The Korean Diabetes Association (KDA) has released its updated 2025 Clinical Practice Guidelines for Diabetes Management in Korea. This 9th edition reflects the latest scientific evidence and provides practical, patient-centered approaches tailored to Korean clinical settings.
Diet + physical activity is the most effective approach to prevent type 2 diabetes
Long-term studies show reductions in all-cause and cardiovascular mortality
⚖️ Weight Management
Goal: ≥5% weight loss for overweight or obese adults with T2DM
Even modest weight loss improves outcomes
🩸 Self-Monitoring of Blood Glucose (SMBG)
Individualized timing and frequency based on patient profile
Postprandial glucose strongly correlates with HbA1c
Fasting glucose more influential in those with uncontrolled diabetes
🥦 Evidence-Based Diet Patterns
✅ Mediterranean, Vegetarian, Low-fat, and DASH diets are all acceptable if sustainable and culturally appropriate
✅ Intermittent Fasting (IF): Not recommended for children <12, adults >70, underweight individuals, pregnant or breastfeeding women
✅ Carbohydrate control: Should be tailored based on treatment goals
✅ Dietary fiber: At least 25g/day recommended (≥400g of vegetables & fruits)
✅ Limit sugar-sweetened beverages (SSBs) due to links with obesity and CVD
✅ Fat quality matters: Replace saturated/trans fats with unsaturated fats from whole foods
🚫 Supplements of unsaturated fats have not shown consistent benefit
✅ Sodium: Keep <2,300mg/day
✅ Protein intake for diabetic kidney disease: Avoid both excessive and overly restrictive intake (not below 0.8 g/kg/day)
🧾 Other Key Points
🍷 Alcohol
Avoid if possible—may increase risk of hypoglycemia and glycemic variability
🥤 Hypoglycemia Management
15–20g of glucose (e.g., tablets or juice) typically raises glucose by 45–60 mg/dL
Follow up with a snack or meal to prevent recurrence
🤰 Pregnancy-Specific Recommendations
Avoid excessive carb restriction due to risk of increased fat intake and insulin resistance
Glycemic targets should approach those of healthy pregnancies to reduce perinatal complications
👵 Special Considerations for Older Adults
Consider cognitive status, fall risk, and polypharmacy
HbA1c target can be relaxed (up to 7.5–8.5%) depending on frailty and comorbidities
Emphasis on adequate protein intake to prevent malnutrition and sarcopenia
