| Mark - I guess you can read it that way. If that is what the question is then the answer to what a TDD should be is always: whatever it takes to reach your glycemic goals. That is however much insulin it takes to get your glucose levels in the range you and your healthcare provider have set for yourself. That is when all is said and done the only thing that really matters.
Mark of course is right on the money, there are too many factors to say something along the lines of a person who weights X will require Y units of insulin per day as it apply to everyone.
Starting insulin doses are usually based on body weight. For insulinopenic type 1 diabetics often a conservative dose of somewhere around 0.5 units of U/100 insulin per kg per day is used in many protocols. Of course physicians will factor in all the individual factors of the patient when starting insulin. For example, a previously undiagnosed type 1 diabetic in the hospital with DKA will require much more than they will need afterwards.
To get to what you are probably asking, most literature quotes that most type 1 diabetics will eventually require around 0.4 to 1.0 units per kg per day. Diabetics in honeymoon phase of course will require much less and pubertal children may require up to 1.5 units per kg per day.
