What changedAfter 12 Weeks
- Weight increased from 54 kg to 57.5 kg (+3.5 kg healthy gain)
- HbA1c improved significantly from 7.8% to 7.0%
- Fasting blood sugar (FBS) improved from 142 mg/dL to ~118 mg/dL
- Appetite, daily energy levels, and muscle strength improved noticeably
Patient Profile
- Name
- Pavan Joshi
- Age / Gender
- 59 years / Male
- Diagnosis
- Type 2 Diabetes Mellitus with Active Hyperthyroidism & Involuntary Weight Loss
Medical Background
Mr. Pavan Joshi, a 59-year-old male, was referred for nutrition counseling due to uncontrolled blood sugar levels, hyperthyroidism, fatigue, frequent hunger, and significant weight loss. Despite having Type 2 Diabetes, he had lost weight over several months due to increased metabolic demands associated with hyperthyroidism, placing him at risk of malnutrition and muscle loss.
Key Challenges
- Type 2 Diabetes with suboptimal glycemic control (FBS 142 mg/dL, PPBS 228 mg/dL, HbA1c 7.8%)
- Active Hyperthyroidism with increased metabolic demands (TSH 0.08 mIU/L, elevated T3 and T4)
- Involuntary weight loss and muscle depletion (BMI 18.7 kg/m²)
- Increased caloric needs compounded by poor nutritional status
- Persistent fatigue, palpitations, and frequent hunger
- Irregular eating habits and metabolic volatility
He consulted DytoClick for structured nutrition counseling to stabilize glycemic control while reversing muscle depletion.

Nutritional Assessment
- Energy requirement: 2,000–2,200 kcal/day to meet elevated metabolic demand
- Protein requirement: 70–85 g/day for lean tissue repletion
- Dietary approach: Low-GI, nutrient-dense meals
- Meal frequency: Small frequent meals every 2–3 hours
- Carbohydrate strategy: Low-GI complex carbohydrates with regular timing
- Nutrient density: Healthy fats, nuts, and seeds to prevent caloric deficit
Diet Protocol
- High-calorie target of 2,000–2,200 kcal/day tailored to meet increased metabolic demands without causing blood sugar spikes
- Delivered 70–85 g/day of protein from lean and nutrient-dense sources to counteract muscle loss
- Adopted low-glycemic-index (GI), nutrient-dense meals to promote steady glycemic regulation
- Scheduled small, frequent meals every 2–3 hours to address constant hunger and avoid postprandial swings
- Included protein-rich foods, nuts, seeds, and healthy fats to safely increase caloric density
- Encouraged low-GI complex carbohydrates and disciplined meal timing
- Limited refined sugars, sweets, and ultra-processed foods
- Added antioxidant-rich foods to support thyroid health and cellular recovery
Dietary Objectives
Optimize glycemic control & stabilize glucose curves
Enforce low-GI complex carbohydrates, regular meal intervals, and sugar restriction to reduce FBS, PPBS, and HbA1c without hypoglycemia.
Compensate for hypermetabolism & restore healthy weight
Provide 2,000–2,200 kcal/day enriched with healthy fats, nuts, and seeds to meet hyperthyroid energy demands and arrest weight loss.
Preserve and rebuild lean muscle mass
Supply 70–85 g/day of high-quality protein to counteract muscle catabolism and stimulate physical rehabilitation.
Alleviate hyperthyroid symptoms & excessive hunger
Distribute nutrient-dense meals across 2–3 hour intervals to manage constant hunger, alleviate fatigue, and reduce palpitations.
Nutrition Intervention
High-Calorie, Low-GI Nutrition Plan
Formulated a 2,000–2,200 kcal/day meal plan calibrated to supply surplus energy for hyperthyroidism while safeguarding against glycemic spikes.
Protein & Healthy Fat Enhancement
Incorporated lean proteins, nuts, seeds, and healthy fats delivering 70–85 g/day protein to prevent muscle wasting and support weight regain.
Frequent Meal Timing & Portioning
Structured small, frequent meals every 2–3 hours to manage excessive hunger, ensure steady fuel delivery, and prevent digestive strain.
Low-GI Selection & Sugar Elimination
Curtailed refined sugars and processed foods, replacing them with complex carbohydrates to improve glycemic stability.
Thyroid-Supportive Nutrient Integration
Added antioxidant-dense foods and essential micronutrients alongside medical management to alleviate palpitations and fatigue.
