How Many Calories for a Skinny Guy to Gain Weight: Demystifying the Magic Number

How Many Calories for a Skinny Guy to Gain Weight?


For individuals struggling to gain weight, understanding their energy requirements is crucial. Skinny guys often face challenges when trying to add mass to their bodies. One key factor in achieving weight gain is consuming enough calories. In this article, we will explore how many calories a skinny guy needs to consume in order to successfully gain weight.

Determining Calorie Needs

To determine the appropriate calorie intake for weight gain, various factors need to be considered. These factors include age, current weight, height, activity level, and metabolism. Each person has unique characteristics that play a role in determining their calorie requirements.

Calculating Calorie Needs

A commonly used method to calculate calorie needs for weight gain is to multiply your bodyweight in pounds by a specific factor. This factor depends on your activity level. The formula is as follows:

Calorie Needs = Bodyweight (in pounds) x Activity Factor

Here are the activity factors for different activity levels:

– Sedentary (little or no exercise): 14-16
– Lightly Active (light exercise or sports 1-3 days a week): 16-18
– Moderately Active (moderate exercise or sports 3-5 days a week): 18-20
– Very Active (hard exercise or sports 6-7 days a week): 20+

For example, if you weigh 150 pounds and have a sedentary lifestyle, your estimated calorie needs would be:

Calorie Needs = 150 x 14-16 = 2100-2400 calories per day

Increasing Caloric Surplus

To gain weight, you need to create a caloric surplus. This means consuming more calories than your body needs to maintain its current weight. To steadily gain weight, aim for a surplus of 250-500 calories per day. This surplus will provide the necessary energy for your body to build muscle mass.

Choosing the Right Foods

Not all calories are created equal. It is essential to choose nutrient-dense foods to support overall health and maximize weight gain. Include a variety of lean proteins, healthy fats, complex carbohydrates, fruits, and vegetables in your diet.

Protein is particularly important for muscle growth. Foods such as chicken, fish, lean meats, eggs, and plant-based protein sources like beans and lentils should be included in your meals. Healthy fats like avocados, nuts, and olive oil can provide the extra calories needed.

Meal Planning

To reach your calorie goals, it is crucial to plan your meals and snacks. Distribute your calorie intake throughout the day by having three main meals and two to three high-calorie snacks in between. Use portion sizes that are appropriate for your needs and include a variety of food groups in each meal.

Monitoring Progress

Keep track of your weight and monitor your progress regularly. If you are not seeing the desired weight gain, consider increasing your daily calorie intake gradually. It may take some time to find the right balance for your body.


For a skinny guy to gain weight, consuming enough calories is essential. Calculating your individual calorie needs, creating a caloric surplus, and choosing nutrient-dense foods will support your weight gain journey. Remember to monitor your progress and adjust your calorie intake accordingly. With patience and perseverance, you can achieve your weight gain goals and improve your overall well-being.


1. Can I gain weight by consuming any type of calories?

No, not all calories contribute equally to weight gain. It is important to focus on consuming nutrient-dense foods that provide the necessary macronutrients and micronutrients for healthy weight gain.

2. Should I rely solely on increasing my calorie intake to gain weight?

While increasing your calorie intake is crucial for weight gain, it is also important to engage in strength training exercises. This will help promote muscle growth and prevent excessive fat gain.

3. How long will it take to see noticeable weight gain?

The time it takes to see noticeable weight gain varies from person to person. It depends on factors such as genetics, metabolism, and consistency in following a calorie surplus diet. It may take several weeks or even months to see significant changes.
