Day-by-Day Weight Gain Strategy

---

1. Calculate Your Caloric Needs

First, find out your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE). Add at least 500–700 extra calories to your TDEE every day to gain weight steadily. Use online calculators or consult a nutritionist.

2. Eat Calorie-Dense Foods Frequently

Focus on high-calorie, nutrient-rich foods rather than just junk food. Aim for 5–6 meals per day instead of 3. Include:

• Healthy fats: Avocados, nuts, seeds, olive oil, peanut butter
• Complex carbs: Brown rice, oats, whole wheat bread, sweet potatoes
• Proteins: Eggs, chicken, fish, tofu, paneer, lentils, beans
• Dairy: Whole milk, cheese, full-fat yogurt
• Fruits: Bananas, mangoes, dates, raisins

3. Drink Your Calories

If eating a lot feels difficult, drink your calories:

• High-calorie smoothies (banana, peanut butter, oats, milk, honey)
• Protein shakes (with whey or plant-based protein)
• Full-fat milk with almonds and honey

Avoid water just before meals—it can reduce your appetite.

---

4. Focus on Protein Intake

Muscle mass = weight gain. Protein is essential for building muscle:

• Eat 1.6 to 2.2 grams of protein per kg of body weight daily.
• Include eggs, chicken, lentils, dairy, and protein powder.
• Have a protein source with every meal.

---

5. Strength Training & Exercise

Yes, exercise is important even when gaining weight!

• Focus on resistance training: push-ups, squats, dumbbells, gym workouts.
• Do 3–4 sessions per week.
• Avoid excessive cardio—it burns calories.

Strength training ensures most of the weight you gain is muscle, not fat.

---

6. Sleep & Recovery

Muscles grow when you rest, not just during workouts.

• Aim for 7–9 hours of sleep per night.
• Take short naps if needed during the day.
• Avoid stress; it affects digestion and muscle recovery.

---

7. Stay Consistent & Monitor Progress

• Track your daily calorie intake with apps like MyFitnessPal.
• Weigh yourself every 2–3 days, preferably in the morning.
• Take body photos and measurements to track visual progress.
