Why Weight Gain is Important for Some People

While many people focus on losing weight, there are those who struggle to gain weight. Whether it’s for muscle building, recovering from an illness, or simply to reach a healthier body weight, gaining weight can be just as challenging as losing it. Being underweight can lead to health issues such as weakened immune systems, osteoporosis, and nutritional deficiencies also it causes low confidence in you. A structured approach to gaining weight is important to ensure that the weight gained is healthy and sustainable.

Note: If you are not sure what is the ideal weight for your body according to your gender, height, and age then you must use our “ideal weight calculator” online tool. This calculator uses different equations to calculate your ideal body weight.

The Role of Calories in Weight Gain

Calories are the energy your body gets from the food and drinks you consume. To gain weight, you need to eat more calories than your body burns. This is called a calorie surplus. The number of extra calories you need depends on your current weight, activity level, goals and time period in which you want to achieve the weight goal.

A safe and effective calorie surplus for most people is around 250 to 500 calories per day above your Total Daily Energy Expenditure (TDEE). This ensures you gain weight steadily without putting too much stress on your body.

What is a Weight Gain Calculator?

A weight gain calculator is designed to help you determine the exact number of calories you need to consume each day to achieve your weight gain goals in a healthy manner. It considers several factors, including your current weight, age, gender, height, activity level, and the amount of weight you want to gain within a specific period.

The calculator is particularly useful because it incorporates your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE) into the equation. BMR is the number of calories your body needs to maintain basic physiological functions at rest, while TDEE is the total number of calories you burn in a day, including all your activities.

Why is a Calorie Surplus Important for Weight Gain?

To gain weight, you need to consume more calories than your body burns. This is known as a calorie surplus. Without a surplus, your body won’t have the extra energy it needs to build muscle or store fat. However, it’s important to maintain a healthy surplus. Consuming too many extra calories can lead to unhealthy fat gain, while too few may not result in any noticeable weight gain at all.

Typically, a healthy and sustainable calorie surplus for weight gain ranges from 250 to 500 calories per day above your TDEE. This allows for a gradual weight gain of about 0.5 to 1 pound (0.2 to 0.45 kg) per week, which is considered a healthy rate. Gaining weight too quickly can lead to fat gain rather than muscle, which is why it’s essential to balance your calorie intake.

Calculating BMR: The Foundation of Your Calorie Needs

The first step in using a weight gain calculator is determining your BMR. The BMR tells you how many calories your body needs just to keep functioning, without any physical activity. Here are the three formulas used to calculate BMR in the weight gain calculator:

  1. Mifflin-St Jeor Equation (Default)
    • For Men:
      BMR = 10 * weight (kg) + 6.25 * height (cm) – 5 * age (years) + 5
    • For Women:
      BMR = 10 * weight (kg) + 6.25 * height (cm) – 5 * age (years) – 161
  2. Revised Harris-Benedict Equation
    • For Men:
      BMR = 88.362 + (13.397 * weight in kg) + (4.799 * height in cm) – (5.677 * age in years)
    • For Women:
      BMR = 447.593 + (9.247 * weight in kg) + (3.098 * height in cm) – (4.330 * age in years)
  3. Katch-McArdle Equation
    This equation is particularly useful if you know your body fat percentage:
    BMR = 370 + (21.6 * lean body mass in kg)

If you don’t want to calculate BMR manually then you can use our online BMR calculator also. Just you have to enter your basic details like gender, height, weight, and boom. Your BMR will be calculated automatically.

How to Calculate TDEE: Understanding Your Daily Calorie Needs

Once you have your BMR, the next step is to calculate your TDEE. TDEE takes into account your activity level to give you a more accurate picture of how many calories you burn in a day. Here’s how you can calculate it:

  • Sedentary (little or no exercise):
    TDEE = BMR * 1.2
  • Lightly active (light exercise/sports 1-3 days/week):
    TDEE = BMR * 1.375
  • Moderately active (moderate exercise/sports 3-5 days/week):
    TDEE = BMR * 1.55
  • Very active (hard exercise/sports 6-7 days a week):
    TDEE = BMR * 1.725
  • Extra active (very hard exercise/physical job & exercise 2x a day):
    TDEE = BMR * 1.9

Wait, you don’t need to do this time-consuming calculation manually. We have the best and most accurate TDEE calculator. Just enter your basic details and hit the calculate button.

Example Calculation for Weight Gain

Let’s suppose you’re a 25-year-old male whose weight is 70 kg, 175 cm tall, and you’re moderately active. Here’s how you would calculate your BMR and TDEE using the Mifflin-St Jeor Equation:

  1. Calculate BMR:
    BMR = 10 * 70 + 6.25 * 175 – 5 * 25 + 5
    BMR = 700 + 1093.75 – 125 + 5 = 1673.75 calories/day
  2. Calculate TDEE:
    Since you’re moderately active, multiply your BMR by 1.55:
    TDEE = 1673.75 * 1.55 = 2594.31 calories/day
  3. Determine Calorie Surplus:
    If you want to gain weight at a healthy rate, add a surplus of 300 calories:
    Daily Calorie Intake = 2594.31 + 300 = 2894.31 calories/day

This means you should aim to consume around 2894 calories per day to gradually gain weight.

