Who Should Consider Weight Reduction?

1. Patients diagnosed with coronary artery disease (CAD)
2. Individuals with heart failure and obesity
3. Post‑angioplasty or post‑surgery patients with elevated BMI
4. People with hypertension or diabetes alongside heart disease
5. Those with high cholesterol or metabolic syndrome
6. Sedentary individuals at risk of cardiac complications

Why Weight Reduction Matters in Heart Disease?

1. Reduces strain on the heart
2. Improves blood pressure and cholesterol levels
3. Helps manage blood sugar in diabetic patients
4. Lowers risk of future cardiac events

Identifying Candidates for Weight Loss Intervention

1. BMI ≥ 25 in patients with existing cardiac issues
2. Waist circumference above recommended levels
3. Inactive lifestyle and poor dietary habits
4. Recurrent chest pain or breathlessness due to weight

The Approach to Weight Reduction in Patients with Heart Disease

Stepwise Approach to Weight Reduction

A structured, safe weight‑loss plan is crucial for patients with heart disease. Here is a step‑by‑step guide combining lifestyle changes and medical management:

1. Step 1: Medical Evaluation
   • Why it matters: Weight loss should never begin without understanding the patient’s current health status.
   • Actions:
     • Full physical examination
     • Check blood pressure, heart rate, and ECG
     • Lab Tests: Lipid profile, HbA1c, liver and kidney function
     • Medication review to ensure compatibility with weight‑loss plans
     • Identify comorbidities: diabetes, sleep apnea, depression
2. Step 2: Nutritional Therapy
   • Goal: Create a calorie deficit while preserving heart health.
   • Action: 
     • Adopt a Mediterranean or DASH diet (see details below)
     • Consult a registered dietitian
     • Portion control using smaller plates
     • Eat slowly and mindfully
     • Track food intake using apps or a food diary
     • Limit salt, added sugar, and unhealthy fats
3. Step 3: Physical Activity
   • Goal: Safely increase energy expenditure
   • Action: 
     • Begin under medical supervision, especially if post‑heart event
     • Start with walking, 10–15 minutes daily, increase gradually
     • Include light resistance training after doctor approval
     • Use wearables or apps to track steps and progress
     • Join cardiac rehabilitation programs if available
4. Step 4: Behavioral & Psychological Support
   • Goal: Address emotional barriers to weight loss
   • Actions: 
     • Screen for depression, anxiety, or emotional eating
     • Refer to psychologist or counselor
     • Consider Cognitive Behavioral Therapy (CBT)
     • Encourage support groups or group therapy
     • Practice stress‑reduction techniques: Yoga, Mindfulness, Breathing Exercises
5. Step 5: Medical Management (Pharmacotherapy)
   • When: Consider if lifestyle changes alone are insufficient after 3–6 months.
   • Actions: 
     • Prescribe anti‑obesity medications only after cardiovascular risk assessment
     • Common options (used with caution):
       • Orlistat – reduces fat absorption
       • GLP‑1 Agonists (e.g., Liraglutide, Semaglutide) – slow gastric emptying and reduce appetite
     • Monitor for side effects and medication interactions
     • Adjust heart medications as weight and metabolism change
6. Step 6: Monitoring & Follow‑Up
   • Set Realistic Weight‑Loss Goals
     • Aim for a gradual weight loss of 0.5 – 1 kg (1–2 lbs) per week
     • Even 5–10% reduction in body weight can significantly improve heart health.
   • Goal: Ensure safety and sustained progress
   • Actions: 
     • Monthly weight and vital‑sign checks
     • Adjust goals and plan based on progress
     • Encourage ongoing lifestyle changes
     • Reassess medications and lab markers every 3–6 months

Mediterranean Diet

1. Overview: A plant‑based eating pattern inspired by the traditional cuisines of countries along the Mediterranean Sea, renowned for heart‑health benefits.
2. Core Components:
   • High intake of vegetables, fruits, whole grains, legumes, and nuts
   • Healthy fats from olive oil, avocados, and seeds
   • Regular consumption of fish and seafood (2–3 times/week)
   • Limited intake of red meat and processed meats
   • Minimal added sugars and refined carbs
   • Use of herbs and spices instead of salt
   • Optional: moderate red‑wine intake (if safe)
3. Health Benefits:
   • Lowers LDL cholesterol and raises HDL
   • Reduces risk of heart disease and stroke
   • Helps control blood sugar levels
   • Encourages sustainable weight loss

DASH Diet (Dietary Approaches to Stop Hypertension)

• Core Components:
  • Emphasis on vegetables, fruits, low‑fat dairy
  • Includes whole grains, lean protein (chicken, fish), beans, and nuts
  • Limits saturated fats, red meat, sugar‑sweetened drinks, and sweets
  • Sodium intake: ≤ 2,300 mg/day (or as low as 1,500 mg/day if needed)
• Health Benefits:
  • Reduces high blood pressure within weeks
  • Supports gradual, healthy weight loss
  • Improves lipid profiles (cholesterol)
  • Lowers risk of stroke, heart failure, and kidney disease

Sample Day (Blend of Mediterranean + DASH)

• Breakfast:
  • Oatmeal with berries and a few almonds
  • Low‑fat milk or plant‑based alternative
• Lunch:
  • Grilled salmon salad with mixed greens, chickpeas, cucumbers, and olive‑oil dressing
