I'm on 69 units slow and 17 fast insulin, exercise a lot but do not lose any weight. want to lower insulin, will speak to doc, what levels to aim for?

Proper insulin dosin: exercise only leads to a 3-5% total body weight loss which isnt that much. Lowering insulin dose is not the trick to losing weight. As one loses weight they will need a lower insulin dose. The key to being a diabetic and losing weight is the reduction in carbohydrate and calorie intake. The Insulin dose is also a product of carbohydrate intake. The more carbs you eat the more insulin you need
