Insights
A low-carb diet (LCD) in girls with type 1 diabetes improved glycemic control and reduced insulin needs without adverse effects. This suggests potential benefits for weight management and atherosclerosis prevention.
Area of Science:
- Endocrinology
- Metabolic Disorders
- Pediatric Diabetes
Background:
- Type 1 diabetes management requires careful balancing of diet, insulin, and physical activity.
- Glycemic control is crucial for preventing long-term complications.
- Dietary interventions, such as low-carbohydrate diets (LCDs), are increasingly explored for their impact on diabetes management.
Purpose of the Study:
- To evaluate the short-term benefits and risks of a low-carbohydrate diet (LCD) in girls with type 1 diabetes.
- To assess the impact of LCD on glycemic control and insulin requirements.
Main Methods:
- A prospective randomized cross-over study involving 28 girls with type 1 diabetes.
- Participants were hospitalized for 7-day periods, alternating between an LCD and a regular diet.
- Continuous glucose monitoring (CGM) was used to assess glycemic control throughout the study.
Main Results:
- The low-carbohydrate diet (LCD) was associated with significantly lower carbohydrate intake and reduced rapidly acting insulin doses.
- Morning postprandial, noon postprandial, and evening preprandial blood glucose levels were significantly lower on the LCD.
- No adverse events were reported during the study period.
Conclusions:
- The low-carbohydrate diet (LCD) demonstrated potential for improved glycemic control in girls with type 1 diabetes.
- Lower insulin requirements on LCD may offer advantages for weight control and atherosclerosis prevention.
- LCD appears to be a safe short-term dietary strategy for this population.
Objective:
We conducted the present study to observe potential short-term benefits or risks of low-carb diet (LCD).
Methods:
This is a prospective randomized cross-over study. Type 1 diabetic girls were hospitalized in ternary groups for 7 days and each group randomly started with LCD or regular diet. Continuous glucose monitoring (CGM) was performed between 0 and 168 h.
Results:
Twenty-eight subjects completed the study. Total energy, protein, and fat consumption were high (P < 0.001); carbohydrate consumption and rapidly acting insulin dose were low (P < 0.001 and P = 0.002, respectively) during LCD. Morning postprandial, noon postprandial, and evening preprandial capillary blood sugar levels were lower during LCD (P = 0.013, 0.018, and 0.048, respectively).
Conclusion:
LCD may have the advantage of better glycemic control despite lower insulin dose which is a favorable outcome with regard to weight control and atherosclerosis prevention. No adverse events were observed.

Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
