Intermittent Fasting: More mentally harmful and less physically beneficial than claimed?
Intermittent Fasting and Disordered Eating Intermittent fasting is an eating pattern that limits food intake to specific time periods each day. There are various IF schedules, each differing in the length of fasting periods, ranging from several hours to an entire day. While intermittent fasting has gained popularity as a weight-loss strategy and is often…
Read MoreNew study highlights specific recovery needs of youth with ARFID
ARFID Characteristics During Hospital Treatment ARFID stands for Avoidant/Restrictive Food Intake Disorder. ARFID is an eating disorder where someone avoids food, but not due to concerns about weight or body shape. Unlike anorexia nervosa, where people’s disordered eating focuses on appearance and weight loss, ARFID food issues are often caused by things like lack of…
Read MoreEDGI2: The Next Wave of Eating Disorders Research
EDGI1 vs. EDGI2: What’s New in the Next Wave of Our Eating Disorders Study? Our Eating Disorders Genetics Initiative (EDGI) study has entered its next phase! Building on the success of EDGI1, which saw 3,500 New Zealanders participate, EDGI2 is expanding our understanding of eating disorders even further by allowing us to bring in an…
Read MoreCopy Number Variants (CNVs) and Their Role in Anorexia Nervosa
Copy number variants (CNVs) are changes in DNA where sections are either repeated (duplication) or absent (deletion). These genetic differences can affect how genes work, with larger CNVs potentially causing bigger effects. Rare CNVs might be more important for rarer disorders-like anorexia nervosa-than common CNVs. Anorexia nervosa is a complex psychiatric disorder. Earlier research showed…
Read MoreGenes & Genomes – Insights about our research field
What Are Genes and Why Do They Matter? Every cell in your body contains DNA, a unique code that carries the instructions for how your body works. Within this code are over 20,000 sections called genes. Each gene provides specific instructions for making functional molecules such as proteins, which play essential roles in keeping your…

Read MoreBringing binge eating disorder out of the shadows
Though often in the news, eating disorders are poorly understood. When thinking about eating disorders, people usually think of anorexia nervosa or sometimes bulimia nervosa, but rarely about the most prevalent – binge eating disorder (BED). People affected by BED regularly eat large amounts of food while feeling unable to control their eating. These binges…
Read MoreUsing genetics to understand eating disorders
In May 2023, our Professor Martin Kennedy presented an 8 minute talk on using genetics to understand eating disorders. This talk was inspired by our work with EDGI and prior research. Martin explains that eating disorders are damaging, very poorly understood, and difficult to treat. They can also be strongly driven by genetics. He discusses…
Read MoreThe relationship between night eating syndrome and other eating disorders
Night eating syndrome (NES) was formally recognised as an eating disorder nine years ago, and is characterised by delayed patterns of food intake. More specifically, people affected by NES typically don’t feel like eating earlier in the day, but often eat excessively after dinner (perhaps a quarter of their daily intake) and then regularly wake…
Read MoreWhat is the connection between ADHD and eating disorders?
Attention deficit hyperactivity disorder (ADHD) starts early in life. Common symptoms include struggling to focus on tasks, making mistakes due to inattention, being over-active and fidgety, and being impulsive – interrupting conversations or acting without thinking. Many people are like this sometimes, but for people with ADHD, the symptoms are persistent and interfere significantly with…
