Hypertrophy by the Numbers

If you train hard using a non-idiotic plan, you’ll gain muscle and strength. Are some plans better than others? Sure. But as long as you don’t make obvious mistakes, your plan should allow you to build muscle.

Where a lot of people go wrong is their nutrition. Lifters will do one of these two things: fail to eat enough food to support growth, or eat way too much in the hope of forcing even more growth.

If you do the first scenario, you’ll lose some fat but limit muscle growth. If you do the second, you’ll build muscle but add a lot of fat. And the muscle growth likely won’t be much more than what you’d get with a more controlled approach.

Let’s explore exactly how much you should be eating to get the physique you want.

FOOD AND MUSCLE
Building muscle requires protein and energy. Specifically, to build one pound of muscle you need to turn 220 grams of protein into muscle tissue. But that doesn’t mean you only have to eat 220 grams of protein to build one pound of muscle. See, out of the protein you ingest, only around 10% is used to build muscle (1), so it would be closer to 2200 grams of protein.

The process of building muscle requires a lot of energy (2500 to 3500 calories to fuel the growth of one pound of muscle) as well as hormonal/enzymatic support to increase anabolism.

The higher your natural anabolism (testosterone levels, IGF-1 levels, insulin and insulin muscle sensitivity, mTOR activation level) and the lower your natural catabolism (mostly cortisol levels), the better and more efficient your body is at using nutrients to build muscle. That means you require less of a surplus to be able to reach that optimal muscle growth rate. This is why steroid-using bodybuilders can build muscle in a caloric deficit: their anabolism is super high.

Those with a lower natural anabolism will need to eat a larger surplus, mostly from carbs, to reach maximal muscle growth. It’s not because they need more nutrients, but because a large surplus increases several factors involved in increased anabolism and decreased catabolism.
Processing the data, please give it a few seconds...

The most obvious are:
  • mTOR: It’s an enzyme that plays a key role in stimulating protein synthesis, the cornerstone of muscle-building.
  • IGF-1: It’s one of the most anabolic hormones.
  • Insulin: It’s wrongfully seen as the enemy of body composition because people assume it makes them fat. It’s actually anabolic and anti-catabolic for muscle tissue.
In addition to raising insulin, carbs also help decrease cortisol. Basically, consuming carbs makes it easier to build muscle.

CALORIC SURPLUS AND BULKING
Consuming a caloric surplus helps with muscle growth. Does that mean more is better? Not always.

First, let’s establish what the purpose of the caloric surplus is. The main purpose is not, as most people assume, to give you more fuel for the muscle-building process, although it does play a role there.

The primary purpose of consuming a lot more food (mostly carbs) is to increase the hormones and enzymes that maximize muscle growth. The energy aspect can be fueled by your stored energy, although that’s less efficient.

Think about it. Some people can build muscle while in a caloric deficit if protein is sufficient. Why? They have enough stored energy to fuel the muscle-growth process. If they have a naturally high level of anabolic hormones, they’ll be able to build some muscle while in a deficit, even if they get less “anabolic enhancement” from their food.

However, most won’t be able to build a significant amount of muscle while in a deficit, not due to lack of fuel but because of a less favorable anabolic profile.

The problem is, in the hope of building more muscle, some people go “all-out” with the bulking. They resort to a huge caloric surplus and poor food choices. Sometimes it can give the illusion of more size (mostly from fat and water), but it invariably leaves you with a lot of added body fat.

If you’re willing to accept that fat gain because you know you can diet it off, fine. But for many, it just pushes their goal of a muscular and lean physique further away.

Also, if you’re natural, there’s a limit to how much you can increase your body’s anabolism. And at some point, the added food will not contribute to more muscle, at least not directly. It can provide a benefit by allowing you to lift more weight, which can help trigger more growth.

With that said, let’s look at the four basic nutritional strategies to build muscle.

THE FOUR NUTRITIONAL STRATEGIES FOR GROWTH
There are three main approaches when it comes to nutrition to build muscle. Here they are.

1. ALL-OUT BULKING
This refers to ingesting a large surplus (750 calories or more per day) to make sure your body is flooded with nutrients and that all the anabolic factors are maximized.

One benefit? The increased water retention and fat will give you better leverages and makes you stronger. The downside? It comes with more fat gain. Typically, it’s a 2:1 to 3:1 fat-to-muscle gain ratio. That’s why it should be done only if you know you can diet the fat off. It can also be unhealthier because of the weight swing and the fact that a lot of time, it’s just an excuse to eat bad foods.

