The answer is simple. Just bring some simple changes in your diet and normal daily routine. Eat healthy food, drink a lot of water, and do daily physical exercises. 

Fat Vs. Muscle Weight

Fats and muscles both are part of our body and are equally essential. These both also take part in our weight gain. But the difference is that they both increase the weight in different ways. If we discuss fats vs muscle weight then we will come to know that muscles weigh more than that of fats. Muscles are made up of tendons that are compactly bound to each other forming a dense mass. Fats are made up of droplets of fats that are loosely connected.

They leave spaces between them so they are less dense. In this way, fats will cover more area than that of muscles. So if you are increasing weight in a healthy way actually you are increasing your muscle. When muscle weight increases it will not swell your body but the weight will increase. Fats along with gaining weight will swell the body too. 

How Many Calories In One Pound Of Fat?

Fats are easy to store and contain a large number of calories. One pound of fats contains about 4000 calories. So burning a single gram of fats will give about 9 calories. 

How Many Calories In One Pound Of Muscle?

Muscles require more energy and calories to build up. You have to take so many extra calories to build your muscles. One pound of muscle contains about 2500 to 2800 extra calories for building. 

What Weighs More, Muscle Or Fat?

Muscles are dense substance so they occupy less space.  The density of fats is very less so it occupies more space. One pound of muscle will be smaller in size as compared to 1 pound of fats.

Muscles take 18 percent less space than that of fats. So if we say what weighs more, muscle or fat then the answer will be muscle. If you are building your muscles actually you are increasing your weight. If you are eating too much to increase your fats then you are making your body swell. 

Can You Build Muscle And Lose Fat At The Same Time?

It seems impossible to build muscles and lose fats at the same time. This is because for building muscles you need extra calories and for losing fats you have to decrease your caloric intake. But some trainers claim that it is possible. So the question arises how can you build muscle and lose fats at the same time?

For this, you have to low your calorie intake. Start consuming more proteins by doing a keto diet or in a normal diet. This protein will help in muscle building. And the body will take the required calories by burning the deposit of fats in the body.

Determining Your Weight Gain Calorie Needs

A normal man needs 2500 calories and female needs 2000 calories a day. If you are not taking these required calories automatically you will lose weight. Now the question arises here that how many calories do I need to gain weight. You can find your answer by determining your weight gain calorie needs.

Check out how many calories are you gaining a day. If they are less than required then add remaining calories in your diet. 2500 to 2800 calories are required to build one pound of muscle. So divide these calories and add them too in the diet. You can use online calculators to detect the exact amount of needed calories. 

Step 1: Determine Your Maintenance Calories

If you are healthy and your weight is in the normal range then you don’t need to lose or gain weight. But maintenance of weight is very necessary. As you are concern about how many calories do I need to gain weight? In the same way knowledge about calories, maintenance is also very important. You can determine your maintenance calories by the following method. 

  • If you are a woman then multiply weight (in lbs.) with 10
  • And if you are a man then multiply weight with 11
  • Add the answer in the category of your physical activity. 
  • If you don’t do any physical activity, then add 1 in answer. 
  • You are doing 1 to 3 times a week? Then add 1.1.
  • For people doing activity 2 or more days in a week add 1.2.
  • Add 1.4 if doing exercise 3 or more days a day.
  • And if you are doing proper workout 2 times a day then add 1.6 in your answer.
  • The resultant answer will be your required calories. 

Step 2: Add Your Calorie Surplus

For an underweight person, it is very important to know how many calories do I need to gain weight. If your calorie intake is low then add your calorie surplus. For a normal person who is struggling for weight gain, adding 500 calories a day is enough.

Or you can add 10 percent extra than the required calories. But this calculation will not be the same for everyone. As everybody has different health conditions and daily activities. For a beginner trainer, it is easy to gain muscle. And if you are very skinny you will need more calories to gain weight and build muscles. So the conclusion is that a lean person will require more calories than a comparatively trained and normal person. 

Step 3: Calculate Your Macros

Macros are actually macronutrients including carbohydrates, proteins, and fats the body needs. So for know how many calories do I need to gain weight it is important to calculate your macros. If you know about your calorie need according to the body then it is easy to calculate macros. If you want to gain weight then you have to make a correct ratio of macros in the diet. 

You have to add about 1 to 1.5 grams of protein for each pound of your body. 

Fats contain the maximum amount of calories. The body takes about 30 percent of calories from the fats so adjust the fats level accordingly. 

Now check how many calories are remaining from your need. Complete those from obtaining carbohydrates.
