The Top 5 Best Weight Gainer and Protein Supplements for Muscle Growth

What are the top five best weight gainers and protein supplements for muscle growth and workout support? Find out what it takes to build new muscle and bulk up as you work out.

In order to bulk up and build muscle you must be taking in optimum nutrition. Muscle mass cannot be created without the building blocks of protein (amino acids) and enough fuel for the energy that muscle creation requires. So if you’re on a journey to muscle building, make sure you take the best weight gainer and protein supplements along. What are they, you ask? We have the answers, backed by scientific research.

How to Build Muscle: The Basics

The formula for muscle growth is pretty simple: you gain muscle when the rate of muscle protein synthesis exceeds the rate of muscle protein breakdown.

To activate this formula, you must push your workout to demand new muscle creation, and then supply your body with enough muscle-building nutrients to meet that demand. That means extra energy and protein support before and after your workout, plus enough fuel to minimize muscle breakdown (catabolism) while you sleep.

If your body is lacking in any of the main ingredients needed for lean muscle creation, it will start harvesting other muscle cells for those supplies. It’s like tearing the plumbing out of your house to outfit a guest house: it doesn’t make sense, but what the body needs, it takes, regardless of logic.

But never fear. You don’t have to worry about stealing nutrients from your precious muscles as long as you have the right nutrient intake. Let’s find out the the best weight gainer and protein supplements for you.

The Top 5 Best Weight Gainer Supplements for Muscle Growth

The Top 5 Best Weight Gainer Supplements for Muscle Growth

While many people think they work out to lose weight, it would be more correct to say they’re working out to lose body fat. Muscle is denser than fat, so for those looking to become lean and strong and for those looking to bulk, the goal is actually to gain weight in the form of muscle mass, and there are high-quality protein and mass gainer supplements to help.

1. Milk Protein Supplements

It seems almost too obvious to mention, but you need protein to build muscle bulk. Muscle is made of protein, and study after study shows that protein supplements help exercising adults gain more muscle than those who don’t consume extra protein. These protein supplements specifically include whey protein (derived from the liquid part of milk) and casein supplements for exogenous amino acid support during wake and sleep.

When to take protein supplements, pre- or post-workout (or both), depends on the type of workout you’re doing. How much depends on your body composition and your bulking goals. As a macronutrient, protein should be between 10% and 35% of your daily calorie intake, and researchers suggest between 0.6 and 0.9 grams of protein per pound of body weight each day to support muscle growth (calculate your own serving size).

Along with whole food proteins, protein powder supplements like casein (derived from the solids of milk that make up cheese) and whey protein powder can help put your muscle gain over the top. Whey is fast-digesting and casein slow, so taking them together covers all the bases.

2. Creatine

Eating a high-protein diet is one thing, but for real gains in lean muscle mass and overall bulk weight, high-quality protein supplements maximize your muscle-building profits. Creatine is a protein supplement derived from the amino acids glycine, arginine, and methionine. It’s consumed naturally from animal meat and seafood and is one of the most popular supplements for muscle growth and bodybuilding.

Creatine has been widely studied and has proven results in increasing muscle mass, improving rapid energy production (important for workout endurance), and consistently enhancing performance and muscle gain.

Creatine monohydrate supplements have been shown over and over again to be safe and effective at anywhere between 20 grams per day as a loading dose (split into 4 servings) and 3-5 grams for indefinite maintenance of muscle mass.

3. Weight Gainers

What separates weight gainers from protein supplements isn’t a lack of protein—weight gainers are high in both protein and carbs—it’s that they’re specifically designed to be high-calorie supplements for those who have a hard time gaining weight no matter how much they eat. Weight gainers are essentially protein supplements plus concentrated carbohydrates and fats for extra energy and bulk.

