Medical nutrition therapy targeting improvement of metabolic parameters in individuals diagnosed with insulin resistance, through a low-glycemic-load, fiber-rich eating plan.
Indication
- Individuals with elevated HOMA-IR (insulin resistance marker) on laboratory tests
- Prediabetes or impaired fasting glucose (borderline elevated blood sugar)
- Insulin resistance associated with polycystic ovary syndrome (PCOS)
- Metabolic syndrome (waist circumference, blood pressure, lipid disturbances)
- Insulin resistance accompanied by hepatic steatosis (fatty liver)
- Individuals with a family history of type 2 diabetes who require weight management
Preparation
- Recent results of fasting blood glucose, fasting insulin, HbA1c, lipid panel, and liver function tests
- List of medications used (metformin, oral antidiabetics, hormonal therapy)
- A 3-day food diary (with photographs if possible)
- Notes on physical activity habits and sleep patterns
How it's performed
- The dietitian assesses the patient with anthropometric measurements (height, weight, waist circumference, body fat percentage)
- HOMA-IR and other laboratory data are analyzed; a metabolic profile is established
- An individualized plan emphasizing low-glycemic-load, complex carbohydrates and fiber (25-30 g/day) is prepared
- Meal timing, portion control, and carbohydrate distribution (3 main + 2-3 snacks) are arranged
- Behavioral nutrition strategies (mindful eating, hunger-satiety awareness) are taught
- The patient is provided with a written nutrition plan, shopping list, and sample menu
Post-procedure
- First 4 weeks: follow-up every 2 weeks with anthropometric and dietary adherence assessment
- Laboratory follow-up at 8-12 weeks (HOMA-IR, HbA1c, lipid)
- The plan is revised according to the patient's metabolic response and lifestyle
- Multidisciplinary communication with endocrinology or internal medicine physicians is maintained
Risks
- Hypoglycemia (low blood sugar) — especially in those using insulin/sulfonylurea; medication doses must be adjusted with the physician
- Fatigue, headache, or irritability with excessive caloric restriction
- Risk of overlooking protein/sodium restriction in patients with concomitant kidney/liver disease
- Short-term variability in response — due to individual metabolic differences
FAQ
Should carbohydrates be completely eliminated in insulin resistance?
No. Complete elimination of carbohydrates is not recommended; it is essential to choose low-glycemic-load sources such as whole grains, legumes, and vegetables, and to balance portions appropriately.
When will I see results?
Depending on individual metabolism, meaningful improvement in HOMA-IR and anthropometric measurements may be seen at 8-12 weeks; lasting results require long-term lifestyle changes.
Is nutrition alone enough, or is exercise essential?
Combined with nutrition, regular aerobic and resistance exercise significantly improves insulin sensitivity; a combined approach is recommended.
How often should I see the dietitian?
Every 2 weeks at the start, and monthly during the stable phase; the schedule is planned according to the individual's metabolic response.
