How to Read Konjac Labels: What “Zero Net Carb” Really Means
f you’ve ever picked up a pack of Shirataki Noodles or Konjac Noodles and thought, “How can food exist with zero net carbs and still be… food?” — congratulations, you are officially smarter than half the internet.
Konjac labels are famous for confusing even the most label-obsessed shoppers. This guide will decode konjac nutrition facts, break down net carbs explained in human language, and help you understand what brands really mean when they claim “zero net carb.”
No fluff. No marketing nonsense. Just truth — with a pinch of humor so you don’t fall asleep mid-fiber explanation.

What Is Konjac Anyway?
Konjac comes from the root of the Amorphophallus konjac plant, native to Asia. Its fiber — called glucomannan — absorbs water like a sponge that just drank a swimming pool.
This fiber is what turns konjac into Konjac noodle, Shirataki fettuccine, and even konjac rice. It’s also the reason these products qualify as a healthy noodle and why your digestive system treats them like polite guests instead of sugar bombs.
Why Konjac Looks Like a Carb but Isn’t
Here’s the trick: konjac is technically a carbohydrate — but it’s almost entirely fiber. And fiber isn’t digested into glucose.
So while the nutrition label might say:
|
Nutrient |
Per Serving |
|
Total Carbs |
4g |
|
Dietary Fiber |
4g |
|
Sugar |
0g |
|
Net Carbs |
0g |
Those carbs cancel themselves out faster than your motivation on leg day.
Net Carbs Explained (Without a PhD)
Net carbs = Total carbs – Fiber – Sugar alcohols (if any)
Since konjac is made of glucomannan fiber, it typically has:
- 3–5g total carbs
- 3–5g fiber
- 0 sugar
- Result: 0 net carbs
That’s why Konjac Noodles, low carb fettuccine noodles, and Shirataki noodles don’t spike blood sugar.
Your body doesn’t absorb the fiber — it escorts it out politely.
The Big “Zero Net Carb” Label — Is It Legit?
Yes. Not magic. Just math.
But brands sometimes make it look suspiciously magical because:
- They round numbers.
- They highlight net carbs instead of total carbs.
- The ingredient list is short and weird (water, konjac flour, calcium hydroxide).
Don’t panic. That’s how konjac works.
How to Read a Shirataki Label Like a Pro
Here’s your shirataki label guide for next grocery trip.
1. Ingredients
You want to see:
- Water
- Organic konjac flour / glucomannan
- Calcium hydroxide (just for texture — not cement, relax)
If it contains wheat flour, starch, or mystery sugars — put it back like a bad Tinder date.
2. Total Carbohydrates
Expect 3–5g per serving.
This is fine. Remember: fiber ninja cancels everything.
3. Fiber Content
This should almost equal total carbs.
If it doesn’t, something fishy is going on — and not in a sushi way.
4. Calories
Typically 10–20 calories per serving. That’s not a typo.
This is why Well lean noodles are trending with keto, diabetics, and people tired of pretending cauliflower rice tastes like rice.

Why People Get Bloating with Konjac
It’s not the noodle’s fault — it’s yours.
Glucomannan expands with liquid. If you eat it dry, rushed, or in heroic quantities, your gut will host a balloon festival.

- Eat like a normal human, not a competitive eater

Marketing Myths You Can Now Laugh At
Myth: “Zero net carbs means fake food.”
Truth: It means fiber-heavy plant root.
Myth: “It’s too good to be real.”
Truth: Asia has been eating konjac for 1,500 years. The only new thing is Instagram.
Myth: “All konjac is the same.”
Truth: Quality matters — texture, smell, and ingredient purity vary wildly.
Final Takeaway
Reading konjac labels isn’t hard — it just looks scary.
If you remember only one thing, remember this:
Konjac has carbs.
Konjac is also almost pure fiber.
Fiber doesn’t count.
Math wins. Waistlines celebrate.
So next time you see Shirataki noodles, Konjac noodles, or Well lean noodles screaming “zero net carb,” don’t roll your eyes.
Just nod wisely — like someone who understands labels better than most nutrition influencers on the internet.