Some of the most popular products include:

  • MuscleTech Mass Tech: With 840 calories per serving and 63 grams of protein from whey, casein, and creatine monohydrate, this product also adds the branched-chain amino acids (BCAAs) for extra workout support. Flavors come in Chocolate, Vanilla, and Birthday Cake.
  • BSN True Mass 1200: The best mass gainers are those with a higher calorie count per serving, and this product delivers 1,200 calories per 310-gram serving. With 50 grams of protein, 213 grams of carbs, and 17 grams of fat, BSN True Mass 1200 flavors include Chocolate Milkshake, Strawberry Milkshake, and Cookies & Cream.
  • Optimum Nutrition Serious Mass: Even higher in calories with 1,250 per serving, this product has 50 grams of protein, 252 grams of carbs, and 4.5 grams of fat in flavors like Banana, Chocolate, and Chocolate Peanut Butter.
  • MusclePharm Combat XLThe calorie content is 1,270 per serving, with 50 grams of protein and 7 grams of fat, in Chocolate Peanut Putter, Chocolate Milk, and Vanilla flavors.
  • Dymatize Super Mass GainerHigher still in calories at 1,280 per serving, this mass gainer has 52 grams of protein from whey, casein, and eggs, plus 246 grams of carbs and 9 grams of fat.

Easily ordered online via Amazon or directly from the manufacturers, these types of pro gainers provide a sort of universal nutrition profile, with protein for lean mass creation, complex carbohydrates for energy and bulk, and fats like MCTs (medium-chain triglycerides) for healthy weight gain.

With so many options available, you can find products with animal proteins from grass-fed, cage-free sources, maltodextrin from non-GMO organic tapioca, and even gluten-free options with no artificial sweeteners for your weight gainer shakes.

4. Exercise Boosters

There’s almost no way to gain muscle without exercise, so optimizing your workout energy and performance is important. Here are a few supplements to boost your workout.

5. Essential Amino Acids

Speaking of amino acids, as we mentioned at the top of this article, there is no new muscle creation without amino acids, specifically the full host of all nine essential amino acids. While many protein supplements focus on the branched-chain aminos, BCAAs are only three out of the nine essential aminos, and if any one of the essentials is deficient, the body starts catabolizing other muscle molecules to get it.

While studies show that BCAAs are indeed critical for new muscle growth, so are the other six essential amino acids, and other studies have found that supplementing with the BCAAs on their own doesn’t show any preferential effects towards muscle building. You need a balanced EAA supplement to truly benefit new muscle growth and bulk.

Gain Muscle, Gain Weight

Alongside whole food protein sources, supplements designed for weight gain, workout support, and new muscle creation can go a long way towards setting you up for success as you work to bulk up. We here at AminoCo are proud to offer a product with all the essential muscle-building amino acids, along with other nutrients for muscle growth, liver health, detox support, and more, all to provide the fitness-minded with the best of everything.

How to Use Amino Acids for Bodybuilding

Amino acids have become some of the most popular types of bodybuilding supplements across multiple disciplines. Both BCAAs and EAAs can be used on their own or in the form of “stacks”—specialized blends of multiple supplements that work together synergistically to provide even greater benefits than when taken on their own.

Bodybuilding usually refers to increasing and sculpting muscle mass for appearance as well as strength. In a more general sense, bodybuilding can refer to increasing muscle mass and function for the purpose of competing in sports such as football or power sports (e.qg., shot putting, discus throwing, etc.). It is a given that bodybuilding requires resistance training. If bodybuilding is for the purpose of improving competitive performance in a specific sport there are likely to be training requirements unique to that sport. This discussion on amino acids for bodybuilding will, therefore, not focus on the specific aspects of training. Regardless of the goal of training, amino acids play a key role in bodybuilding.

The Impact of Nutrition on Bodybuilding

Training tends to be the first factor most consider when seeking to build lean muscle, however, the nutrients we provide our bodies with can be equally influential—or more so—in determining how quickly we progress toward our goals. No matter how intensely you train, you will not be able to achieve the results you desire if you’re lacking certain crucial nutritional elements.

Obtaining all the nutrients you need from your diet alone in the quantities necessary for maximal bodybuilding results can be challenging. That’s where workout supplements come in.

By taking targeted sports nutrition supplements, you can ensure you get all the nutrients you need to build muscle, speed recovery time, decrease muscle soreness, amp up energy levels, and more.

Bodybuilding Supplements Then and Now

Depending on how broadly you interpret the idea of dietary supplementation, the idea of bodybuilding supplements can be traced back to ancient Greece.

According to Professor Andrew Dalby and other experts, Greek and Roman athletes consumed large quantities of meat and wine as well as herbal concoctions and tonics with the goal of increasing their strength and stamina.

