Are you looking to bulk up and build muscle mass? One of the most critical factors in achieving your goal is consuming the right number of calories. Eating too few calories can hinder muscle growth, while consuming too many can lead to unwanted fat gain. In this article, we’ll delve into the world of calorie intake and explore how many calories you should eat per day to get big.
Understanding Caloric Needs for Muscle Growth
To build muscle, you need to be in a calorie surplus, meaning you consume more calories than your body burns. This surplus provides your body with the necessary energy to build and repair muscle tissue. However, the key is to find the right balance between calorie intake and macronutrient distribution.
Factors Affecting Caloric Needs
Several factors influence your daily caloric needs, including:
- Age: As you get older, your metabolism slows down, and your caloric needs decrease.
- Weight: The more you weigh, the more calories you need to maintain your weight.
- Height: Taller individuals require more calories due to their larger body size.
- Activity level: If you’re highly active, you’ll need more calories to support muscle growth and recovery.
- Goals: Are you looking to bulk up quickly or slowly? Your caloric needs will vary depending on your goals.
Calculating Your Daily Caloric Needs
To calculate your daily caloric needs, you can use the following formula:
- Basal Metabolic Rate (BMR) x activity multiplier = daily caloric needs
Your BMR is the number of calories your body needs to function at rest. You can calculate your BMR using an online calculator or the following formula:
- BMR (men) = 66 + (6.2 x weight in lbs) + (12.7 x height in inches) – (6.8 x age in years)
- BMR (women) = 655 + (4.35 x weight in lbs) + (4.7 x height in inches) – (4.7 x age in years)
Once you have your BMR, multiply it by an activity multiplier based on your activity level:
- Sedentary (little or no exercise): 1.2
- Lightly active (light exercise/sports 1-3 days/week): 1.375
- Moderately active (moderate exercise/sports 3-5 days/week): 1.55
- Very active (hard exercise/sports 6-7 days a week): 1.725
- Extremely active (very hard exercise/sports & physical job or 2x training): 1.9
For example, let’s say you’re a 25-year-old male who weighs 150 lbs, is 5’9″ tall, and has a moderately active lifestyle. Your BMR would be:
- BMR = 66 + (6.2 x 150) + (12.7 x 71) – (6.8 x 25) = 1,987 calories
Your daily caloric needs would be:
- 1,987 x 1.55 = 3,079 calories
Macronutrient Distribution for Muscle Growth
While calorie intake is crucial for muscle growth, macronutrient distribution also plays a significant role. Aim to distribute your daily calories into the following macronutrient ratios:
- Protein: 1.6-2.2 grams per kilogram of body weight (for muscle growth and repair)
- Carbohydrates: 2-3 grams per kilogram of body weight (for energy and muscle recovery)
- Fat: 0.5-1 gram per kilogram of body weight (for hormone production and overall health)
Using the example above, your daily macronutrient intake would be:
- Protein: 150 lbs / 2.2 = 120-150 grams
- Carbohydrates: 150 lbs / 2.5 = 250-375 grams
- Fat: 150 lbs / 0.75 = 35-50 grams
Caloric Surplus for Muscle Growth
To build muscle, you need to be in a calorie surplus. Aim to consume an additional 250-500 calories above your maintenance level. This surplus will provide your body with the necessary energy to build and repair muscle tissue.
Using the example above, your daily caloric intake for muscle growth would be:
- 3,079 (maintenance) + 250-500 (surplus) = 3,329-3,579 calories
Sample Meal Plan for Muscle Growth
Here’s a sample meal plan to help you achieve your daily caloric and macronutrient needs:
| Meal | Calories | Protein | Carbohydrates | Fat |
| — | — | — | — | — |
| Breakfast | 500 | 40g | 60g | 20g |
| Snack | 200 | 20g | 30g | 10g |
| Lunch | 600 | 50g | 80g | 25g |
| Snack | 200 | 20g | 30g | 10g |
| Dinner | 700 | 60g | 100g | 30g |
| Snack (before bed) | 300 | 30g | 40g | 15g |
Total: 3,400 calories, 220g protein, 340g carbohydrates, 110g fat
Conclusion
Building muscle mass requires a combination of proper nutrition, consistent training, and sufficient rest. By calculating your daily caloric needs and distributing your macronutrients accordingly, you’ll be well on your way to achieving your muscle-building goals. Remember to stay patient, as muscle growth takes time and consistency.

