Aim:
To provide an overview of the existing literature pertaining to insulin restriction as a disordered eating behaviour in individuals with type 1 diabetes and present a novel maintenance model: The Transdiagnostic Model of Disordered Eating in Type 1 Diabetes.
Method:
A systematic review was conducted of the current literature relevant to insulin restriction and/or omission in the context of disordered eating in type 1 diabetes. A new maintenance model was then developed by incorporating diabetes-specific factors into existing eating disorder models.
Results:
Type 1 diabetes may complicate the development and maintenance of disordered eating behaviour. Diabetes-specific circumstances, including disease diagnosis, insulin management, insulin restriction, and diabetes-related complications, contribute to the maintenance of disordered eating cognitions and behaviours.
Discussion:
The proposed model offers a comprehensive representation of insulin restriction as a disordered eating behaviour in type 1 diabetes. Future research should test the model to further understand the mechanisms underlying disordered eating in type 1 diabetes and inform treatments for this at-risk population.

Diabetes Mellitus: Overview and Type I Subtype
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...
Carbohydrate Metabolism
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