A FEW QUICK POINTS
  • Make sure you can diet the extra fat off.
  • Don’t bulk if you’re already pretty fat.
  • Make sure that your health markers are good.
  • It’s best for “skinny beginners” or those who have problems adding muscle – they have lower natural anabolic hormones.
  • It’s less useful for easy-gainers – those with naturally high anabolic hormonal levels.
  • It can be advantageous for those who are more interested in strength and size than a leaner physique.
2. CONTROLLED BULKING
With this approach, you consume roughly a 300-700 calorie surplus per day.

This is still enough to make sure your body has all the nutrients it needs to build muscle and keep the anabolic factors high. It comes with less water retention and fat gain than all-out bulking. Typically, a fat-to-muscle gain ratio ranging from 1:1 up to 2:1 is acceptable.

A FEW QUICK POINTS
  • It’s the most sensible approach for most people wanting to build muscle.
  • Most will need to keep a nutritional journal because a 500-calorie surplus can easily become a 1000-calorie surplus if you don’t measure your food.
  • You also need to be able to diet the fat off, even if you’re not gaining as much as you would during an all-out bulking phase.
3. MAINGAINING
This is a term coined by bodybuilder Greg Doucette. It refers to eating from maintenance up to a 200-calorie surplus per day to basically gain muscle while not adding any fat, or very little.

If someone is using steroids or has naturally high anabolic factors, they can likely gain almost as much muscle as they can with controlled bulking. Most, however, will gain anywhere from half to two-thirds of the muscle they could while bulking, but they won’t have to diet off the fat gained.

A FEW QUICK POINTS
  • It works really well for those who are naturally gifted when it comes to building muscle, or those using steroids.
  • It’s the recommended approach for advanced lifters who are near their muscle mass limit or won’t be able to gain a lot more muscle. There’s no logic in trying to force your body to add muscle; it will just add more fat.
  • It’s a healthier approach since there are no huge weight changes.
  • You won’t have dramatic changes in your looks, which is important for a lot of people.
  • Those who have a hard time building muscle will gain nothing (or almost) with this approach.
4. RECOMPING
This refers to building muscle while losing fat. While it’s technically possible, it mostly fails. Most people who try to do it end up not gaining any muscle.

A FEW QUICK POINTS
  • The only people who build muscle with this approach are: those naturally gifted to build muscle, beginners, those coming back from a layoff, and steroid users. Beginners can be those who’ve been going to the gym but never really trained hard, or didn’t go regularly. It’s not just those who’ve never touched a weight.
  • Think of this approach more as a way to lose fat while maintaining muscle mass. Any muscle gain you get is a bonus.
  • You CAN build muscle this way but will be so slow that it appears like you’re not gaining anything. You might be able to gain one or two pounds of muscle in a year.
WHAT SHOULD YOUR PROTEIN INTAKE BE?
This is complex, even though some people mention a simple answer (normally 1 gram per pound, or 0.45 grams per kilo of bodyweight). But it actually depends on many things:
  • Lean mass vs. fat mass: A 330-pound guy with 40% body fat doesn’t need 330 grams of protein.
  • Caloric intake versus daily energy expenditure: You need more protein when in a deficit than when in a big surplus because more protein will be used for energy.
  • Carb intake: Carbs are “protein-sparing,” so the more carbs you ingest, the less protein you need.
  • Stress levels and other lifestyle factors.
Furthermore, very little of the protein you ingest is actually used to build muscle. I mentioned earlier that you need 200-220 grams of protein to build one pound of muscle tissue. But that doesn’t mean you simply need to ingest that amount to have enough to gain a pound of muscle.

Only 10-12% of the ingested protein is used to build muscle. And that’s with powdered protein, which has better bioavailability than food.

So right off the bat, you’d need more like 2000 grams of protein to build one pound (0.45kg) of muscle. Of course, you can’t just shovel protein down your throat, consuming 500 grams per day so that you can build 2 pounds (1kg) per week.

The body has a limited capacity to use protein from a meal and also a limited capacity to build muscle from protein.

So let’s look at the research on protein per meal and per day:

PROTEIN PER MEAL
Dr. Schoenfeld concluded that the ideal protein intake per meal was 0.4 grams per kg of fat-free body mass or .88 grams per pound (2). Consuming more simply leads to increased oxidation of the protein, not more muscle protein synthesis.

PROTEIN PER DAY
The optimal protein intake is between 0.9 to 1.35 grams per pound (2 and 3 grams per kg) of fat-free mass (total weight minus body fat weight). You’d go by the lower end if you’re in a caloric surplus with plenty of carbs, and closer to the upper limit if you’re in a deficit or consuming fewer carbs.

WHERE SHOULD THE REST OF THE CALORIES COME FROM?
Remember, carbs have an advantage over fat. As such, most people should maximize carbohydrate intake when trying to build muscle.

You’ll also need to consume enough fat (especially “good fats”) to have the material to produce hormones and keep the nervous system healthy. It’s likely around 40-60 grams of fat per day, less if you’re using a high-quality omega-3 supplement like Flameout®.

