Why Do Some People Struggle to Gain Weight?

Being underweight often comes with challenges that aren’t visible at first glance:

• Lower self-esteem
• Social pressure or body shaming
• Weak immunity
• Frequent tiredness or weakness
• Hair fall and dull skin
• Low muscle mass
• Irregular periods in females
• Slow injury recovery
• Nutrient deficiencies

Just like obesity, being underweight is a health condition and deserves equal support and structured planning.

Understanding Healthy Weight Gain

Gaining weight is not about eating junk food or consuming fried snacks all day. There’s a healthy way to gain weight that focuses on:

• Building lean muscle tissue
• Improving metabolism
• Strengthening digestion
• Boosting hormonal health
• Increasing strength and stamina

A balanced weight gain diet plan focuses on nutritious, calorie-dense meals instead of empty calories.

Ideal healthy gain:
0.5 kg to 1 kg per week

Slow and steady wins, otherwise you gain fat instead of muscle.

Hidden Reasons You’re Not Gaining Weight

1. Fast Metabolism

Some bodies burn calories faster even at rest. This makes weight gain challenging.

What to do

• Increase daily calorie intake by 300–600 calories
• Choose calorie-dense foods: nuts, seeds, paneer, peanut butter
• Add smoothies & shakes
  

2. Poor Appetite

Not feeling hungry enough? That’s a big barrier.

Solutions for low appetite

• Eat small frequent meals
• Sip calorie-rich drinks (milk, shakes)
• Light walk before meals
• Add digestion-boosters: ginger, jeera, lemon water

3. Insufficient Protein

Protein builds muscle. Most underweight people don’t consume enough.

Daily protein goal:
1.2–1.8 g/kg body weight

Example: 60 kg person needs 72–108g protein daily

Best sources: paneer, curd, eggs, milk, tofu, chicken, dals, whey protein.

4. Poor Digestion & Gut Issues

You might be eating plenty, but absorbing very little.

Symptoms:

• Bloating
• Gas
• Diarrhea
• Constipation
• Low appetite

Solutions

• Probiotics: curd, buttermilk
• Ginger, fennel seeds
• Jeera water
• Reduce excessive tea/coffee

5. Thyroid & Hormonal Imbalance

Hyperthyroidism and female hormonal imbalance affect weight.

If you’re losing weight unexpectedly, test for:

• Thyroid
• Vitamin D
• B12
• Iron

6. Stress & Anxiety

Stress increases cortisol, which reduces appetite and burns muscle mass.

Fix stress daily:
Yoga, journaling, meditation, deep breathing, sunlight exposure.

7. Over-Exercising or No Exercise

Cardio burns calories; strength training builds muscle.

Best workout routine:
3–5 weight training sessions per week
Avoid excessive running or HIIT

8. Skipping Sleep

Muscles grow during sleep.

Sleep target: 7–9 hours
