4:20 PM | Histamine and Anorexia Nervosa
Most of us have at some point in our lives taken antihistamines–drugs that block the action of histamine (e.g., Claritin, Allegra)–to relieve allergy symptoms. And while histamine is best known for its role in the immune response, it also has many other important roles in the central nervous system. In the brain, histamine release is important for arousal (this is why antihistamines tend to make us drowsy). It has also been implicated in regulating appetite, taste […]

6:45 PM | Making Connections: Peer Support and Eating Disorder Recovery
I feel like a broken record when I say that we continue to lack an evidence-base for most “alternative” forms of support for eating disorders. As I’ve noted in prior posts, just because something is not evidence based does not mean it does not work for anyone; often, an evidence base is established when researchers can secure enough funding to run a randomized-controlled trial (RCT) that would act as evidence. Even when an RCT has been run, it is hard to say that one form of […]

6:03 AM | Quantum Algorithms Via Linear Algebra
Announcing publication of our textbook with MIT Press By permission of Nataly Meerson, artist : source Richard Feynman had a knack for new ways of seeing. His Feynman diagrams not only enabled visualizing subatomic processes, they also rigorously encapsulated an alternative formalism that cross-validated the equations and procedures of quantum field theory. His 1948 path-integral […]

1:27 PM | Treating Severe Anorexia Nervosa in the Community
Can treatment for severe anorexia nervosa be delivered safely in a community setting? According to a recent paper by Calum Munro and colleagues (2014, open access), the answer is yes. In 2001, a systematic review by Meads, Gold, and Burls found that inpatient treatment is not more or less effective than outpatient treatment for individuals with AN. Of course there will always be patients who will require inpatient care, but given the high cost, lack of clear efficacy, and known risks, it is […]

9:57 PM | Fat Talk Free Zone: What is the Impact of Fat Talk on Body Dissatisfaction?
There has been a veritable explosion of “anti-fat talk” movements in the body image and eating disorder prevention realms over the past few years. Indeed, campaigns like the Tri-Delta Sorority Fat Talk Free week have become relatively well known. Events like the “Southern Smash,” where participants literally smash scales are other iterations of this social phenomenon encouraging a more positive conversation around bodies. I am, of course, a fan of the idea that we […]
