In college, I was the skinny guy the big boys would pick on. I would see them coming across the hallway and I would scatter. My dating life was non-existent. My self-esteem was at an all-time low.

I needed to change.

Firstly, I had to work on my self-confidence. This entailed going through several motivational programs. Then I had to gain weight – fast.

To gain weight you need to consume more calories than your body burns. This means filling your diet with more proteins and carbs. This works great for many people but it fails to produce concrete results if you have a high metabolic rate.

The other problem is not everyone has the time to consume more than three meals a day to gain weight. Enter weight gain powders…

These allow you to take in more calories than normal. The powders are consumed as shakes and this contributes to fast absorption rates, unlike solid foods. Most of the weight gainers powders contain more than 1200 kcal per serving.

In this review, I show you some incredible weight gainers powders that you should try out.

Factors to consider when purchasing weight gainer powder

Weight gainers are there for those individuals who want to gain weight fast without consuming too many natural foods. For some people, they have fast metabolic rates that make their bodies burn more foods than they consume.

In other cases, individuals do not have the time to cook and increase their meals.
You need to be extremely careful when selecting supplements because some contain unusual amounts of synthetic ingredients that can cause harm to your body.


This is the first thing you will need to look at. Weight gainers powders supply 600 to over 2000 calories. You have a large content of proteins and carbs with minimal fat content.

The proteins are either whey or casein proteins with the carbs coming from either dextrose or maltodextrin. You need to determine how these top ingredients influence absorption rates.

There should also be a reasonable macro split of proteins and carbs. Most of the weight gainers have 50g of proteins and 200 to 250g of carbs. Fats are usually less than 10g.

The product sheets at the back of the container will show you all the ingredients used on the product. Firstly, you need to calculate how much weight you need to gain. This will then determine the calories to go for. Weight gainer powders’ way of serving is by scoops.

Each product has recommendations on how much you need for each serving. If you are looking at boosting your calorie levels, then you can add some skimmed milk or water to thin the mixture.

It is imperative that you get all your nutrients from multiple sources. Find a shake that comes with vitamins and minerals. This will offer you great value for money. It’s not all about calories as your body needs some minerals and enzymes to enhance absorption rates. Some ingredients even prevent fat buildup.


When purchasing any shake you need to factor in the flavor. Since you will be taking this before or after a workout you need something that can easily go down your throat.

Note that most weight gainers do not have an amazing taste, but some brands have done an impressive job of mixing the powders with flavors like vanilla, chocolate or strawberry. Find a shake that tastes nice as you are going to be taking the mix daily.


Whatever product you purchase should be within your budget. It should offer value for money by letting you get the necessary nutrient content per serving. Most of the weight gainers in the market are not cheap, so you need to set aside some money.

The cheapest products may not necessarily be the best as you may find it hard to digest due to the blunt taste. The most expensive products could come with attractive packaging and a powerful brand name but offer a poor macro calorie mix. It is not easy finding the ideal but checking out online reviews of products can influence your choice.

How much calories to take

Weight gainers come in a variety of calorie amounts ranging from 500 to 2000 kcal. They are designed to supplement an existing diet. The number of calories you go for will be determined by how fast your metabolic rate is and whether you have the time to consume more natural meals per day.

The problem with skinny guys weight gain programs is that they are coming from a place of a calorie deficiency. This means while their target would be to consume 500 kcal per day they need to double this to compensate for the loss of fat.

In addition, someone on a weight gaining program is also doing many exercises that also require additional calories. Calorie calculators will guide the number of calories to add up to your diet to achieve the right body physique.

Grass-fed whey proteins: it has been revealed that cows that feed on grass instead of grain tend to produce beef that has low fats, high vitamin E and A content and has many antioxidants.

The grass-fed proteins also contain healthy fats like omega-3 fatty acids and are known to improve general health. When looking for a weight gainer supplement find one whose proteins are from grass-fed cows.

Benefits of Mass Weight Gainers

When it comes to serving mass weight gainers you will notice that the scoops are large, each having around 300g of powder. Depending on the manufacturer of the product, you can have one or two scoops per serving.

Each bag should take you around two weeks depending on the servings.
People take mass gainers due to the convenience that they offer. If you are looking at gaining over 1000 calories then it can be burdensome to cook all those meals in a day.

It also can be impossible to attain your calorie content when you are traveling. With shakes, all you need is scoop some and mix with water or skimmed milk and you are done.

After an intense workout, your muscles become damaged. That is why you feel tired. To help in muscle recovery after post-workout sessions, you need a high nutrient diet. Weight gainers come with the right amount of proteins, carbs, and minerals to help in this recovery.

Difference protein gainers vs. mass gainers

Most people will find it confusing choosing between the two. Protein gainers as the name suggest boosting your protein intake. They also tend to have lower calorie content unlike the mass gainers – mostly around 100 kcal.

Mass gainers are for those who want to gain weight fast. They will have a mix of carbs, proteins, and fats. The calorie content goes from 500 to 2000 kcal.
When to take your shakes

This is a frequently asked question and the answer is – it will depend on a number of factors. Firstly, how busy are you? If your day is so busy that you will not have enough time for complete meals, then it is prudent you take your shakes during breakfast.

But, the best time to take your weight gainer shake is after a strenuous workout. At this point, your body has spent most of its energy reserves and your muscles need sugars for recovery. It is not recommended to do it before a workout as this will leave your stomach bloated from all the carbs.

If your body has a high metabolic rate and you have low-fat content, you can take the shakes an hour before bedtime. It should not be immediately when going to bed as the excess calories will only be stored as fat.

What you put to your shakes will also depend on how much calorie content you desire to get. If you want more you can mix it with some skimmed milk or bananas. If you want something thin and easy to swallow then use just water. The powders themselves tend to be very thick, so adding more milk to them makes the final product thicker.


When you engage in weight gain program, you come to realize that it is burdensome. You need to add calories fast, but you lack time to fix meals. Weight gainer supplements come with high-calorie content to supplement your diet.

You can take them, first thing in the morning or in the evening. If you discover that you need more calories, you can blend your shake with bananas or skimmed milk. Most of the supplement flavors are off, so this requires you to be particular with the flavor as you will be taking the supplement daily.