How to Calculate Calorie Required for Weight Gain in a Specific Time

When you have a specific weight gain goal and a time frame in mind, calculating the daily calorie surplus is important. Let’s break it down step by step:

  1. Determine Your Calorie Surplus:
    • First, decide how much weight you want to gain. For example, let’s say you want to gain 5 kg.
    • Since 1 kg of weight is approximately equal to 7700 calories, gaining 5 kg would require a total surplus of 38500 calories. (5 kg multiplied by 7700 calories)
  2. Choose Your Time Frame:
    • Decide over how many days you want to achieve this weight gain. For example, let’s say you want to gain 5 kg in 60 days.
  3. Calculate Daily Calorie Surplus:
    • To find out how many extra calories you need per day, divide the total calorie surplus by the number of days.
    • For example, 38500 calories divided by 60 days equals approximately 641.67 calories per day.
  4. Add to Your Daily Calorie Needs:
    • Finally, add this daily surplus to your Total Daily Energy Expenditure (TDEE) to find out how many calories you should consume each day to meet your weight gain goal.

So, if your TDEE is 2500 calories, you would need to consume approximately 3142 calories per day (2500 plus 642) to gain 5 kg in 60 days.

Why Use Multiple Equations?

Different people may have different body compositions, activity levels, and metabolic rates. By using three different equations—Mifflin-St Jeor, Revised Harris-Benedict, and Katch-McArdle—you can get a more accurate estimate of your calorie needs. For most people, the Mifflin-St Jeor Equation is a reliable choice, which is why it’s set as the default in the weight gain calculator.

Practical Tips for Healthy Weight Gain

  1. Choose Healthy Foods: Instead of eating junk food, focus on foods that are good for you, like lean meats, whole grains, nuts, seeds, and vegetables. These foods give your body the energy it needs.
  2. Build Muscle: Gaining weight isn’t just about adding fat; it’s also about building muscle. Try to include exercises that strengthen your muscles to turn the extra calories you eat into muscle.
  3. Eat More Often: If big meals are too much, try eating smaller meals more often throughout the day. This makes it easier to eat more without feeling too full.
  4. Track Your Progress: Keep an eye on your weight gain. If you’re not gaining weight, you might need to eat a little more each day.

Some more tips you must follow to healthy weight gain:

Importance of Hydration in Weight Gain

Staying hydrated is just as important when trying to gain weight as it is for losing weight. Water helps your body process the extra calories and nutrients you’re consuming. Drinking enough water supports digestion, helps transport nutrients to your muscles, and keeps you energized for your workouts. Aim to drink at least 8-10 glasses of water a day, and more if you’re active.

Smart Snacking for Weight Gain

Snacking is a great way to add extra calories to your diet without overwhelming your main meals. Choose snacks that are high in both calories and nutrients, like peanut butter on whole grain toast, yogurt with granola, or trail mix with nuts and dried fruits. These snacks are easy to prepare and carry around, making it simple to increase your calorie intake throughout the day.

The Role of Protein in Weight Gain

Protein is essential for building muscle, which is a key part of healthy weight gain. Make sure you’re getting enough protein by including foods like eggs, chicken, fish, beans, and dairy products in your diet. A good rule of thumb is to aim for about 1.2 to 1.5 grams of protein per kilogram of your body weight. For example, if you weigh 60 kg, you should aim for 72 to 90 grams of protein daily.

Meal Planning for Weight Gain

Planning your meals ahead of time can help you stay on track with your calorie goals. Make a weekly meal plan that includes three main meals and 2-3 snacks each day. Prepare your meals in advance so that you always have something nutritious and calorie-dense on hand. This will make it easier to avoid skipping meals or resorting to unhealthy fast food.

Getting Enough Sleep

Sleep plays an important role in weight gain. When you’re well-rested, your body is better able to repair and build muscle, which is important when you’re trying to gain weight. Aim for 7-9 hours of sleep each night to give your body the rest it needs to grow stronger and healthier.

Overcoming Common Challenges

Gaining weight can be challenging, especially if you have a fast metabolism or a busy lifestyle. It’s important to be patient and consistent. If you find it difficult to eat enough during the day, try setting reminders to eat or drinking calorie-rich smoothies between meals. Remember that gaining weight takes time, so don’t get discouraged if you don’t see immediate results.

Supplements for Weight Gain

While it’s best to get most of your nutrients from whole foods, supplements can be helpful if you’re struggling to meet your calorie and protein goals. Protein powders, weight gain shakes, and other supplements can be convenient ways to increase your intake of calories and nutrients. However, it’s important to choose supplements that are safe and effective. Talk to a healthcare provider or a nutritionist before starting any new supplements.

Listening to Your Body

Lastly, it’s important to listen to your body throughout your weight gain journey. Pay attention to how you feel after eating certain foods or doing specific exercises. Your body will give you signals when it’s time to rest, eat, or increase your workout intensity. By tuning in to these signals, you can make adjustments to your plan and ensure that you’re gaining weight in a healthy and sustainable way.

Conclusion

Gaining weight in a healthy way is all about balance and patience. It’s not just about eating more but eating the right kinds of food that give your body the nutrients it needs to grow stronger and healthier. A weight gain calculator is a valuable tool to help you understand how many calories you need each day to reach your weight gain goals. Similarly, a calorie surplus calculator can guide you in determining the right amount of extra calories to consume daily for steady and healthy weight gain.

Remember to focus on nutrient-rich foods like lean meats, whole grains, and vegetables. Don’t forget to include strength training in your routine, as it helps turn those extra calories into muscle, not just fat. Using a weight gain calculator alongside a calorie surplus calculator can make it easier to plan your meals and ensure you’re on track with your weight gain journey. Eating smaller, frequent meals can also make it easier to increase your calorie intake without feeling too full.

Keep track of your progress with the help of a weight gain calculator or calorie surplus calculator. If you’re not gaining weight as expected, adjust your calorie intake based on the results. Achieving your weight gain goal takes time, but with the right approach, these tools, and a bit of determination, you can reach it in a healthy and sustainable way. Stick to your plan, listen to your body, and enjoy the journey to a healthier you.
