Did you know that you could use protein shakes for weight gain? Whey Protein is comparatively cheaper, more widely available, and easier to mix with your favorite beverage, helping you reach your caloric and protein requirements.
In this article, we share our top 5 homemade protein shakes for weight gain recipes so you know how to gain healthy weight!
What is Whey Protein
While processing cheese from milk products, the water that churns out in the final process is what Whey Protein actually is. In short, the mixture of proteins in the form of liquid that is separated while cheese production is called whey protein.
This liquid goes through numerous processing units and finally the powdered form of whey protein is derived, which is flavorless and can be directly consumed.
It is only then that the additional flavors are added to give is a taste.
Why Do We Need Whey Protein for Weight Gain
There are countless reasons for adopting weight gainer shakes, but we’ll only discuss about the benefits that are related to muscle building and fat loss and how we can use protein shakes to help gain weight.
Recommended: Here are the different types of whey proteins for your understanding.
Protein, which is said to be the building block of muscles, supplies essential amino-acids to the muscle tissues that are damaged while working out. Don’t freak out. Causing micro-tears in your muscle tissues is actually a good thing. Once you take the right nutrition, which includes protein rich foods, they’ll grow better and stronger.
This repeated cycle over a long period of time helps you grow bigger and stronger, which is exactly what we wish to achieve.
To list down some of the important benefits of Whey Protein in muscle are:
- Whey protein promotes muscle growth: As discussed above, whey protein helps repair the muscle tissue damage caused while working out. These tissues then grow stronger and better, helping in overall muscle growth.
- Whey protein helps reduce hunger: Whey protein has shown the highest reduction in hunger as compared to proteins like soy and casein. (Present in casein powder)
- Whey Protein helps lose weight: Since whey protein is found to reduce hunger, it’s an excellent macro-nutrient to help you lose weight.( Don’t worry, this won’t happen here)
- Helps improve body composition: Enough consumption of whey protein in a healthy weight gain diet consequently leads to better lean mass gain, which in turn improves body composition.

Basic Principles For Gaining Weight
The only way your body puts on healthy weight is when it is in a Caloric Surplus.
What this is means is your body needs a specific amount of calories a day in order to function properly. When you supply your body with more than the required calories it needs to maintain your weight, you start gaining weight.
Once you get the optimum amount of calories needed by your body in a day, add 300-500 extra calories per day to gain healthy weight. These extra calories should come from high quality, whole foods that are nutrient dense. (NOTE: More calories does not mean you will gain better weight)

Why Focus Particularly on Protein?
While there are three macro-nutrients required by our body to function, protein is no doubt the most important, especially when it comes to building muscles. Some of the reasons have been mentioned above.
Since muscles are made up of protein, it is important that you consume enough protein to gain healthy weight, in form of quality muscles. If you focus more on carbohydrates and fats, you’re ultimately going to gain just unhealthy extra fat.
While trying to put on healthy weight, aim for 0.7-1 grams of protein per pound of body weight, or twice your body weight in kilograms.
There are multiple ways to include protein in your weight gain diet, out of which eating protein rich foods is the best thing you can do to gain weight safely. Some high quality protein rich foods include Chicken Breast, Whole Eggs, Salmon, Tuna, Dairy Products and Nuts.
Make sure you consume most of your diet in form of whole foods and only use supplements to fill in the gaps. If you’re someone with a good appetite and have access to quality meals throughout the day, it is best to take all most of your protein from whole foods.
The next step is to supplement your diet with a whey protein powder to gain weight.

What about Carbohydrates and Fats?
While gaining healthy weight, carbohydrates and fats are also important macro nutrients that you should keep in check.
Along with the right amount of protein, only focus on eating foods rich in complex carbohydrates and healthy fats. Include foods like Whole Wheat Bread, Dried Fruits, Peanut Butter and Oats which are nutrient as well as high in calories.
TIP: Dried Fruits are a great way to add calories to your diet. Make sure to include them in your diet for extra quality calories.
Shortcut to Gaining Weight – Eat Calorie Dense Foods
Again, gaining healthy weight involves much more than going to the gym and gulping down protein shakes. While a protein rich diet is definitely needed, you also need to focus on the overall nutrition.
Some of my favorite go-to food items to gain weight are:
- Whole Wheat or Multi-Grain Bread
- Whole Eggs
- Oatmeal
- Peanut Butter
- Dried Fruits and Nuts
- Chicken, Meat and Fish
- Sweet Potatoes
- Dark Chocolate
Once you’ve consumed most of your diet using the right quality whole foods, the next step is to focus on weight gain protein shakes for underweight. Let’s be real, no one wants to keep eating right for the rest of their lives.

Having cheat meals actually does good to your body, helping you achieve your fitness goals faster. Hence always remember to give your body little breaks in between, but only once you have strictly followed a routine for quite a time.
Does Whey Protein Alone Make You Gain Weight?
I’ve constantly talked about this topic before, and I’ll always talk about this in the future.
There is NO single food or supplement that can be credited for overall weight gain/weight loss. If you’re approached by a salesman claiming to have a product that does, you’re probably in the wrong place.
How much weight you gain/lose depends on your overall calorie intake and expenditure over a specific period of time.
If you’re constantly losing weight, considering you do not have a medical condition, chances are you’re eating lesser calories than what your body requires in a specific period of time.
Using the above statement, you can conclude a very basic result which can have a huge impact on your fitness journey. If you’re eating more calories than what your body burns in a day, you’d be gaining weight.

When is the Best Time to Take Protein Powder for Weight Gain?

There is no best time to consume a specific food item or supplement. Your overall body composition depends on how much calories you consume over a period of time.
While you may consume whey protein powder anytime throughout the day, post-workout is a great time to replenish and repair muscles after an intense workout.
Try to consume a serving within 30-45 minutes post workout to boost and speed up muscle recovery and gain muscle faster.
