What is a weight gainer and how does it help to Gain Weight for skinny guys?

If you don’t know anything about weight gainer supplements – Their advantages and disadvantages, then you must read this section very carefully.

As the name suggests Weight gainer or Mass gainer – Is a supplement in powder form, usually consumed in the form of a shake that helps to gain weight and muscles fast.

Weight gainers help you to gain weight fast – Because they are high in calories and help you to be in a caloric surplus, which is very important to gain weight and muscles.

A weight gainer or mass gainer can easily replace a meal because they contain a good amount of calories [Especially carbohydrates and protein].

Combined with a good diet and weight training, weight gainers can help you to gain weight and muscles fast.


Benefits of weight gainer

Here are some important factors that why you should include the best weight gainer supplements in your diet, being a skinny guy.

benefits-of-weight-gainer-for-skinny-guys

Helps you to Gain weight and muscles fast

Weight gainers are very high in calories, carbs, and protein that helps you to be in a caloric surplus, which is very crucial for weight and muscle gains.

Caloric surplus means eating more calories from your daily maintenance calories to gain weight and muscles.

When you are not getting enough calories from your meals, then adding a weight gainer supplement to your diet can help you to meet your daily caloric needs.

Helps to fulfill your daily caloric needs

As we all know that to gain weight and muscles we need to eat extra calories from our daily maintenance calories.

When you do workouts or simply a day job that requires a lot of physical activities, you burn a lot of calories that time.

Therefore you need to consume a lot of calories to keep up with your lifestyle and maintain your body.

In this case, adding a weight gainer supplement to your diet can easily help you to fulfill your daily caloric needs.

For example, suppose if you need 3500 calories a day, then adding a weight gainer supplement to your diet can easily help you to fulfill your daily caloric needs.

Therefore, adding the best weight gainer supplement is very important for skinny guys.

Helps to replenish the glycogen store

Glycogen is stored energy in the body that is used by the muscles during the workout or in many other physical activities.

This means that when doing any workouts, especially in weight training, your muscles need glycogen to perform those high-intensity exercises.

Carbs are broken down in our body and then store the glycogen in the muscles. Then, later on, this stored glycogen helps to produce ATP – a high-energy fuel used by the muscles during any high-intensity exercises.

All the weight gainer supplements are rich in carbs, which will help you to replenish the glycogen stored inside the muscles, especially after a workout.

Great post-workout meal

A post-workout meal is very important for your body because, after a workout, your muscles need immediate recovery.

That is because when you do workouts your muscle tissue breaks and it takes time to repair again.

Therefore for that recovery, you need to eat good nutrition, especially good quality protein and carbs, so that your muscles can recover quickly in the next 24 hrs.

You need to eat protein and carbs after your workout because protein helps to repair the muscle tissues and carbs will help to replenish the glycogen store.

A Weight gainer or Mass gainer contains a good amount of calories, carbs and protein that makes it a perfect choice for a great post-workout meal.

Blend of Macronutrients and micronutrients in a single drink.

Generally, people think that the weight gainer is all about increasing calories intake and gaining weight, but there is more to them than just that.

In some weight gainers with carbs, protein, and fats, you will also get vitamins, minerals, and fibers.

Generally, to get all these nutrients we need to eat a well-balanced diet. But in a single drink of weight gainer supplement, you will get all these important nutrients together.

If you don’t have time to eat your meal then you can replace it with this healthy nutritious drink. Because it’s a blend of all the essential nutrients.

Therefore, choosing the best weight gainer supplement that contains micronutrients is very important for skinny guys.

It’s convenient and easy to use

Weight gainer or Mass gainer is convenient and easy to use and it can be a great replacement for meals.

For example, suppose – If you don’t have time to cook your food or maybe you are traveling and can’t prepare your meal, then you can easily replace your meal with a weight gainer supplement.

It is easy to use also, you just need to add the supplement powder with water, shake it and drink it. Finish, you get all the essential nutrients and calories in a single drink.


Disadvantages of Weight gainers

As we all know not everything in this world is perfect Right?. Everything has its good and bad sides.

