Brief Answer:
Carb ratio

Detailed Answer:
Normally when we recommend Carb ratio calculation, it is assumed that you use rapid acting insulin like Lispro( Humalog) or Aspart ( novorapid). The calculation may go wrong if you are using Actrapid,

Usually 500 / total daily insulin dose is the formula used.
For example, If you are currently using totally 50 units of Insulin per day, then 500 / 50 = 10
This means you need 1 unit short acting insulin before meal to cover for 10 gram carbohydrate,

For Insulin sensitivity factor, you need to divide 1500 by total daily insulin dose.
For example, if your total daily insulin dose is 50 units, 1500/50 = 30
This means, you need 1 unit insulin to reduce 30 mg glucose ( 1 : 30)
Suppose if your glucose is 200 mg and you want to reduce to 120 mg.

Then (200-120) divided by 30 = 2.6 units . This means you need 2.6 units extra insulin ( in addition to your regular dose of insulin based on Carbohydrate ratio)

The above example is based on a total daily insulin dose use of 50 units. The calculation will change based on your daily dose of Insulin.


So you need to sit with an expert dietician and diabetes educator to calculate and learn this as it is a complex subject, You will need to learn how to assess carbohydrate content of your food. Roughly one chappathi has 15 gram carbohydarte
