Diabetes could not be esily be separated in type 1 and type 2, there are also less than common types, like LADA, that is a type 1 diabetes that starts in adults and the destruction of beta cells is slower than type 1 in child, or type various MODY types.
Some research has found that people with type 1 and type 2 have common
Classic Type 2 diabetes could be controlled with weight control, exercise, and diet, and of course other types of diabetes are better controlled with the same method.
Unfortunately the informations on correct dieting are a lot misleading, so people are thinking that the problem is sugar and not starches, so a "sane" potato mash or a rice casserole or "alfredo pasta" with margarine are really a bad choiche regarding the calorie and carbohydrate content. The fact that also not so sane foods like margarine or fructose arre advertised as "sane" doesn't help.
