How to Gain 10 Kg Weight in 15 Days

Struggling with being skinny is one of the toughest challenges that you can get through. No matter how much you eat and how hard you train, you just can’t seem to put on any sort of weight which can get pretty demotivating. When that happens, you either end up accepting this curse for the rest of your life or setting unrealistic goals by looking for the quickest way to gain weight. This is the exact same reason why a lot of people ask me this interesting question: “How can I gain 10 Kg weight in 15 days?”

Although gaining 10 kg weight in 15 days is impossible, setting it as an ambitious goal is a good idea that will speed up your weight gain process and make your progress much easier since you’ll be eating a lot more calories and pushing your body to its limits.

In this article, we’ll talk about if it’s possible to gain 10 kg weight in 15 days, and why setting it as a goal is a good idea. 

Is it Possible to Gain 10 Kg Weight in 15 Days?

How to Gain 10 Kg Weight in 15 Days

Before answering this question, I want to explain the sole purpose of this website which will help you understand the context of my answer. In this blog, I always tend to be as transparent as possible and not sell you any false information for my personal benefit. I always thrive on sharing what really works and what doesn’t based on my own experiences. 

Unlike what many other websites and “gurus” might tell you, gaining 10 kg weight in 15 days is simply not possible no matter what way you look at it, and here is why:

Scientific explanation

Let’s break it down the scientific way. Gaining 10 kg in 15 days means that you’ll need to gain 0.66 kg per day (approximately 1.4 lbs). And as we all know, the most efficient method to gain weight is by having a calorie surplus (eating more than what your body needs so that the excess is stored as fat). Now, the question on everybody’s mind: “What is the maximum amount of weight that you can put on per day using this method?

Let’s take a look at this research done by The American Journal of Clinical Nutrition. In order to find out the maximum amount of weight that you can put on per day, they overfed a bunch of people 50% more than what their bodies needed every single day for a duration of two weeks (So a calorie surplus of about 1300 calories on average). 

The results that they got will probably shock you. After two weeks of constant overfeeding, all the people ended up gaining only about 1.3 kg (3 pounds) of weight on average. 

If we break down the numbers, that’s a gain of about 0.1 kg per day (0.2 pounds) which is a decrease of 84% from the ambitious goal of 10 kg in 15 days.

Why It’s a Good Idea

As you can see, gaining 10 kg in just 15 days is impossible and it will take you at very least 4 months of constant overfeeding (this rate is only applicable if you have a calorie surplus of about 50% every single day). However, as I mentioned in the beginning, it’s a good idea to have that goal in mind. 

Humans are complex creatures that are always looking for challenges to overcome which is the exact same reason why we tend to set unrealistic goals in our life. Gaining abs in just a week, getting rich in only a month, or becoming the next sensation that will change the world are all ambitious goals that will probably never happen but we keep pinning them in our minds since It’s a pattern that repeats every single day.

And setting these objectives isn’t useless, on the contrary, it’s a good way to work harder in order to achieve them which is why thinking that you can gain 10 kg in 15 days is a good start towards your weight gain journey.

If you just say “I want to gain 1 kg in a month”, you’ll only work towards achieving that simple goal, but if you say “I want to gain 10 kg in 15 days” you’ll put on more work, stay motivated, and get as close to it as possible by the end of those 15 days. 

How to Gain 10 Kg in 15 Days

So now you probably understand that when I say “how to gain 10 kg in 15 days” what I really mean is “how you can get as close as possible to that goal”. Realistically, if you keep that ambitious goal in mind and follow the right methods, you’ll probably end up gaining about 1 to 2 kg in that duration which is more than enough to kick-start your weight gain transformation journey, and here are these methods:

Calorie Surplus

Throughout the whole article, you saw me mention this term quite a lot since it’s a key element that will play a huge role in gaining any sort of weight. As we all know, not eating enough calories is what causes skinny people to stay skinny. If you’re struggling with being skinny, that’s the main reason behind it, you think that you’re eating enough but in reality, you’re not even getting to 60% of what your body needs. 

And in order to gain weight, not only will you need to reach 100% of what your body demands in terms of calories, but you’ll also need to surpass that amount by about 50% every single day. 

If your body needs 2500 calories per day, you’ll need to be consuming 3750 calories. To know the exact number of calories that you need, you can use a calorie calculator

In addition to that, you need to stick to this calorie surplus and maintain it throughout the whole period. If you manage to do so, I guarantee you that you’ll be able to gain at least 1 kg in those 15 days (It’s not as impressive as 10kg but it’s about as close as you can get).

Remember, the key point here is that you’re not eating enough even though you think you do, so track those calories, split your calorie intake into 4-5 meals per day to make it easier for your body, eat every 3 hours, and maintain the same routine every single day. 

Diet

Don’t think that just because you need to reach a certain amount of calories per day that you can eat whatever you want. If the only way to maintain a calorie surplus is through junk food, then it’s okay during the first couple of days to get your body used to that huge increase in calorie intake in a fun way (but keep it limited to only the first couple of days). 

After that, stick with a healthy high-calorie diet that contains all the necessary nutrients that your body needs (proteins, carbs, and healthy fats). Not only will it increase your weight in a healthy way, but it’ll also help you to develop healthy habits which will benefit you in the long term.

Get Stronger

If you’re not looking to only gain fat, then it’s probably a good idea to start some form of resistance training, especially weight-lifting since that will build muscles and make you stronger at the same time. Remember to always lift heavy, focus on those compound movements and full-body workouts, and never skip a workout.

Track Your Progress

Always make sure to track your progress during your weight gain journey since knowing if you’re getting bigger, stronger, or skinnier will keep you motivated to work towards that goal.

Track your calories, weigh yourself every single week, and don’t forget to take pictures to have accurate measurements since mirrors are subjective. 

Conclusion:

Even though gaining 10 kg in just 15 days is impossible, setting it as a goal is one of the best things that you can do for your weight gain transformation journey. The bigger the goal, the more hard work you’ll put in, and slowly but surely, you’ll get close to it in just a couple of months.
