficulty finding one?
    Thanks a lot!
