Do Teens Need A Weight Gainer Supplement?

Is a weight gainer supplement actually necessary?

While weight gainer powders can be extremely beneficial thanks to how convenient they are for getting in those extra calories, eating real food should always be your number one priority.

Focus on incorporating a variety of whole foods, such as:

• nuts and seeds, including nut butter (peanut or almond butter) andseed butter (tahini, sunflower seed butter)
• healthy oils (coconut, olive, avocado oil)
• whole grains (oats, rice, quinoa, bulgar wheat)
• legumes (chickpeas, lentils, beans)
• fruits and vegetables
• eggs
• yogurt
• chicken, fish, beef

Besides these foods being excellent sources of calories and protein, a well-balanced diet of minimally processed foods will also result in improved overall health – which is key to reaching your fitness goals. For additional advice on gaining weight, check out our diet tips for hardgainers.

If you already follow a generally healthy diet but you’re finding it difficult to gain weight, then a mass gainer could be just what you need for that extra boost to achieve your desired physique.

On the other hand, if your diet is poor, then adding more processed calories probably isn’t the best idea.

What to Look for When Buying a Weight Gainer

Flavor

If you’re going to be consuming a weight gainer regularly for a long time (which is likely the case if you want to maintain your progress), then it’s a huge plus if you can change up the flavors.

Think about it, yes – chocolate ice cream is super delicious, but eating it every single day would quickly result in it losing its novelty – and the same certainly applies to your daily shake.

All of the supplements on this list come in a variety of different flavor options, meaning you can switch to a new flavor (that tastes great) every time you finish the tub.

Know your goals

When choosing a weight gainer supplement, you need to consider your goals and what you’re looking to gain from taking a supplement.

Asking yourself the following question will make your decision easier:

• How many extra calories do I want to consume to achieve my desired results?
• What proportion of my daily calories should be coming from whole foods?
• What are my macro goals? (Do I want the bulk of my calories coming from protein or mostly from carbs?)
• Do I want to use a weight gainer as a regular meal replacement shake or more as an addition to my existing meals? (a high-calorie vs. a low-calorie supplement)

Benefits Of Taking A Supplement To Gain Weight

Convenience: Save Yourself Time

Making a weight gainer shake is undoubtedly a whole lot quicker than preparing a meal. You’ll simply need to add a scoop (or two) of your gainer into some milk or water – and you’re ready for action!

It’s an awesome option if you’re looking for a more convenient way to receive a combination of complex carbs, healthy fats, essential amino acids, as well as vitamins and minerals – without needing to cook the whole time.

As a teen, juggling your studies, strength training, getting enough rest, and ensuring you’re getting enough nutritious calories with the right macro and micronutrients is not easy.

But supplementing with a weight gainer can definitely give you that extra boost that you need to reach your goals.

Easily Reach Your Calorie Requirements

Ever feel like your stomach is a bottomless pit? As in, you really have to eat, and eat, and eat more to put on weight (or even just to maintain your current weight).

Taking a weight gainer supplement is a much easier way to meet your daily calorie needs (eating a lot is hard work) and can be very helpful when it comes to consuming adequate protein to build muscle and prevent weight loss.

In addition, you’ll know the exact macros that you’re getting with each serving, meaning you’ll be aware of how much protein, fats, and carbs you’re consuming – which is essential for making sure you’re eating more calories than your total daily expenditure (TDEE).

More on this below!

Weight Gainer Tips

Muscle growth (and thus weight gain) requires a positive energy balance. This means that you need to be in a calorie surplus – consuming more calories than your body burns.

Here are some pointers to help you build that lean muscle mass quickly, easily, and effectively:

• Use a macro tracker to track your calorie consumption and weight. This will help you dial in your total daily energy expenditure (TDEE). This is crucial. It’s virtually impossible to know if you’re eating enough if you aren’t measuring your progress.
• Calculate your TDEE. Once you know your TDEE, make sure that you eat above it by about 300 to 500 calories per day to gain weight in the most sustainable fashion.
• Up your calories quickly by eating more at each meal and eating more often, whether it means eating more than 3 meals a day, or eating healthy snacks regularly.
• If you’re really trying to bulk up, take your weight gainer powder along with 16 oz of whole milk to add 300 calories and 16 grams of protein per serving.
• You can easily add more calories to your shakes by mixing in some coconut oil, raw honey, oats, nut butter (like peanut butter, almond butter, or cashew butter), and fruit (like bananas or avocado).
• If you’re trying to boost your protein intake without consuming a ton of extra calories, simply add 16 oz of skim milk (or soy milk as a plant-based alternative) to your daily weight-gain powder mixer.

The Verdict

While struggling to gain weight is certainly very frustrating, it doesn’t have to be a challenge!

Of course, you should first focus on improving your diet and consuming enough calories to suit your body’s needs by eating whole foods. However, a weight gainer supplement can certainly make crushing your goals a whole lot more attainable!

For teens on the go, the ultimate weight gainer is Mass Gainer by Transparent Labs.

This high-calorie meal replacement shake is loaded with everything you could possibly want in the perfect weight gainer supplement!

And if you’re searching for a lower-calorie option that’s just as good, try one of the other awesome products on this list, like Clean Meal – Meal Replacement Powder by Kaged.

• a minimum of 25 grams of protein