By following these tips and staying committed to your training and nutrition plan, you’ll be on your way to building the muscle mass you’ve always wanted.
What is bulking up and how does it relate to calorie intake?
Bulking up refers to the process of intentionally gaining weight and muscle mass through a combination of proper nutrition, consistent training, and sufficient rest. Calorie intake plays a crucial role in bulking up, as it provides the necessary energy for muscle growth and recovery. When you consume more calories than your body burns, the excess energy is stored as muscle mass, allowing you to bulk up.
To bulk up effectively, it’s essential to ensure that you’re consuming a calorie surplus, meaning you’re taking in more calories than your maintenance level. This can be achieved by increasing your daily caloric intake through a balanced diet that includes protein-rich foods, complex carbohydrates, and healthy fats. Additionally, it’s crucial to focus on progressive overload, which involves gradually increasing the weight or resistance you’re lifting over time to challenge your muscles and stimulate growth.
How many calories should I eat per day to bulk up?
The daily caloric intake required to bulk up varies depending on individual factors such as age, weight, height, and activity level. Generally, a safe and sustainable rate of muscle gain is 0.5-1 kg per week, which can be achieved by consuming an additional 250-500 calories above your maintenance level. For example, if your maintenance level is 2,500 calories, you may aim to consume 2,750-3,000 calories per day to bulk up.
However, it’s essential to note that everyone’s nutritional needs are different, and the optimal caloric intake for bulking up may vary from person to person. It’s recommended to consult with a registered dietitian or a qualified healthcare professional to determine your individual caloric needs and develop a personalized nutrition plan that suits your goals and requirements.
What role does protein play in bulking up, and how much protein should I consume?
Protein is a crucial nutrient for muscle growth and repair, making it an essential component of a bulking diet. When you consume enough protein, you provide your muscles with the necessary building blocks to grow and recover from intense training. Aim to consume 1.6-2.2 grams of protein per kilogram of body weight daily, spread across 3-5 main meals and 2-3 snacks.
For example, if you weigh 70 kg, aim to consume 112-154 grams of protein per day. Good sources of protein include lean meats, fish, eggs, dairy products, legumes, and plant-based protein powders. Additionally, consider timing your protein intake to coincide with your workouts, as research suggests that consuming protein within an hour after exercise can help promote muscle recovery and growth.
How important is carbohydrate intake when bulking up?
Carbohydrates provide energy for your workouts and help support muscle growth and recovery. When bulking up, it’s essential to consume complex carbohydrates such as whole grains, fruits, and vegetables, which provide sustained energy and fiber. Aim to consume 2-3 grams of carbohydrates per kilogram of body weight daily, spread across 3-5 main meals and 2-3 snacks.
For example, if you weigh 70 kg, aim to consume 140-210 grams of carbohydrates per day. Additionally, consider timing your carbohydrate intake to coincide with your workouts, as research suggests that consuming carbohydrates within an hour after exercise can help promote muscle recovery and growth. However, be mindful of your overall calorie intake and avoid overconsumption of carbohydrates, which can lead to excessive weight gain.
What is the role of healthy fats in a bulking diet?
Healthy fats are essential for hormone production, brain function, and the absorption of vitamins and minerals. When bulking up, it’s essential to consume healthy fats such as nuts, seeds, avocados, and olive oil, which provide sustained energy and support overall health. Aim to consume 0.5-1 gram of healthy fats per kilogram of body weight daily, spread across 3-5 main meals and 2-3 snacks.
For example, if you weigh 70 kg, aim to consume 35-70 grams of healthy fats per day. Additionally, consider incorporating healthy fats into your meals and snacks to provide sustained energy and support muscle growth and recovery. However, be mindful of your overall calorie intake and avoid overconsumption of healthy fats, which can lead to excessive weight gain.
How often should I eat when bulking up?
When bulking up, it’s essential to eat frequently to provide your muscles with a constant supply of nutrients. Aim to eat 5-6 main meals and 2-3 snacks per day, spaced out every 2-3 hours. This can help keep your muscles fueled and support muscle growth and recovery.
Additionally, consider eating a meal or snack within an hour after your workout, as research suggests that consuming nutrients during this time can help promote muscle recovery and growth. However, be mindful of your overall calorie intake and avoid overeating, which can lead to excessive weight gain. Instead, focus on consuming nutrient-dense foods and drinks that provide sustained energy and support muscle growth and recovery.
How long does it take to see results when bulking up?
