Final answer:
Type 1 diabetes is an autoimmune condition causing lack of insulin production, often found in young individuals and not typically related to obesity; management requires administering insulin.
Step-by-step explanation:
The type of diabetes that results from a lack of insulin production and typically occurs in young individuals with no history of obesity is Type 1 diabetes. Type 1 diabetes is a chronic autoimmune disorder where the body's immune system mistakenly attacks the insulin-producing beta cells in the pancreas. This destruction of beta cells leads to an inability to produce the insulin necessary to regulate blood glucose levels. Individuals with Type 1 diabetes are dependent on externally administered insulin for their survival since their pancreas cannot supply it.