In the early 1900s, Eugen Sandow, a pioneering German bodybuilder whose legacy earned him the honorific “father of modern bodybuilding,” advised all who wished to maximize their muscle growth to adhere to the dietary rules he himself followed. Bodybuilder Earle Liederman, who rose to prominence in the 1920s, recommended drinking what he called “beef juice” or “beef extract” (a substance the luminaries of today’s wellness landscape call “bone broth” and chefs simply refer to as “consommé) in order to speed muscle recovery.

In the 1950s, protein powders entered the picture as recreational and competitive bodybuilding became ever more popular with ever-broader audiences in the United States and elsewhere. Irvin P. Johnson, who operated a bodybuilding gym in Chicago, was one of the first to market egg-based protein powder. According to an article he published in Iron Man with the title “Build Bigger Biceps Faster with Food Supplements,” his specialized line of protein powders fueled serious strength gains. According to the article, he went from only being able to leg press 165 pounds for 10 repetitions to 660 pounds for 12 repetitions!

The bodybuilding supplement industry grew at an exponential rate throughout the 1970s and 1980s, fueled both by increased interest in recreational bodybuilding as well as advancements in advertising. Then, in October of 1994, Congress passed the Dietary Supplement Health and Education Act, a piece of legislation that transferred responsibility for determining the safety of dietary supplements such as protein powders and other mainstays of sports nutrition from the government to the manufacturers of the products. Unless they added a new dietary ingredient, manufacturers were no longer required to provide the U.S. Food and Drug Administration (FDA) with evidence to substantiate the safety or efficacy of their products. Legal experts believe this opened the door for the supplement industry to sell even more of their products. According to a Consumer Reports publication, annual sales of sports nutrition supplements hit $2.7 billion in 2010. And according to the “Sports Nutrition and High Energy Supplements – Global Market Outlook (2017-2026)” report sports nutrition and high energy supplements made $44.58 billion in 2017 with an outlook of $124.85 billion by 2026.

Defining the Term “Bodybuilding Supplements”

Just as the term bodybuilding can encompass both physique-focused and performance-focused endeavors, so too can the term “bodybuilding supplements” encompass a multitude of dietary supplements utilized by individuals engaged in bodybuilding as well as weight lifting, mixed martial arts, and other athletic pursuits to increase lean body mass as well as bring about other desirable outcomes such as:

  • Decreased body fat
  • Sharper muscle definition
  • Enhanced athletic performance

Amino acids have become some of the most popular types of bodybuilding supplements across multiple disciplines. Both branched-chain amino acid supplements (BCAA supplements) and essential amino acids (EAAs) can be used on their own or in the form of “stacks”—specialized blends of multiple supplements that work together synergistically to provide even greater benefits than when taken on their own.

Making the Most of the Building Blocks of Protein

Amino acids have earned the nickname “the building blocks protein” because of the vital role they play in creating muscle tissue. While it’s certainly possible to obtain all the amino acids you need simply by eating high-protein foods like eggs, lean meats, legumes, vegetables, and pseudo-grains like quinoa, amino acid supplements can be a convenient and efficient way to maximize the benefits of amino acids.

One of the most compelling reasons to use supplements can be captured in a single word: bioavailability. Bioavailability refers to how efficiently a substance can be metabolized and the percentage of what’s ingested that’s utilized for its intended purpose inside the body.

Several factors determine the bioavailability of each amino acid. For example, when taking in amino acids from a food source, the amount of fat contained in that food influences the length of time it takes for amino acids to be put to use. The way you cook food can also impact the amino acids it contains. Some heat-sensitive amino acids can even decompose when cooked. And not all amino acid supplements are metabolized at the same rate. The physical nature of the supplement will have the most significant influence on its bioavailability. A BCAA powder, for instance, will be digested differently than a supplement in pill or liquid form. The extent to which a supplement is pre-digested as well as whether it contains any fillers or binders impact its overall bioavailability.

Understanding Muscle Protein Turnover

Muscle protein turnover is the metabolic basis that powers increased muscle mass, strength, and function.

Muscle protein turnover refers to the constant breakdown of older muscle proteins that are no longer operating at peak efficiency and their replacement with newly synthesized, more efficient muscle protein fibers. The balance between protein synthesis and breakdown determines whether a muscle is growing or shrinking.

Muscle function is accomplished by the contraction of muscle protein fibers. Muscle strength and function are determined by how many muscle protein fibers you have and the efficiency with which they contract. Increasing muscle protein mass and contractile efficiency is accomplished by optimizing muscle protein turnover.