Same in weight gainers also. Along with good sides and it has some bad sides too.

Therefore, it’s important to know the proper information and details [Pros and Cons] before buying and using any product.

So keeping that thing in my mind I have listed some disadvantages of using weight gainers or mass gainers.

So here they are:-

  • Some mass gainers may be too high in sugar levels, which can be bad for your body.
  • Sometimes weight gainer supplements can cause stomach problems like bloating, gases, cramps, and pain.
  • Some weight gainer supplements can have a lot of creatine, which can affect your kidneys in the long run.
  • Some weight gainer supplements may contain a lot of caffeine, which can cause dehydration.
  • If you take weight gainer supplements in excess amounts, then it can cause you unhealthy weight gain. It can increase unnecessary fat in your body. [You want to gain weight with Muscles, not with Fats, Right?].

Therefore while taking weight gainer supplements, it is very important to stick with the recommended label (which is given on the label of all the weight gainers).

Don’t try to exceed the recommended amount, as it can cause some side effects in the long run.


What to look for while selecting the Best Weight Gainer for skinny guys – A Proper Buying Guide

learn-to-select-best-weight-gainer-for-skinny-guys

Here are some important aspects to look for while selecting the best weight gainer supplement for skinny guys in 2021

Good Macro split

While selecting the best weight gainer supplement you must look at the macro split. Means carbs to protein ratio.

The carbs to protein ratio must be 2:1 or 3:1 [Maximum], not more than that.

Suppose, if a weight gainer supplement provides 200-300 grams of carbs and 50-100 grams of protein, then it’s ok.

But on the other hand, if it’s providing 300 grams of carbs and less than 50 grams of protein then its macro split is not good.

This type of bad macro split weight gainer supplement can cause you unhealthy weight and fat gain.

In all the weight gainer supplements, the quantity of carbs is higher, as compared to protein, and it’s ok.

But you need to select that supplement with carbs and protein ratio of 2:1 or 3:1[Max]. The quantity of protein should be almost half of the carbs.

Always try to find a weight gainer supplement with high protein content and that can be the best supplement for you.

Because from high protein weight gainer supplement you can get good quality calories, which will help you in a healthy weight and muscle gain.


Quantity of protein

Protein is the building block of muscles.

Our body needs protein especially after a workout to repair the muscle tissues – so that they can get recovered quickly in the next 24 hrs.

Without taking enough protein throughout the day, it’s impossible to build muscles and gain weight.

Therefore while selecting the best weight gainer it’s very important to look at the protein content.

Always try to select a weight gainer supplement with high protein content. At least the quantity of protein should be almost half of the carbs.


Carbohydrates

After a workout along with protein, you also need carbohydrates to replenish the glycogen store.

Moreover, carbohydrates also give energy to the body throughout the day, to perform daily physical activities.

Carbs are present in all weight gainer supplements and the quantity of carbs is always more than the protein.

But always try to select a weight gainer supplement with carbs and protein ratio of 2:1 or 3:1[Max].


Fibre

Fiber is a very important part of the nutrient in your diet.

It helps to clean your system by pushing out all the toxins from the body.

It also helps in proper digestion, constipation, controls cholesterol, blood sugar levels, and many more.

There are many health benefits of fiber. But they are often neglected in daily diets.

Therefore, while selecting the best weight gainer supplement for skinny guys, make sure that the supplement contains fiber.


Vitamins & Minerals

Vitamins & Minerals are essential micronutrients that your body needs, but they are also often neglected in daily diets.

Vitamins help your body to produce energy, boost your immune system, and many more functions.

Minerals help in making your bones, muscles, and heart strong, they also help in producing enzymes and hormones in the body.

Therefore, when buying a mass gainer supplement make sure that your supplement contains some essential vitamins & minerals.


Ingredients

Most weight gainer supplements are quite similar, but the major difference is in the quality of the ingredients that the supplement is made of.

While selecting a great quality weight gainer supplement make sure to look at the ingredients that make up the powder.

