5. You might have diabetes
If diabetes is left untreated, it is possible to have a condition called diabetic ketoacidosis. This means that the body doesn’t have enough insulin, so the body begins to break down the fat you store. This means you’ll lose some weight but it also means that ketones are built in the body, resulting in a charge in your natural body odor.
The smell is similar to the smell created when a person switches to a very low-carbohydrate diet.