For bodybuilding, the goal is to make the rate of muscle protein synthesis exceed the rate of protein breakdown. Further, the increased balance between muscle protein synthesis and breakdown should optimally be accomplished mainly by stimulating synthesis, not lessening breakdown—protein breakdown gets rid of muscle proteins that are not functioning efficiently, so it is good to keep that process functioning at full speed.

The Mechanics of Muscle Protein Synthesis

Muscle proteins are composed of a series of amino acids hooked together in a specific order determined by the messenger RNA (mRNA) in the cell for each specific muscle protein. The sequence of the mRNA is dictated by the DNA in the cell. There is a specific molecule for each amino acid (tRNA) that delivers it to the mRNA as required for incorporation into the protein that is being produced.

A simple, conceptual way to think about the process of muscle protein synthesis is to compare it to the construction of a building. The DNA is basically the idea for the design of the building. The RNA is the written plan or blueprint, and transcription of the mRNA from the DNA is the process of writing up the plan. The tRNA molecules that bring the amino acids to the mRNA for incorporation into protein are like trucks that bring bricks to the building site, and the hooking of amino acids together in the proper order on the mRNA corresponds to the builder putting the bricks together according to the blueprint. The protein is the final product, or completed building, ready to serve its function.

The details of how muscle protein is made are important only so that it is clear why all the amino acids must be available in abundance. If the mRNA dictates that the next amino acid in the chain making up the protein is a particular amino acid that is deficient, then the process is halted and no muscle protein is produced.

How Amino Acids Impact Muscle Protein Synthesis

We must derive certain amino acids, as I touched on earlier, from dietary protein. However, the human body can synthesize other amino acids through chemical reactions that occur in the liver and select sites throughout the body.

The amino acids that must be obtained from the diet are called essential amino acids, or EAAs, while the amino acids that can be made in the body are called nonessential amino acids, or NEAAS.

The nine essential amino acids are leucine, isoleucine, valine, phenylalanine, lysine, methionine, phenylalanine, threonine, and tryptophan. Three of the EAAs, leucine, isoleucine, and valine, have been subcategorized as branched-chain amino acids (BCAAs), a descriptor which refers to their chemical structure. We typically put the number of nonessential amino acids at 11, as that’s how many NEAAs can be found in human protein, though other NEAAs like citrulline and ornithine can be found elsewhere in the body.

Since your body can produce NEAAS and they are available in abundance, the availability of EAAs serves as the limiting factor for setting the rate of muscle protein synthesis.

Using Essential Amino Acids to Stimulate Muscle Growth

Consuming essential amino acids, either as dietary protein or supplements, is the most potent stimulus of muscle protein synthesis. Consuming nonessential amino acids, either alone or with EAAs, has no impact.

EAA supplements have been shown to trigger muscle protein synthesis and increase muscle mass, strength, and physical function in at least 25 clinical trials. The muscle-building response to EAAs is 2 to 4 times greater than the muscle-building response to the same amount of a whey protein supplement. The muscle-building response to EAAs is even greater than the response to hormonal treatment with testosterone, growth hormone, or insulin.

There is one very big must when it comes to EAA supplementation, however. In order to be effective, all the EAAs are required. That being said, there are varying degrees of importance among the EAAs.

Leucine, which is both an EAA and a BCAA, is particularly important. Leucine is the most abundant EAA in muscle protein, so it should comprise the highest proportion of an EAA supplement. Beyond its role as a component of muscle protein, leucine can signal the molecular mechanisms within the cell to initiate the process of protein synthesis. Important as leucine may be, however, it cannot function alone. All the other EAAs are required as well, roughly in proportion to their relative content in muscle. It is not possible to make muscle protein from leucine alone.

The Role of Essential Amino Acids for Bodybuilding

It is clear from the above discussion that making sure you consume enough essential amino acids is an important part of bodybuilding. Even when using EAA supplements, the main source for your essential amino acids intake will likely be dietary protein. Therefore, the place to start is with your diet.

Protein is the key dietary component of the basic bodybuilding diet. It will increase your muscle mass. You should set a goal of eating approximately 30% of your caloric intake as high-quality protein.

