Creating A Calorie Surplus For Muscle Gain

Gaining muscle requires more than going to the gym and lifting weights. In order to get results from your workouts, you need to be in a calorie surplus.

But finding your calorie surplus for muscle gain is sometimes easier said than done. Because your ideal energy intake depends on several factors.

In this article, Iā€™m going to teach you how to find your optimal calorie target to build muscle without gaining excess fat. And you can even try my free calorie surplus calculator.

Calorie Surplus Q&A

Before we dive into the calculations, let me answer a few common calorie surplus questions.

What Is A Calorie Surplus?

A calorie surplus is simply eating more calories than you burn. By doing this, you give your body more energy than it needs. And that leftover energy can be used to build new tissue like muscle.

Calories In > Calories Out = Calorie Surplus

Calorie Surplus

You’ve probably heard of a surplus in the context of business. Basically, it means spending less money than you have in your budget. When that happens you can spend the extra money on something else to use up your budget.

Oscar explains the concept of a surplus to Michael in simple terms… but he’s not quite grasping it yet. šŸ˜‚

In the example above, Michael eventually comes to realize he can spend the budget surplus. And he has to make a big decision about how to spend it.

Similarly, your body can use a calorie surplus in a couple of different ways. 

How Does A Calorie Surplus Help You Gain Muscle?

Keeping with the office analogy, Michael would be wise to spend the surplus on a replacement copier or new desk chairs. Both of which are worn out and need to be replaced.

In the same way, resistance training breaks down your muscles which means they’re in need of repair. So your body is likely to use the energy surplus to build your muscles bigger and stronger.

Unfortunately, Michael has another option – he can keep the surplus and receive a bonus check. Likewise, your body can keep the extra energy and store it as fat.

Will A Calorie Surplus Make You Gain Fat?

It’s absolutely possible to gain fat when you eat a surplus of calories. In fact, this is your body’s default option! Because it wants to save that excess energy for when food might not be available.

However, keep in mind that your body will use the surplus to build muscle if you give it a good enough reason to do so. This is why weight training is so important.

In addition, fat gain can happen if your calorie surplus is too large. When you eat way too much, your body has enough energy to build new muscle and store fat.

How Big Should Your Calorie Surplus Be?

The magnitude of your calorie surplus depends on your body type and fitness goals. Typically your surplus will be anywhere from 5 to 25% more calories than you burn. We’ll get into this more below.

First, it’s important to understand that people who have a hard time gaining weight (ectomorphs) can usually get away with a larger surplus. While people who gain weight easily (endomorphs) should stick with the minimum surplus needed to gain weight.

In addition, you need to think about your goals. Do you want to maximize muscle gain at the expense of gaining some fat (bulking)? Or would you rather minimize fat gain with sub-maximal muscle gain (lean bulk)?


Phases Of Muscle Gain

With your goal in mind, the next step is to calculate your calorie intake.

How To Calculate A Calorie Surplus

In order to calculate your calorie surplus, you first have to know how many calories you burn. Also known as total daily energy expenditure (TDEE).

TDEE is made up of calories burned through your basal metabolic rate (BMR), normal activities like walking around, and any additional exercise.

You can calculate your BMR based on your body composition (I always adjust for your body type too). While the number of calories you burn through physical activity simply depends on the intensity and duration of the activity.

Once you know how many calories you burn, the next step is calculating your calorie surplus based on your fitness goals.

To maximize muscle gain, shoot for a 15 to 25% surplus. Simply multiply your daily calories burned by 1.15 to 1.25.

As an example, Steve burns 2,400 calories per day, his goal is bulking, and he’s a hardgainer. So he’s aiming for a 25% calorie surplus.

Steve’s calorie intake for bulking: 2,400 x 1.25 = 3,000 calories per day

Calorie Surplus For Bulking

Now let’s say your goal is to gain muscle but minimize fat gain. Then your calorie surplus should be smaller.

For lean bulking, target a 5 to 15% surplus. Again, just multiply your calories burned by 1.05 to 1.15.

For example, Sarah burns 2,000 calories per day, she has an endo/meso body type, and her goal is lean bulking. So she’s aiming for a 5% surplus.

Sarah’s calorie intake for lean bulking: 2,000 x 1.05 = 2,100 calories per day

Calorie Surplus For Lean Bulk

This calculation is easy when you know your daily energy expenditure. But finding your TDEE isn’t always easy to do on your own.

