You’ve been hitting the gym, mixing that chalky white powder into your water every morning, and watching the scale creep up. Then life happens. Maybe you’re going on vacation, or you’re tired of the bloating, or you just forgot to buy a new tub of Creapure. You start wondering: if I stop taking creatine will I lose weight, or am I just going to deflate like a sad balloon?
The short answer is yes. You’ll lose weight.
But it’s probably not the kind of weight you’re thinking of. Most people freak out because they see the number on the scale drop by three to five pounds within a week of quitting. They think they’re losing all their hard-earned gains. Honestly, that’s just not how biology works. You aren't losing muscle that fast. You're just peeing out the extra water your muscles were holding onto.
The Science of the "Creatine Whoosh"
Creatine is osmotic. That’s a fancy way of saying it pulls water into your muscle cells. When you saturate your muscles with creatine phosphate, you’re also increasing intracellular water volume. This is why you look "fuller" or more "pumped" when you’re on it. According to researchers like Dr. Darren Candow, a leading expert on creatine metabolism, this water retention is actually a good thing for protein synthesis.
When you stop? That osmotic pressure vanishes.
Your kidneys catch up. You might notice you’re heading to the bathroom more often for a few days. That’s the "weight" leaving your body. It’s purely fluid. If you were hoping to drop fat by quitting creatine, you’re going to be disappointed. Creatine doesn't contain calories, and it doesn't stop your body from burning fat. In fact, by quitting, you might actually make it harder to maintain the metabolic rate that keeps fat off.
Performance vs. Aesthetics: The Real Trade-off
If you stop taking creatine, the scale goes down, but your gym performance might take a hit too.
Creatine is the primary fuel source for high-intensity, short-duration bursts of energy—think heavy triples on the bench press or a 40-yard dash. It regenerates Adenosine Triphosphate (ATP) faster than your body can do it on its own. Without that supplemental boost, your "top gear" might feel a little sluggish.

You might find that the 10th rep on your final set, which used to be a breeze, is now a struggle. That’s because your phosphocreatine stores have returned to baseline levels. Is this a disaster? No. You can still build muscle without it. But if you were using that extra "oomph" to move heavier loads, your total training volume might dip.
Lower volume can eventually lead to less muscle stimulus. That’s the real risk.
Will You Look Smaller?
You’ll look different.
Because creatine pulls water into the muscle (intracellular) rather than under the skin (subcutaneous), it usually makes muscles look harder and more defined. When you stop, that "pop" fades. You might feel "flat." This is often misidentified as muscle loss. It isn't. Your muscle fibers are still there; they’re just less hydrated.
Think of a grape versus a raisin. The raisin has the same "stuff" inside, just less water.
The Mental Game of Quitting
The psychological impact of seeing the scale drop is weirdly intense for some people. If you’ve spent months trying to bulk up, seeing a 4-pound drop in 72 hours can feel like a failure. On the flip side, if you're trying to cut weight for a wedding or a photoshoot, stopping creatine might give you that leaner, "dried out" look you’re after.
I’ve seen athletes stop using it purely for the mental win of hitting a lower weight class. But they often regret it when their strength drops 5% across the board.

It’s a trade-off.
Why People Think Creatine Makes Them Fat
There is a huge misconception that creatine causes fat gain. It doesn't.
Fat gain requires a caloric surplus. Creatine has zero calories. If you feel "fat" on creatine, it’s usually one of two things:
- Subcutaneous Bloating: If you’re taking a low-quality creatine monohydrate with impurities, or if you’re taking it with a massive amount of high-glycemic carbs (like those old-school "cell-tech" formulas), you might hold water under the skin.
- Digestive Issues: Some people get gastric distress or bloating if they take too much at once, especially during a "loading phase."
When you ask "if I stop taking creatine will I lose weight," you're likely asking because you feel puffy. If that's the case, try switching to a pure micronized monohydrate and skipping the loading phase. Just 5 grams a day. No bloat.
What the Research Says
A study published in the Journal of the International Society of Sports Nutrition highlighted that while creatine increases body mass, that mass is almost entirely lean tissue and water. When subjects stopped, their strength didn't immediately vanish, but their ability to recover between sets slowed down.
Another study by Rawson et al. found that even after stopping, it takes about 4 to 6 weeks for the creatine levels in your muscles to return to their "pre-supplement" state. It’s not an overnight disappearance. Your body naturally produces about 1 to 2 grams of creatine a day anyway, mostly in your liver and kidneys, and you get some from red meat and fish. You’re never truly "empty."
Factors That Influence How Much Weight You'll Lose
Not everyone loses the same amount. It depends on:

- Muscle Mass: The more muscle you have, the more water you hold. A 250-pound bodybuilder will lose significantly more weight than a 120-pound marathon runner when quitting.
- Diet: If you eat a lot of red meat, your natural stores are already higher, so the "drop" might be less dramatic.
- Hydration: If you’re chronically dehydrated, you won’t notice much of a change because you weren't holding the water to begin with.
Practical Steps for Moving Forward
If you’ve decided to stop taking creatine, do it intentionally. Don't just drift off and wonder why your workouts feel "off."
Monitor your strength, not just the scale. Don't freak out when the number drops. Instead, track your lifts. If your bench press remains steady, you haven't lost muscle. You've just lost "the pump."
Adjust your expectations for recovery. You might feel a bit more sore the day after a heavy session. Without the extra ATP support, your muscles are working a bit harder to keep up.
Watch your sodium and carb intake. If you’re quitting creatine to "look leaner," keep an eye on your salt. High sodium will cause the under-the-skin water retention that actually looks bad, whereas creatine water usually looks good.
Consider a lower dose instead of quitting. If you’re quitting because of bloating, try 3 grams instead of 5. You’ll still get most of the cognitive and physical benefits without the "heavy" feeling.
Summary of the "Off-Cycle" Experience
Stopping creatine is a bit like letting the air out of a tire slightly. The tire is still there. It still works. It just doesn't have that same firm grip on the road. You will lose the "water weight" quickly—usually within 7 to 14 days. Your muscles will look slightly smaller in the mirror. Your weight will drop by a few pounds.
But your fat percentage won't change. Your muscle fibers won't wither away. And if you decide to jump back on later, your body will soak it right back up within a week or two.
If your goal is fat loss, keep taking it. The extra strength helps you maintain muscle while in a calorie deficit, which keeps your metabolism high. If your goal is just to see a smaller number on the scale for a doctor's appointment or a weigh-in, then stopping 10 days before the event will do the trick.
Just know what you're losing: it’s water, not work.
Actionable Next Steps
- Record your "day zero" weight and measurements. This gives you a baseline so you don't panic when the scale fluctuates.
- Increase your water intake for the first three days after stopping. This helps your kidneys flush the excess and prevents any "rebound" puffiness.
- Focus on "Mind-Muscle Connection" during your lifts. Since you’ll lose the chemical "pop," you’ll need to focus more on form to ensure you're still stimulating the muscle effectively.
- Evaluate your goals after 30 days. If you feel significantly weaker or slower, consider that the benefits of creatine outweigh the 3-pound weight gain.