When I say high-quality protein, I mean a protein that contains a high abundance of essential amino acids. High-quality proteins are generally animal-based proteins. These protein food sources also have a significant amount of non-protein calories. Therefore, eating a sufficient amount of high-quality protein to supply all the EAAs you need is difficult through normal diet alone.

You will most likely run into issues with the flexibility of your diet when eating this amount of high-quality protein food sources because of the non-protein calories. Therefore, EAA supplements can play a vital role in helping you meet your dietary goal for EAA intake.

While the focus of your basic diet should be high-quality protein, you must remember that energy substrates (carbohydrates and fat) are important too. As an example, in a tightly controlled study, subjects drank the same amount of protein in the form of milk. In one case, it was skim milk, and in the other case whole milk. The stimulation of muscle protein synthesis was greater with the whole milk. Under these study conditions, the additional calories provided by the fat in the whole milk helped to fuel muscle building.

You must be in a positive energy balance to gain a significant amount of muscle mass. Carbohydrate is of less importance for resistance training than it is for endurance training, but you should eat enough fruit and vegetables to meet the RDAs for micronutrients. Also, carbohydrate intake will stimulate insulin release, and insulin is an anabolic hormone that will increase the amount of muscle protein made from your EAA intake.

Fat intake will also amplify the anabolic effect of EAAs, and therefore you can eat animal-based, high-quality protein foods without worrying about eating too much fat.

What you do want to keep in mind with your bodybuilding diet is that the more you eat, the bigger you will get. If you do eat a lot while lifting heavy weights and consuming EAA supplements as recommended, a significant part of the weight gain will be muscle.

You will also gain fat with this dietary approach, so you need to carefully monitor your body composition to be sure that the extra fat you put on does not counteract the benefits of the muscle gain. In a sport like powerlifting, that is not likely to be the case, but if you are bodybuilding for appearance, you must reach a balance between muscle and fat gains. This can be accomplished by incorporating aerobic exercise into your training program.

How to Use Essential Amino Acids for Optimal Bodybuilding Results

amino acids for bodybuilding

The research documenting the optimal use of amino acids for bodybuilding is extensive. Experts can provide precise guidance on the effects of taking EAAs both pre-workout and post-workout.

Consuming 15 grams of EAAs 30 minutes before starting your workout will elevate blood concentrations of essential amino acids throughout your workout and stop the muscle breakdown that would otherwise occur. A 15-gram dose of EAAs achieves a greater response on muscle protein synthesis than either casein or whey protein can, without creating the fullness that can hinder a workout.

Then immediately after your workout, take another 15 grams of EAAs. One hour later, take another 15-gram dose.

These recommendations stem from the assumption that you will be working out every day. When you do take off days, you should still consume the same amount of EAAs. Instead of using your workouts to determine the timing, however, take your EAAs between meals.

Between the completion of dinner and breakfast the next morning, you may go for 12 hours or more without food. During this post-absorptive time, muscle tissue breakdown transpires in order to supply amino acids to tissues and organs that have no protein reserve. Therefore, to fuel maximal muscle-building response around the clock, you should consume another 15 grams of EAAs before bedtime. If you have wholly committed to maximizing muscle gain, you can even set your alarm for a final dose at about 4 am.

Alternatively, you can take 20 grams of casein protein at bedtime. Because casein coagulates in the stomach, your body digests it at a slower rate, meaning the amino acids it contains are then absorbed over many hours. While the anabolic effect will be less than if you take the EAAs, this approach will save you the trouble of getting up in the middle of the night.

The total amount of supplemental EAAs you ingest should be in the range of 60 grams per day. Consuming this amount of EAAs will stimulate the production of new muscle protein without you having to also take in a significant amount of non-protein calories. The result will be a lean body with increased muscle mass and minimal increase in fat mass. Sixty grams of EAAs in addition to what you eat as part of your bodybuilding diet is needed to drive protein synthesis past what may be your normal genetic limit.

Do EAA Supplements Have Side Effects?

This a reasonable question, because bodybuilding requires a much higher than average EAA intake. An important caveat to state up front is that I am focusing exclusively on side effects from EAA supplements.

When your EAAs come from an unusually high amount of dietary protein intake, that will increase the rate of amino acid oxidation and as a result, burden the kidneys to excrete the ammonia and urea that are natural byproducts of NEAA oxidation.