But remember, carbs should be the most abundant, not fats.

MAKING ADJUSTMENTS
The amount of muscle you can build depends on your level of experience and how much muscle you’ve already gained. The more muscle you’ve already built, the slower future muscle growth will be.

A beginner, or someone who hasn’t built a lot of muscle yet, can build around 1.0 to 1.5 percent (0.5 to 0.75 percent for women) of their body weight in muscle per month.

For example, a 170-pound man can build around 1.7 to 2.25 pounds per month. Of course, if you carry a lot of fat, you should lower that number. If you’re a 300-pound beginner with 40-percent body fat, you won’t be gaining 4 pounds of muscle per month.

An intermediate, or someone who’s built something like 15-20 pounds of muscle (7 to 10 pounds for women), can add around 0.5 to 1.0 percent (0.25 to 0.5 percent for women) of their body weight of muscle per month. For example, a 190-pound intermediate will be able to add between 0.95 and 1.9 pounds of muscle in a month.

If you’re advanced or have already gained 20-30 pounds of muscle, your capacity to build muscle comes down to 0.25 to 0.5 percent (0.125 to 0.25 percent for women) of your body weight of muscle per month. A 205-pound advanced lifter would therefore be able to gain 0.5 to 1 pound of muscle per month.

If you’ve gained 40 pounds of muscle or more already, gains will come even more slowly.

For simplicity’s sake, use these numbers to evaluate how much muscle you should be gaining per month:
  • Beginner: 2 pounds per month for men and 1 pound per month for women
  • Intermediate: 1.25 pounds per month for men and 0.7 pounds per month for women
  • Advanced: 0.75 pounds per month for men and 0.4 pounds per month for women
If we consider the fat-to-muscle gain ratio of each of our four strategies, here’s how much weight you should be looking to gain per month:

ALL-OUT BULKING
  • Beginner: 6-7 pounds per month for men and 4-5 pounds per month for women
  • Intermediate: 4-5 pounds per month for men and 3-4 pounds per month for women
  • Advanced: 3-4 pounds per month for men and 3 pounds per month for women
CONTROLLED BULKING
  • Beginner: 4-5 pounds per month for men and 2-3 pounds per month for women
  • Intermediate: 3-4 pounds per month for men and 1.5-2 pounds per month for women
  • Advanced: 2-3 pounds per month for men and 1.5 pounds per month for women
MAINGAINING
  • Beginner: 2-3 pounds per month for men and 1-1.5 pounds per month for women
  • Intermediate: 1.25 to 2 pounds per month for men and 0.7 to 1 pound per month for women
  • Advanced: 0.75 to 1.25 pounds per month for men and 0.4 to 0.7 pounds per month for women
RECOMPING
  • Beginner: 1-2 pounds per month for men and 0.5 to 1 pound per month for women
  • Intermediate: 0.75 to 1 pound per month for men and 0.25 to 0.5 pounds per month for women
  • Advanced: 0.5 to 0.75 pounds per month for men and 0.25 pounds per month for women
If you’re gaining weight FASTER than you should be, based on your level and nutritional strategy, you’ll need to lower calories accordingly (via carbs and/or fats).

If you’re gaining weight SLOWER than you should be, you’ll need to increase calories (mostly in the form of carbs and/or protein).

FINAL NOTE
Most of the time, if you fail to gain muscle – especially if you’re passionate about training – the issue is nutrition, not training. Figuring out how much to eat is essential to the achievement of your physique goals. Don’t leave it to chance.

Excellent information. I really respect Schoenfield’s work.
 
Your muscle growth doesn't just depend on the amount of food you eat. It depends on several factors. It's up to each individual to choose how to gain muscle mass. For example, I take special supplements for muscle growth. For a year I tried to achieve muscle growth, and I did everything to achieve it. I switched to a proper diet and ate as much as I needed to. I spent a lot of time at the gym and saw my body change. But it wasn't the change I wanted. But when I started taking supplements, I began to notice changes in my body that I really liked. I realized that my muscles began to grow. Now I really like the way my body looks. Good luck to you)
 
When I wanted to become a bodybuilder, I immediately remembered Dr. Burt's seminars. He is a doctor who left medicine and began to conduct seminars and blogs. Blogger doctor, that sounds cool. Here he was prescribing me a diet plan on medicalweightlosslehighvalley.com to lose weight. I think a lot of people will want to read his creations. He also has a book and free lectures that you can study from. During sleep, the body completely shuts down, which has a beneficial effect on certain metabolic processes. Some people claim that 3-4 hours of sleep is enough for normal functioning, but most people need at least 7-8 hours. That's what sleep helps me recover. That's cool.
