Insulin- dependent diabetes mellitus
(Type-1) – usually, this type of diabetes affects children or adolescents. There is little or no production of insulin.
If you have type 1 diabetes, weight gain may occur once you start taking insulin.
Losing weight may require fine-tuning your calorie and carbohydrate intake and insulin dose.
People with type 1 diabetes can also develop insulin resistance, and in that situation, would benefit from weight loss to help them need less insulin.