The great thing about EAA supplements, however, is that there is no such increased oxidation of NEAAs when EAAs are consumed. This is because NEAAs are not also being consumed but are rather being produced in the body. In fact, the oxidation of the NEAAs actually goes down, since they are being incorporated into protein at an increased rate.

Consequently, there is no reason to worry about the side effects of EAA supplements. The FDA has determined EAA supplements to be Generally Regarded as Safe (GRAS), while the Food and Nutrition Board of the National Academy of Science has determined that there is no upper limit of consumption beyond which would not be safe.

Amino Acids and Gaining “Good” Weight After Serious Illness, Surgery or Injury

Recovery almost inevitably involves regaining the weight that was lost. It is important that the regained weight is largely muscle, and that you don’t replace the muscle you lost with new fat. The key to gaining good weight is optimal amino acid nutrition.

Obesity has become such a pervasive problem in the United States that few people think about gaining weight on purpose. That is, until they lose a drastic amount of weight due to serious illness, surgery, or injury. The weight lost in these circumstances includes a significant amount of muscle. Recovery almost inevitably involves regaining the weight that was lost. It is important that the regained weight is largely muscle, and that you don’t replace the muscle you lost with new fat. The key to gaining good weight is optimal amino acid nutrition.

Why Illness, Surgery, or Injury Often Results in Weight Loss

When you become seriously ill, undergo the physical stress associated with major surgery, or suffer a severe injury, your body may enter what’s known as a catabolic state.

The catabolic state refers to the rapid loss of weight, especially muscle, accompanying physiological stress. Some events that might cause a catabolic state include major surgery or trauma, serious chronic diseases like cancer and heart failure, or acute illnesses such as pneumonia. Even a serious case of the flu can create a catabolic state. There are two components of the catabolic state:

  1. Changes in muscle metabolism that are part of the stress response
  2. Decreased appetite

Many catabolic states involve hospitalization during the most severe stage, perhaps even in the intensive care unit. Receiving an adequate intake of nutrients in a severe catabolic state becomes challenging for several reasons. First, the normal anabolic (muscle building) response to protein intake diminishes, a condition called anabolic resistance. Second, glucose metabolism is altered significantly—insulin resistance kicks in and fat accumulates in the liver. And third, fatty acid levels in the blood drastically increase. During the acutely severe stage, the debilitative effects of bedrest are often superimposed onto those fundamental elements of the body’s stress response.

The primary nutritional focus for helping individuals weather a catabolic state with the most minimal damage possible should be the consumption of essential amino acids (EAAs). Providing your body with a steady supply of essential amino acids can effectively slow down the loss of muscle that accompanies anabolic resistance. Even EAAs have a limited effectiveness in the catabolic state, however, and some degree of muscle loss is inevitable.

Full Recovery Involves Gaining Good Weight

Once the initial health issue has passed and you’ve entered the recovery phase, you may actually be happy to have lost some weight. The problem with this perspective is that the stress response specifically targets muscle loss. Although some fat is lost as well, a significant portion of weight loss that occurs in a catabolic state comes directly from your muscle mass.

Further, it’s important to make peace with the fact that you will almost inevitably regain the weight that you lost in one way or another. The key is to restore your lost muscle mass, and avoid unfavorably affecting your body composition by regaining the weight you shed as fat.

Making a Healthy Weight-Gain Meal Plan

Making the decision to gain weight should not be interpreted as a license to binge on high-calorie, sugary, salt-laden junk food. While that could very well provide you with the extra calories required to gain weight, you’ll be undermining your overall health in the process.

The point of gaining good weight is to restore your lost muscle mass and subcutaneous fat, not to build up deposits of belly fat that have been linked to adverse health outcomes including type 2 diabetes and heart disease.

The best healthy weight-gain strategy for you will depend on your individual circumstances and goals; however, there are certain strategies for devising a healthy weight-gain meal plan and exercise protocol that can be universally beneficial.

The Importance of Protein

Protein should be the macronutrient that dominates your meal plan for gaining good weight. As you may be aware, your muscles are formed from protein. Making protein the base of your diet, therefore, makes it far more likely that the extra calories you take in will be transformed into muscles, not excess body fat.

Initially, anabolic resistance lingers after recovery, which will limit the efficacy of the protein you consume. As your physical condition improves, your body will become more efficient at putting the dietary protein you consume to work promoting muscle growth.

