Flexible Insulin Therapy (FIT) is a different way of thinking about your diabetes care. FIT allows you to adjust the timing and amount of insulin to meet your needs.
For example, you may correct your meal-time bolus insulin doses up or down to reflect such things as 1) your current blood glucose level, 2) the carbohydrates you plan to eat, and 3) the exercise that you plan to do.
Flexible insulin therapy is possible because today's rapid-acting insulins are injected at the exact time you eat, not 30 minutes before. Since you inject right at mealtime, you can make spontaneous food choices at a meal, then adjust the insulin dose to reflect the grams of carb that you actually eat.
Some people use the names 'Flexible Insulin Therapy' and 'Intensive Insulin Therapy' to mean the same thing.
