- Diagnosis
- Parkinson’s Disease, Bilateral Knee Osteoarthritis, Overweight
Medical Background
Mr. Ashok Mehra, a 72-year-old retired bank manager, was referred for nutrition counseling due to progressive mobility difficulties associated with Parkinson’s Disease. Having lived with the condition for five years, he was also struggling with excess body weight and chronic knee pain caused by bilateral osteoarthritis. He reported stiffness, slower walking, occasional tremors, and discomfort while climbing stairs. Reduced physical activity had contributed to gradual weight gain, increasing joint stress and limiting his daily activities.
Key Challenges
- Parkinson’s Disease with tremors and slower movement
- Bilateral knee osteoarthritis with chronic joint pain
- Overweight with central obesity (BMI 29.1 kg/m²)
- Reduced mobility, stiffness, and difficulty climbing stairs
- Mild constipation and sluggish bowel habits
- Increased risk of muscle loss (sarcopenia) and functional decline
He consulted DytoClick for structured geriatric medical nutrition therapy and weight management.

Nutritional Assessment
- Energy requirement: 1,600–1,700 kcal/day
- Protein requirement: 85–95 g/day (High quality for muscle preservation)
- Dietary fiber: 25–30 g/day
- Fluid requirement: 2.0–2.2 L/day
- Anti-inflammatory Mediterranean-style meal pattern
Diet Protocol
- Portion-controlled, anti-inflammatory Mediterranean-style meal pattern
- High-quality protein sources to support muscle preservation and functional strength
- Omega-3 fatty acid-rich foods (fatty fish, walnuts, flaxseeds) for joint and neurological support
- Increased dietary fiber and adequate hydration to relieve constipation
- Calcium and vitamin D-rich foods to support bone and joint health
- Medication-aware meal scheduling to optimize levodopa/drug absorption and energy levels
- Soft, easy-to-chew meal options during periods of fatigue
Dietary Objectives
Promote healthy weight reduction
Implement calorie-controlled, nutrient-dense meal plans to reduce joint load and ease knee osteoarthritis pain.
Support neurological and joint health
Incorporate omega-3 fatty acids, antioxidants, and anti-inflammatory foods to support brain and joint function.
Preserve muscle mass and functional strength
Ensure adequate high-quality protein distribution to prevent sarcopenia and maintain independent mobility.
Improve bowel regularity and digestive comfort
Increase soluble and insoluble fiber intake alongside optimal hydration to alleviate chronic constipation.
Optimize meal-medication timing
Structure meal timing around Parkinson’s medication to prevent protein-medication interactions and maintain consistent energy.
Nutrition Intervention
Personalized Geriatric Nutrition Plan
Designed a 1,600–1,700 kcal/day Mediterranean-style anti-inflammatory diet with 85–95 g/day protein, tailored for Parkinson’s and osteoarthritis management.
Anti-Inflammatory and Joint Support
Integrated omega-3 rich sources (walnuts, flaxseeds, fish), calcium, and vitamin D to reduce joint inflammation and support bone density.
Bowel & Hydration Management
Added fiber-rich foods (whole grains, vegetables, fruits) and structured 2–2.2 L/day fluid intake to resolve constipation and improve gut motility.
Medication Timing & Meal Texture Guidance
Structured meal timings around Parkinson’s medications and recommended soft, nutrient-dense preparations during periods of fatigue.
Continuous Monitoring & Practical Guidance
Provided practical Indian meal templates, portion guidance, and ongoing follow-up tracking for steady clinical progress.
