Struggling with a body that feels “too thin” can be just as taxing as trying to lose weight. If you are currently stuck at 40 kg and wondering how to gain weight from 40 kg to 60 kg, you’ve likely realized that just “eating more” isn’t the magic fix. In an Indian household, the advice often stops at “khana khao” (eat food), but your journey requires a more scientific, balanced approach.
To achieve a 20 kg increase healthily, you must maintain a consistent daily caloric surplus of 300–500 calories above your maintenance level. Focus on high-calorie Indian foods like paneer, ghee, and whole grains while performing light strength training. This ensures you gain muscle mass rather than just body fat, reaching your goal safely over 20–40 weeks.

1. Struggling to move the scale past 40 kg? (The Underweight Reality)
I know how frustrating it feels when your clothes don’t fit and your energy levels are constantly low. In India, being “naturally thin” is often dismissed as a lucky trait, but for many, it means battling a high metabolism or poor nutrient absorption. When you weigh 40 kg as an adult, your Body Mass Index (BMI) is likely below the healthy threshold of 18.5 kg/m2, which can weaken your immune system.
Moreover, the emotional toll is real. You might feel “hidden” in baggy clothes or tired of the constant “weakness” comments from relatives. Let’s simplify this: your body needs more “bricks” (nutrients) to build a stronger structure. However, we aren’t looking for just any weight; we want healthy weight gain for the underweight Indian body.
2. Why reaching 60 kg is about more than just “eating more”
Reaching the 60 kg mark is a significant milestone for your metabolic health. According to the ICMR-NIN, nearly one in five Indian adults is underweight, a condition linked to skeletal muscle wasting. If you want to know how to gain weight from 40 kg to 60 kg, you must understand the “Caloric Surplus.”
The Concept of Caloric Surplus
In simple terms, a caloric surplus means you eat more energy than you burn. For instance, if your body needs 1,800 calories to stay at 40 kg, you should aim for 2,100 to 2,300 calories to grow. Specifically, adding 300 to 500 calories daily is the recommended pace for sustainable growth.
Setting a Realistic Pace
Furthermore, do not expect to gain 20 kg in a month. A healthy rate is about 0.5 kg to 1 kg per week. Consequently, the roadmap to move from 40 kg to 60 kg is a marathon of 24 to 40 weeks. This gradual pace allows your skin and organs to adapt to your new size without stress.

3. Common Myths: Junk food vs. Ghee-laden nutrition
A common mistake many make is thinking that samosas and sugary sweets are the fast track to growth. While these are high in calories, they are “empty calories” that lead to inflammation and abdominal fat. Instead, we must prioritize dense nutrition that supports bone density and muscle repair.
The Magic of Good Fats
I know it’s hard to find time to cook, but adding traditional fats like Ghee to your rotis can change your results. A single tablespoon of Ghee adds roughly 120 calories with almost zero digestive load.2 Similarly, nuts and seeds provide healthy monounsaturated fats that support heart health while adding the energy density needed for how to gain weight from 40 kg to 60 kg goals.
Healthy Weight Gain Substitutions
Moreover, small swaps make a big difference. For example, choose whole milk over toned milk. Replace plain water in your oats with whole milk and add honey. These small adjustments ensure you are getting the “muscle gain diet India” needs without feeling overstuffed.
4. The 40kg to 60kg Roadmap: Strategic Indian Meal Swaps
To increase body weight naturally, your plate must be a balance of proteins, complex carbs, and healthy fats. Let’s look at how to optimize your Indian staples:
| Category | Current Choice | Better “Gainer” Swap | Nutritional Benefit |
| Proteins | Thin Dal | Paneer or Soya Curry | Higher amino acid profile |
| Carbs | Plain Rice | Stuffed Paratha or Pulao | Increases caloric density |
| Fats | Refined Oil | Ghee or Cold-pressed Oil | Healthy fats and better energy |
| Snacks | Biscuits | Peanut Chikki or Makhana | Protein-rich calorie boost |
Protein: Your Body’s Building Blocks
Protein is vital for hypertrophy (muscle growth). For a non-gym audience, paneer, eggs, and legumes like rajma or chana are excellent. Notably, 100g of soybeans contains 36g of protein—more than five eggs! Therefore, including these daily is essential for those wondering how to gain weight from 40 kg to 60 kg.

5. A Typical “Gainer” Day: From Morning Milk to Bedtime Turmeric
Consistency is the secret sauce. If you struggle with a low appetite, eating 5–6 small meals is better than three heavy ones. Here is a routine that fits a busy Indian lifestyle:
- Early Morning: 1 glass of whole milk with 5 soaked almonds and 2 dates.
- Breakfast: 2 Paneer Parathas with a bowl of curd or a banana milkshake.
- Mid-Morning: A handful of roasted peanuts or a fruit smoothie.
- Lunch: 2 Ghee-topped Chapatis, a bowl of Dal, seasonal Sabzi, and a portion of Rice.
- Evening: Peanut butter on whole wheat toast or homemade protein laddus.
- Dinner: High-protein curry (Chicken or Paneer) with Roti and salad.
- Bedtime: Warm milk with Turmeric and Ashwagandha to aid recovery and hormones.
6. Don’t let your hard work turn into fat: The Role of Strength Training
If you only eat and don’t move, the weight you gain might just be fat. To reach a healthy 60 kg, we want to build lean mass. You don’t need a fancy gym; simple home-based exercises like squats, push-ups, or using water bottles as weights can stimulate muscle growth.
In addition, exercise actually improves your appetite. When your muscles work, they signal the brain for more fuel. However, keep cardio activities like running short—around 20 minutes—so you don’t burn off the calories you’re trying to save for growth.

7. Managing Weight Gain with Medical Conditions
Reaching 60 kg requires extra care if you are managing conditions like PCOS, diabetes, or thyroid issues. What this means for your daily routine is choosing “metabolically silent” calories that don’t spike your sugar or hormones.
Weight Gain in PCOS and Diabetes
For individuals with PCOS or diabetes, focus on low-glycemic index (GI) foods. Choose Ragi (finger millet) or Jowar instead of refined wheat. These grains stabilize insulin levels while providing the energy needed to gain 20kg healthy way.
Thyroid and Hypertension Considerations
Furthermore, if you have thyroid issues, ensure you get enough selenium from eggs and nuts. For hypertension, weight gain must be low-sodium. Avoid pickles and papads, and instead use herbs like ginger or lemon to flavor your high-calorie meals.
8. Mistakes that keep you stuck at 40 kg
Sometimes, the scale doesn’t move because of simple habits. For instance, drinking water right before a meal can fill your stomach, leaving no room for food. Instead, sip water 30 minutes after you eat.
Similarly, skipping meals because you are “too busy” is a major setback. If you can’t sit for a meal, have a high-calorie shake. Also, remember that your body grows while you sleep. Lack of rest can keep you stuck at 40 kg because it prevents your muscles from repairing.
9. Consistency is your best supplement
The short answer is that gaining 20 kg is a journey of patience. Aim for a healthy increase and celebrate every 0.5 kg. While it’s hard to stay consistent, your body will eventually adapt to this new, stronger version of yourself.