You need to choose a mass gainer which is high in complex carbohydrates, protein, fiber, vitamins, minerals and low in sugar, sodium, and processed ingredients (like Maltodextrin and Dextrose).

Generally, high-quality supplements have better water solubility, effectiveness, and cost.

Ideally, high-quality supplements have high prices as compared to low-quality ones.

You will get what you pay for…Right?


Low Sugar levels

While selecting the best weight gainer supplement make sure that it has low sugar content.

Many of the cheap and low-quality mass gainer supplements may have high sugar content instead of beneficial nutrients. Because it is cheaper and easier for the manufacturer to process.

Sugar also easily increases the number of calories in a supplement, which may look good on the label. But actually, it’s not good for your health to take high sugars.

Taking high sugar for a long time may lead to serious health problems and increase body fat.

Therefore before buying any mass gainer supplements, make sure it has low sugar content and high in other beneficial nutrients.


Low Maltodextrin levels

While selecting the best weight gainer supplement for skinny guys make sure it contains low maltodextrin levels.

Generally, maltodextrin is a white powder made from rice, corn, wheat, or vegetable starch that is used in many weight gainers to improve the shelf life and flavor.

Maltodextrin is a fast-digesting carb and is high on the Glycemic index (GI). That means it can raise your blood sugar levels and is especially bad for diabetic patients.

So watch out for low maltodextrin levels in a weight gainer supplement, if you have a problem in taking highly processed carbs.


Creatine

Creatine helps your body to produce more energy during high-intensity exercises.

Many athletes and bodybuilders take creatine supplements before their workout so that they can perform better during their workouts.

Studies have shown that it can increase overall performance, muscle mass, and strength at the gym.


Digestive enzymes

Digestive enzymes help in digestion and breaking down all the foods you eat.

It is important to have digestive enzymes in mass gainers because all the carbs and protein mixture can make your stomach bloated.

Therefore if it is present in mass gainers then it will help in proper digestion and will prevent bloating, gases, cramps, and pain in the stomach.


Taste and flavour

Generally, all the mass gainers taste bad, and that’s the reality.

But you want your mass gainer to taste good and drinkable, Right. You don’t want to drink a shake that tastes weird and nasty.

Therefore, you need to select a weight gainer supplement with good taste and flavor.


Price

You get what you pay for, Right?.

Good quality products will be expensive and bad quality products will be cheap, and that’s the reality.

Therefore, before buying a weight gainer supplement it’s important to check the price – whether it’s an expensive or cheap product.

If you can’t afford the expensive product then go for the mid-range product. But don’t go for the cheapest product in the market.

Because cheap mass gainers will have low-quality ingredients, bad nutritional value, and be less effective. Therefore, it will be a total waste of money.

If you can’t afford mid-priced mass gainers then I will suggest you – Go with real food, which will be a better option than buying low-quality mass gainers.

What is the number 1 weight gainer supplement?

There is no best supplement in the market. Every supplement is best at its place. Every supplement has its different Pros and Cons.

Therefore you need to select a supplement according to your needs (looking at its pros and cons) and select which supplement will ultimately suit you the most.

But still, if you ask me which weight gainer supplement is the best one, then according to me it’s – Naked Mass Natural supplement (For bulky gains) and BSN True Mass (For lean bulky gains).

I like these 2 supplements because the quality of calories and ingredients are good, as compared to other weight gainer supplements.

They contain a good amount of protein and high-quality complex carbs that will help you in a healthy weight gain.

How to use a weight gainer or mass gainer supplement?

Generally, all weight gainer supplements come with detailed instructions on how to use them.

The best way is to check the instructions provided by the company or vendors and follow those.

But still, a common way to drink a mass gainer supplement is by mixing the powder with water or milk. You can also add some fruits or make smoothies to increase the nutrients and calories intake.

Should I take Mass gainer with milk or water?

You can take mass gainers in both ways.

If you don’t have a problem using dairy products and want to increase your calories intake, then you can take a weight gainer supplement with milk.

Otherwise, water is the best and common option to go with.

When to take a weight gainer supplement?

