Diabetic Diet – Calorie-Based Food Distribution Chart (Food Exchange Method)

I. Objectives and Significance
Dietary guidance helps patients understand the importance of rational diabetic nutrition, maintain normal body weight, reduce pancreatic β-cell burden, and develop personalized meal plans tailored to individual needs.

Correct metabolic disorders, restore blood glucose and blood lipids to normal or near-normal levels, and alleviate clinical symptoms.
Sustain healthy body weight: reduce calorie intake for obese patients to improve insulin sensitivity via weight loss; increase calorie intake for underweight patients to enhance physical strength and disease resistance.
Alleviate pancreatic β-cell workload, normalize blood glucose, urine glucose and blood lipids, and delay the onset and progression of cardiovascular complications.
Preserve overall health, enabling diabetic patients to perform routine physiological activities and maintain moderate-to-vigorous physical capacity.

II. Target Population

Newly diagnosed type 2 diabetes mellitus patients
Diabetic patients with BMI > 30

III. Nursing Interventions

Educate patients on the significance of rational diabetic diet and core principles of dietary control.
Conduct comprehensive patient assessment; calculate total daily calorie requirement based on height, weight, labor intensity, dietary habits and disease status. Adopt a 1:2:2 calorie distribution ratio for three meals: carbohydrates 55%–75%, protein 10%–20% (≥50% high-quality protein), fat 20%–30%. Formulate individualized diabetic dietary regimens.
Develop three-meal daily menus with patients using the food exchange list based on personal dietary preferences.
Monitor patients’ meal intake and communicate timely with clinical nutrition catering departments.
Collaborate with attending physicians to adjust dietary plans dynamically according to blood glucose fluctuations and laboratory examination indicators.
Arrange timely dietitian consultations for special patients to design customized therapeutic diets.
Encourage in-hospital patients to attend ward-based diabetes education classes to acquire disease knowledge and recognize dietary control importance.
Provide detailed discharge dietary guidance and written instructional materials for patients and family caregivers to follow at home.
Conduct follow-up home visits 1 week after discharge to evaluate dietary compliance, identify inappropriate eating behaviors and provide corrective guidance.

Dietary therapy is the cornerstone of diabetes management. All patients, regardless of disease severity or medication regimen, require long-term dietary modification. Nursing staff shall deliver patient-centered health education to guide scientific rational eating, stabilize blood glucose within target ranges, effectively prevent or delay complications, and improve quality of life for diabetic individuals.
IV. Calculation Formulas and Procedures

1. Calculate Standard Body Weight
   Standard Weight (kg) = Height (cm) − 105
2. Assess Body Constitution via Body Mass Index (BMI)
   BMI Formula: BMI = Weight (kg) ÷ Height² (m) BMI < 18.5: Underweight
   BMI 18.5–23.9: Normal
   BMI 24–27.9: Overweight
   BMI ≥ 28: Obese
3. Calorie Requirement Based on Constitution & Labor Intensity (kcal/kg standard weight/day)
   Note: Adopt light physical labor standard during hospitalization Bedridden: Underweight 20–25; Normal 15–20; Overweight/Obese 15
   Light Physical Labor (teachers, clerks, salespersons): Underweight 35; Normal 30; Overweight/Obese 20–25
   Moderate Physical Labor (students, drivers, physicians): Underweight 40; Normal 35; Overweight/Obese 30
   Heavy Physical Labor (porters, farmers, construction workers): Underweight 45–50; Normal 40; Overweight/Obese 35
4. Calculate Total Daily Calorie Intake
   Total Daily Calories (kcal) = Standard Weight (kg) × Calorie CoefficientThree-Meal Distribution Ratio: Breakfast _ Lunch Dinner ___