Research has consistently demonstrated that getting your extra calories from protein results in more lean muscle mass gains and less fat mass gains.

A study published in JAMA compared the effects of low-, normal-, and high-protein diets on weight gain and body composition. All participants ate diets designed to provide approximately 40% more calories than needed to maintain their current weights. The authors found that participants on the high-protein diet gained significantly more lean body mass—in other words, muscle mass—than those on the normal- and low-protein diets.

Aim to consume between 25% and 30% of your daily calories in the form of high-quality protein. Another way to conceptualize the amount of protein needed to gain weight is to shoot for between 0.7 and 1 grams of protein per pound of body weight. Depending on your calorie intake, you may find you have room to increase that.

One thing to keep in mind: protein is highly filling. You may find that increasing the number of grams of protein you eat each day substantially reduces your appetite. That’s why increasing your protein intake is also a helpful strategy for meeting weight-loss goals (albeit, without the overall strategy of eating more than enough calories to meet your body’s energetic needs). While this could make it challenging for you to eat the extra calories needed for weight gain, I’ll provide helpful tips on how to overcome this hurdle later on in the article.

Structuring your diet around protein will involve incorporating a variety of high-quality protein sources, such as:

  • Meat
  • Fish
  • Eggs
  • Many dairy products
  • Legumes
  • Nuts

Unless you have dietary restrictions that rule out animal proteins, I recommend making those the focal point of your healthy weight-gain meal plan. Animal-based proteins, including many dairy products, not only contain all the essential amino acids your body needs to build muscle, but also have a higher ratio of overall calories from protein. On average, about 50% of the calories in animal protein food sources come from protein. In contrast, around 70% or more of the calories in many plant-based protein food sources may come from carbohydrates.

How to Handle Fats and Carbohydrates

Since your primary—and quite likely, unfamiliar—goal is to gain weight, you may need to adjust the way you typically think about food. If you’re accustomed to restricting your carbohydrate or fat intake, this is the moment to let go of that. Placing limits on how much fat or how many carbs you eat will only make it harder for you to eat the calorie-dense foods required for healthy weight gain.

Yet another reason to prioritize animal protein as a mainstay of your meal plan for gaining good weight is that the majority of the non-protein calories in these foods come from fat. While many of us have been conditioned to think eating fat is harmful, that is certainly not the case—especially if you are recovering from a catabolic state. Adding more healthy fats to your diet is a wonderful way to increase your total caloric intake and support your body as it re-builds lost muscle.

If you’re going to worry about eating too much of any of the three macronutrients (and as long as you’re eating healthy, whole foods, there’s little cause for any concern at all), direct your attention to carbohydrate consumption. The metabolism of dietary carbohydrate requires the effective action of insulin, and the catabolic state induces a resistance to the normal action of insulin that may persist for months. Insulin resistance makes carbohydrate metabolism less effective as an energy substrate. In simpler terms, this makes it more likely that the carbohydrates you consume will be converted to fat and stored in the liver.

Because of this potentiality, I find it reasonable to limit carbohydrate consumption to between 20% and 30% of your overall caloric intake. That said, you will likely see the greatest weight-gain results if you include plenty of protein, fat, and carbohydrates at each meal.

Strive to eat at least three macronutrient-optimized meals per day. If you have a good appetite (and the physical activity routine I describe below will help to stimulate that), you should also feel free to add in energy-dense healthy snacks whenever possible.

As you regain your muscle mass and approach complete recovery, your basic diet should evolve towards one of the diet options that suits your individual needs and preferences. Maintaining a high-protein intake (about 25% of your daily calories) will help to maintain the muscle you have regained during recovery.

24 of the Best Foods to Help You Gain Weight in a Healthy Way

Whole, single-ingredient, healthy foods should form the basis of your healthy weight-gain meal plan. However, as I mentioned in reference to high-protein foods, these foods do tend to be more filling than the quick-and-easy processed foods that can be so tempting to rely on. This can make it challenging to create the calorie surplus necessary to gain weight.

To encourage yourself to eat enough of these foods to gain the weight you lost, get creative with your use of spices, sauces, and condiments. Make your meals so irresistibly delicious that you simply have to clean your plate.