Generally, you can take a weight gainer supplement at any time when you feel hungry or empty.

But if you want to get the full benefits of a mass gainer supplement then I will recommend you to drink after your workout (post-workout).

You need protein and carbs after your workout because protein helps to repair the muscle tissues and carbs will help to replenish the glycogen store.

A weight gainer supplement contains a good amount of carbs, protein and calories that make it suitable to drink especially after workouts.

Similarly, you can also drink a weight gainer supplement in between your meals or can replace it with your meal.

Shall I take a mass gainer supplement before or after a workout?

You must take the mass gainer supplement after your workout. Not before your workout.

It is not advisable to take weight gainer supplements before your workout because these shakes are high in calories and many people may feel bloated after drinking them.

You don’t want food sitting in your stomach during a workout. You have to make sure that whatever you have eaten before a workout is digested properly.

Can I take the weight gainer supplement at breakfast?

Yes, you can.

If you don’t have time to eat your breakfast then you can easily replace it with a weight gainer supplement. It will give you energy throughout the day.

Can I take the weight gainer supplement before bed?

Yes, you can take the weight gainer supplement before bed especially for those who have a fast metabolism and low body fat.

Just make sure to take the weight gainer supplement 1hr before going to bed.

Shall I take the weight gainer supplement on rest days?

Generally, always try to get as many calories as possible from the food instead of supplements.

But still, if you are not getting enough calories from food on your rest days also, then taking a weight gainer supplement can help.

But make sure to decrease the quantity of the supplement according to the needs of the calories – (Maybe use half of the serving instead of a full serving).

Can I take a weight gainer supplement without working out?

Yes, you can take a weight gainer supplement without working out, but it’s not advisable.

It is because if you take a weight gainer supplement without doing any exercise then it will increase your overall body fat percentage.

An increase in body fat is not healthy at all. Over time it can cause some serious health problems. (You need to gain weight in the form of muscles instead of fat).

If you want to gain weight healthily and cleanly, then along with taking a weight gainer supplement you need to do some exercises (weight training) and need to eat a balanced diet.

Will weight gainer supplements make you fat?

Yes, it can make you fat if you are taking a weight gainer supplement without doing any kind of exercise or workouts.

So make sure to do some workouts and eat a healthy well-balanced diet to gain weight in the form of muscles, not fats.

Is a weight gainer supplement a source of good quality calories?

Some weight gainer supplements are and some aren’t.

You can check by looking at the label (ingredients) of the supplements.

A good source of quality calories means – The calories should come from good quality protein (whey or casein proteins), Complex carbohydrates and healthy fats.

Therefore, if you want a good source of quality calories from your weight gainer supplement, then make sure to check for all these healthy macronutrients before buying.

Are Weight Gainer supplements worth it?

Weight gainer supplements are high in calories and are specially made to increase the overall calories intake, which is very important to gain weight.

So if you are a skinny guy or underweight and you are not getting enough calories from foods then a weight gainer supplement is worth it for you.

Weight gainer vs Protein powder, Which one is best for skinny guys?

If you want to gain weight and bulk up fast, then a weight gainer supplement will help you.

On the other hand, if you want to grow and maintain your muscle mass then a protein powder supplement can help you.

Protein powder supplements are generally used to fill up the daily protein needs and requirements.

They are also very low in calories as compared to weight gainers. Therefore, a protein powder supplement can not help you to gain weight fast as much as a weight gainer would.


Conclusion

If you are still confused about which weight gainer supplement is best for skinny guys, then let me help you to make your decision easy.

If you are a very skinny or hard gainer or extremely underweight then you can pick a high-calorie supplement like Naked Mass Gainer.

Similarly, If you want to do lean bulking or if you want to be in moderate surplus and primarily rely on foods to gain weight, then you can go for the BSN true mass.

I like these 2 supplements because the quality of calories and ingredients are good, as compared to other weight gainer supplements.

They contain a good amount of protein and high-quality complex carbs that will help you to gain weight healthily.

Other weight gainers are also quite good and you can go for those also, according to your needs and requirements. It’s all up to you.