Not to mention, your target changes with your daily activity level. That’s why I created a calorie surplus calculator that finds your surplus for days you workout and days you take it easy.

Calorie Surplus Diet Tips

To get the most out of your diet, you need to know about all 4 pieces of the nutrition puzzle. Those pieces are calories, food choices, macros, and meal timing.

calorie surplus bodybuilding nutrition

My simple nutrition framework = 50% calories, 30% foods, 10% macros, and 10% meal timing.

1. Calories

Just to hammer it home, the reason calories are so important is that they’re like your energy budget. If you use more energy than you have available, you’re in a deficit. And you won’t have any energy left over to build new muscle.

Without this energy reserve, the other 3 pieces of the puzzle don’t matter as much. So step one is getting your calorie intake right. Which you can do using the calculations above or the calorie surplus calculator.

2. Food Choices

Once you have your calories correct, the next biggest piece of the puzzle is the foods that supply the calories. Choosing whole foods is the best way to ensure you get all the nutrients you need to build muscle.

You may be tempted to use junk foods to hit your calorie surplus target – this is called dirty bulking. But, believe me, that choice will lead to excess fat gain.

The best rule of thumb is to stick with healthy foods 90% of the time in order to optimize muscle gain and overall health.

3. Macros

Next up is macros; protein, carbs, and fat. On any muscle gain diet, you’re going to need high protein.

The general rule is 1 gram of protein per pound of body weight. But this rule doesn’t work well if you’re lean or overweight. So I recommend aiming for about 30% of your calories from protein.

To create your calorie surplus, you’re also going to need a lot of carbs. But you don’t want to eat too many carbs, or you’ll be more likely to store them as fat. On days you workout, get about 40-50% of your calories from carbs. This target will be lower on days you don’t work out.

Then you just fill in the gap with dietary fat. From the numbers above, that means 20-30% of your calories from fat.

4. Meal Timing

Last, is when you eat your meals throughout the day. And this piece really depends on your schedule.

Specifically, the time of day you workout. Because the distribution of calories and macros shifts more heavily towards your workout.

For example, if you workout in the evening, more of your calories and carbs will be at night. And vice versa if you workout in the morning.

The reason for this is to provide energy for your workouts, replenish the energy you use, and control your blood sugar throughout the day.

Muscle Building Workout Routine

Of course, there’s more to muscle gain than just your diet. You also have to dial in your workouts in order to really transform your body.

Like nutrition, there are 4 factors involved in assembling an ideal workout routine; rep range, rest periods, number of sets, and exercise selection.

1. Low to Medium Rep Range

Getting bigger and getting stronger go hand in hand. Low (1-5) reps are best to get stronger. While medium (6-12) reps are best for growth.

Therefore, I recommend you use a weight you can lift for 5-10 reps for most of your sets during a muscle gain phase.

2. Longer Rest Between Sets

Those heavy sets will get your heart pumping. And you need to let your heart rate come down before attempting the next set.

Otherwise, it will be your cardiovascular system that gets tired before your muscles. So take at least 90 seconds between sets and up to 2 or 3 minutes if needed.

3. Less Volume, More Intensity

Taking longer rests allows you to exert maximum effort on every set. In exercise terminology, this max effort is known as high intensity.

And when intensity is high, your workouts should be shorter in terms of the total number of sets. Because if you try to combine high intensity and high volume training, you will burn out your nervous system. This is called overtraining.

4. Stick To The Fundamentals

Last but not least is exercise selection. When you’re in a calorie surplus for muscle gain, it’s no time for frills. So ditch the fancy exercises or new-fangled machines for the fundamentals.

Fundamental exercises are like eating the main course before moving on to dessert. They are compound exercises like the squat, deadlift, and bench press. These exercises are key for developing overall strength and size.

Of course, you can include any other exercises that overload the target muscle group. And throw in some auxiliary exercises once you get the fundamentals out of the way.

Key Takeaways

To recap, a calorie surplus is necessary when your goal is building muscle. And your personal calorie surplus depends on your body and your goals.

Here are the key takeaways you should remember:

  • A calorie surplus is when you eat more calories than you burn
  • For maximum muscle gain (bulking) try to eat 15-25% more calories than you burn
  • To minimize fat gain (lean bulk) try to eat 5-15% more calories than you burn
  • Stick with healthy foods and be mindful of your macros and meal times
  • Focus on the fundamental exercises for 5-10 reps per set with longer rest periods and fewer total sets
