Most insulin users initially gain weight - 5 to 10 pounds is "average"

But as Pat notes it is because all of a sudden you have more insulin in your system

A common misunderstanding is where "body fat" comes from - it is (created) by extra Insulin and extra Carbs (not eating fat like the media would have you believe)

Now that you are injecting insulin you have "extra" and it's job is to take care of that "extra blood sugar" which is why you needed the insulin in the first place

So if you don't want to gain weight you have to reduce the "excess" - EAT LESS CARBS and there will not be "leftovers" for the insulin to turn into body fat (it has to do something with the excess - when all your cells are "fed" it turns the rest into body fat)

While Insulin can mean your blood sugar won't be high if you eat too many carbs, the solution it is using is turning it into body fat

Don't want to gain weight, then starting insulin treatment should "always" be accompanied by eating "lower carb then you already have been" if you don't want to add the extra pounds

Insulin has 2 jobs @A DiabetesTeam Member.
1) help convert glucose in the cells to energy for daily needs.
2) any excess glucose from carbs, simple carbs (sugars), and complex carbs (carbs), is stored for later use as fat. = weight. Baby steps.

So your solution is simple.
Eliminate all added sugars in food and drink.
Cut your carbs until you attain that balance of a stable weight. Find that carb loading balance. Baby steps.

Cut your carbs and protein a bit more, and you can drop 2-3 pounds a month. Please drop weight slowly. Baby steps.

Does that help you understand the weight gain. Baby steps.
