Warsaw Method Results
Step 1: Calculate Calories
Fat calories: 0 g × 9 = 0 kcal
Protein calories: 0 g × 4 = 0 kcal
Total calories: 0 kcal
Step 2: Fat-Protein Units (FPU)
FPU = 0 kcal ÷ 100
FPU = 0.0
Step 3: Carb Equivalent
Carb equivalent = 0 kcal ÷ 10
Carb equivalent = 0.0 g
Step 4: Insulin Dose
Insulin = 0.0 g ÷ 15
Insulin = 0.0 units
Example Calculation
High Fat-Protein Meal Example
Fat content: 10g
Protein content: 20g
Insulin-to-carb ratio: 15 g/unit
Warsaw Method Calculation
Step 1: Total calories = (10g × 9) + (20g × 4) = 90 + 80 = 170 kcal
Step 2: FPU = 170 kcal ÷ 100 = 1.7 FPU
Step 3: Carb equivalent = 170 kcal ÷ 10 = 17g
Step 4: Insulin dose = 17g ÷ 15 g/unit = 1.1 units
Extended bolus: 3 hours (for 1.7 FPU)

Understanding the Warsaw Method
What is the Warsaw Method?
The Warsaw Method is an advanced diabetes management technique developed by the Warsaw School in Poland. It accounts for the glycemic impact of fat and protein in meals, which traditional carbohydrate counting often overlooks.
Why Fat and Protein Matter
- •Fat slows gastric emptying, causing delayed glucose absorption
- •Protein can be converted to glucose through gluconeogenesis
- •High fat/protein meals can cause late-onset glucose spikes
- •Standard carb counting may underestimate insulin needs
Fat-Protein Units (FPU)
1 FPU = 100 kcal from fat and protein
FPUs provide a standardized way to quantify the glycemic impact of fat and protein, similar to how carbohydrate counting quantifies the impact of carbohydrates.
Dual-Wave Bolus
The Warsaw Method works best with insulin pumps that support dual-wave (extended) boluses, delivering part of the insulin immediately and the remainder over several hours to match the delayed glucose release from fat and protein.
Clinical Evidence
Research Foundation
Developed through nationwide studies in Poland with extensive use in children under 7 years old with Type 1 diabetes.
Proven Benefits
Demonstrated reduction in post-meal glucose spikes and decreased incidence of diabetic ketoacidosis.
Implementation Tips
Start Gradually
Begin with high fat/protein meals to see the most benefit
Monitor Closely
Track post-meal glucose for 4-8 hours to assess effectiveness
Work with Team
Collaborate with diabetes educator and endocrinologist
Individual Adjustments
Fine-tune based on personal response patterns
