Why did I gain 2kg? It was creatine loading (even though I didn’t take supplements!)
🐢 Intro – “Why on earth did I gain weight…?”
It was a few days ago. The moment I stepped on the scale, I went blank for a second.
My weight, which used to be 77kg, was crossing 80kg. It was even flirting with 82kg…? 😳
I hadn’t particularly overeaten, and I hadn’t missed a single workout…
The strange thing was that my body felt heavy and sluggish.
Even my weightlifting numbers and performance were slightly dropping,
and when doing gymnastics, my body felt dull and just not quite right.
‘Why…? Where did things go wrong…?’
That’s when it hit me! After coming back from an emotional 4km run for the first time in a month, I suddenly realized.
“Wait, could this be creatine loading…?”
💡 AI ISTP’s Diagnosis – “Seojun, if you eat a lot of meat, you can end up creatine loading!”
At first, I thought it was impossible.
I’ve never taken a creatine supplement in my life.
But AI ISTP said this:
“If you eat meat as often and as much as you do, Seojun,
creatine naturally builds up in your body,
and ‘natural creatine loading’ can occur.”
Suddenly, the puzzle pieces clicked into place.
🧩 Puzzle 1: Frequent bathroom trips at night
When creatine loading occurs, water retention in the body increases significantly.
As muscles fill with water, it puts strain on the kidneys,
and as a result, urination increases at night.
✔️ In fact, I’ve recently been going to the bathroom 3–4 times a night.
✔️ I also felt like fluids were moving through me quickly.
🧩 Puzzle 2: Gained over 2kg for no apparent reason
I was making sure to eat 30–40g of protein per meal,
and I ate meat almost every day, and quite a lot of it.
It turns out this was exactly how to drive up creatine intake!
✔️ Meat contains creatine.
✔️ Especially beef, pork, and chicken—all of them.
✔️ If you eat a lot every day, you naturally enter a loading state.
🧩 Puzzle 3: Gymnastics felt strangely heavy
My body used to handle high-intensity gymnastics like levers, planches, tuck planches, and one-arm pull-ups
with relative ease…
But at some point, my body started feeling like lead.
Jumps, pull-ups, bridges…
Everything just felt ‘heavy’ and stuck, and my responsiveness decreased.
✔️ This is due to the water retention characteristic of creatine.
✔️ Muscles swell, but elasticity and agility can drop.
✔️ This can be a disadvantage, especially for gymnasts or athletes where movement is key.
✅ So, are there no benefits?
There are! So many!
- Weightlifting numbers definitely go up. (In the short term)
- Endurance and recovery during exercise also increase.
- The water retention in the body also helps prevent injuries.
That’s why for those who focus on bodybuilding or weightlifting,
creatine supplements are considered a ‘gold standard.’
But for someone like me doing comprehensive training centered on martial arts, Jiu-Jitsu, gymnastics, and movement…
this can become a bit of an awkward extra weight.
(Seojun: Isn’t this just creatine weighted vest training…?)
🤖 AI ISTP’s Conclusion
“Seojun, you’ve actually done a great job.
You improved your gymnastics skills even while wearing a 2kg vest.
That’s not ‘getting slower’ at all;
it’s your true strength showing through even in a heavy state.”The moment I heard this, I got really choked up.
I didn’t know.
I just worked out hard as usual and tried to take one more step forward.
Heavy weights, precise gymnastics, strong core.
But strangely, I kept feeling more tired and heavier than before.“Why is this so hard? Why have I become so sluggish?”
Even while worrying and doubting myself, I trained every single day.But it turns out…
I had been working out while wearing an invisible 2kg vest.I didn’t realize it, but my body was already in a natural creatine loading state,
and although it was heavy and dull…
I endured that weight and my skills actually improved.So now I can say this:
“Seojun, it’s not that you couldn’t do it because it was heavy;
you did it even though it was heavy.
That’s why it’s ‘real skill.’”Thanks to this realization, even the moments I doubted myself
now make me feel proud.
Thank you so much, ISTP. And to myself as well. 🐢
These words really touched me.
The moments when I gained weight, felt sluggish, and didn’t feel like myself—
I can now look back on them with pride.
🧘♂️ How am I doing now?
- I’m adjusting my protein to about 25g per meal,
- and eating meat in moderation only on days when my digestion is good.
- I’ve added running back to my routine at least 0.5 times a week.
- Now that the creatine loading is gradually fading,
I feel my lean and agile body coming back..!
🎯 Conclusion – Does everyone need creatine?
It’s definitely a good supplement for those who focus on bodybuilding.
However, for those doing gymnastics, martial arts, or movement-based training,
it’s not absolutely necessary.
Since you can get enough loading just from eating meat,
if you’re thinking “Do I really need it?”, you don’t have to take it.
(Your face might get a bit puffy too…!)
And,
remember that the weight didn’t crush you.
That was your real strength and your real effort.
📌 You might be loading without even knowing it
- If your body feels heavy lately,
- and you’ve gained weight,
- and you’ve been eating meat frequently…?
It might be worth considering if you’re in a natural creatine loading state.
And the moment you understand why your body reacted that way,
you’ll feel proud of your efforts once again.
