The study involved 31 women and 17 men with type1 diabetes
aged about 52 years and suffering from type1 diabetes for an average of 24
years and whose HbA1c levels were greater than 6.1%.
The participants attended a dietary educational course for
a day, where they had been instructed to follow a diet with very less carbs and
to restrict their daily carbohydrate intake to less than 75 grams along with
appropriate reduction in insulin dosages. This was followed by 2-3 hours
session every week for the following four weeks.
The researchers evaluated the
long-term adherence to such diets among the participants for four years by assessing
their HbA1c levels on a yearly basis and comparing it with the values recorded
3 months after starting the diet plan.
The analysts found a significant reduction in HbA1c
levels in patients who had strictly followed the recommended diet. And also
their insulin dosage had reduced from 23 IU to 13 IU by the end of one year.
This reduction in HbA1c levels corresponds to a 40% decrease in risk for heart
Hyperglycemia damages the organ
tissues at an alarming speed and predisposes the patients to numerous health
complications. The study showed that with controlled carbohydrate intake it is
possible to keep the health complications like retinopathy and neuropathy at
The experts noted a decrease in cholesterol to HDL ratio
thus reducing the patients' risk for heart attack by 20%.
The researchers thus concluded
that the proposed diet is aimed at lowering the HbA1c levels by lowering the
daily carbohydrate and not reducing the fat and protein levels and such
educational programs might benefit nearly 50% of them in regulating their blood
glucose levels through diet.