Another helpful tip for getting the amount of calories needed to gain weight fast is to emphasize energy-dense foods. These foods contain a high number of calories relative to their weight. Here are seven types of energy-dense foods to add to your grocery list:

  1. High-fat dairy: There are a plethora of good options in this category. Think whole milk, full-fat yogurt, organic cheese, and so on. If you’re vegan, full-fat coconut milk is your best option.
  2. Meat: Let your tastes, and the usual best practices for buying meat, guide you. Choose pasture-raised or free-range options whenever possible. And the fattier the cut, the better.
  3. Nuts: Go nuts for nuts! Avoid overly processed options—you can always add your own flavor enhancers if you like. Almonds, walnuts, and macadamia nuts are particularly nutrient-rich. Nut butters can be a fabulous, calorie-dense treat, but steer clear of varieties with added sugar.
  4. Fats and oils: It’s hard to get more energy-dense than fats and oils! Extra virgin olive oil, coconut oil, and grass-fed butter all have many desirable characteristics. And don’t forget avocados, that beautifully fatty fruit!
  5. Root vegetables: These starchy veggies are the perfect way to add healthy carbohydrates to your plate. Load up on sweet potatoes, yams, rutabaga, turnips, and even plain old potatoes.
  6. Grains: Whole grains can be another solid option when it comes to healthy carbohydrates. Try making oats for breakfast or serving brown rice with your dinner.
  7. Healthy snacks: This is the broadest category, and your personal tastes will, of course, come into play here. Some of my personal favorites include dark chocolate and dried fruit as well as homemade granola and trail mixes.

You may have noticed that few fruits and vegetables appear on the list above. I’m certainly not suggesting that you stop eating fruits and vegetables, however, those foods are unlikely to contribute significantly to the caloric excess you are attempting to create.

Exercising to Rebuild Lost Muscle Mass

Exercise is always important in relation to muscle mass and function, and never more so than when you are recovering from a catabolic state. Exercise is the best way to reverse muscle loss and regain normal function. Prioritizing exercise—and strength training in particular—during your recovery period encourages your body to store the extra calories you eat as muscle, not fat.

However, depending on your particular situation, it may be difficult to follow the general guidelines of the American College of Sports Medicine for the amount and intensity of exercise. It may be necessary to go to a physical therapist initially, followed by an experienced trainer, to formulate the best plan for recovery exercises.

The general guideline of resistance exercise 2 times per week and aerobic exercise 5 times per week is appropriate, with the understanding that the level of intensity can be quite limited at first. Try to increase the weight you lift as well as the number of repetitions and sets you do over time. When it comes to cardio, there’s no need to deprive yourself of the fitness benefits associated with this type of exercise, but be sure to adjust your caloric intake to account for the calories you burn off. Remember, your goal at the moment is to consume an excess of calories.

The key to successful recovery is understanding that your exercise capacity will eventually return if you stick with it. This may be easier said than done in the depleted state after recovery from a catabolic state, but there is no substitute for persistence.

Using Essential Amino Acid Supplements to Maximize Your Recovery

As I explained earlier, essential amino acids play a key role in helping your body recover from catabolic stress. That’s part of the reason why it’s so vital that you increase your protein intake.

You may also find it helpful to add on an essential amino acid supplement specifically formulated to target an increase in muscle mass and function.

Ideally, you will want to take your essential amino acid supplement between meals to avoid the muscle loss that normally occurs in the absence of the absorption of dietary protein. As you regain strength, you will want to start coordinating the timing of your supplement intake with your exercise routine. It is optimal to take essential amino acids about 30 minutes before exercise and then again after exercise. Regardless of how light the exercise is, it is, in fact, activating the muscle to begin the process of restoration to full strength. Essential amino acids should be taken in conjunction with whatever physical activity you perform.

You’ll want to choose an amino acid supplement formulated with essential amino acids in a relatively pure form. That means avoiding blends that include other ingredients that simply add non-protein, non-amino acid calories.

The dosage of essential amino acids that gives the greatest stimulation of muscle protein synthesis is 15 grams—more than 15 grams at one time won’t provide much additional benefit. On a gram-for-gram basis, smaller doses may be more effective. A dose as low as 3.6 grams has been shown to be a potent stimulator of muscle protein synthesis. Therefore, there is quite a bit of flexibility in dosing.

Nonetheless, the larger the dose (up to 15 grams), the greater the muscle gain with each dosage. For optimal restoration of lost muscle, 15 grams twice per day between meals will give you the fastest results.
