Searching for a straight answer to this question? You've probably already gotten vague responses — from Google, from AI tools, from the back of a pasta box. "It depends." "Check the label." "Generally under 10 grams." None of that actually helps you make a decision.

Here's the real answer.

Low-carb pasta should have 5g or fewer net carbs per serving. Zero carb pasta — the gold standard — has 0g. That's it. That's the number.

Most products calling themselves "low carb" don't come close to meeting that threshold. And It's That Simple pasta? It has zero net carbs per serving. Not 3g. Not 1g. Zero.

First: What Are Net Carbs?

Net carbs are the carbohydrates your body actually digests. The formula:

Net Carbs = Total Carbohydrates − Dietary Fiber − Sugar Alcohols

Fiber passes through your system without spiking blood sugar. Sugar alcohols like erythritol have minimal glycemic impact. What's left after subtracting both is what actually counts toward your daily carb limit and what matters for ketosis, blood sugar control, and weight loss.

For pasta, this distinction is massive. Regular wheat pasta has 37–43g of net carbs per cooked cup. That number barely moves even with "whole wheat" versions.

So What's the Real Low-Carb Threshold?

There's no FDA definition for "low carb." Brands exploit that gap constantly. But clinical nutrition and the keto community have landed on a clear consensus:

5g or fewer net carbs per serving = low carb.

Here's how common pasta options stack up:

Anything above 5g per serving (no matter how the packaging reads) will cut into your daily carb budget fast. Two servings of a "low-carb" pasta with 8g net carbs is already 16g. That's most of your daily keto allowance, before a single vegetable.

Why Most "Low-Carb" Pasta Doesn't Actually Qualify

Chickpea pasta is a common trap. It sounds clean, high-protein, wholesome. But chickpeas are starchy legumes. Chickpea pasta typically carries 28–35g of net carbs per serving. That's not low carb; that's a blood sugar spike dressed up in wellness branding.

The same goes for many "protein pastas" made from lentils, edamame, or pea flour. Higher protein than regular pasta? Yes. Low carb? No.

"Reduced carb" pastas made from wheat blends usually land around 20–25g of net carbs. That's lower than traditional pasta, but "lower" and "low carb" are not the same thing.

The only pasta ingredients that can actually deliver low-carb or zero-carb results are:

• Konjac / glucomannan (the ingredient in It's That Simple)
• Soluble corn fiber
• Allulose-based formulations

These substrates are high in fiber, low in digestible carbohydrates, and don't spike blood sugar — which is exactly why It's That Simple is built on them.

What Makes It's That Simple Different

It's That Simple pasta is made with konjac, a root vegetable whose primary carbohydrate is glucomannan — a soluble fiber the human body cannot absorb. The result: every gram of carbohydrate in It's That Simple pasta is fiber. Fiber that gets fully subtracted from the net carb equation.

That means 0g net carbs per serving, regardless of how much you eat.

• No wheat. No grains. No legumes.
• Available in spaghetti, fettuccine, penne, and more.
• Works with any sauce: bolognese, marinara, pesto, carbonara.
• No math required. No carb budget eaten up.

When pasta is a regular part of your low-carb lifestyle, zero net carbs isn't just a better number. It's a fundamentally different eating experience. You don't track it. You don't portion-stress it. You just eat it.

How to Read Any Pasta Label in 4 Steps

Before buying any pasta that claims to be low carb:

1. Find Total Carbohydrates on the Nutrition Facts panel.
2. Subtract Dietary Fiber.
3. Subtract Sugar Alcohols (subtract erythritol fully; subtract maltitol cautiously; it has a higher glycemic impact than it's given credit for).
4. Check the serving size. A product with 4g net carbs per 56g dry serving becomes 8g if you eat what most people consider one bowl.

With It's That Simple, you can skip all four steps. The answer is always 0g.

The Bottom Line

Low-carb pasta means 5g or fewer net carbs per serving. Zero carb pasta means 0g. Most products marketed as low carb don't meet either standard. They're simply lower than regular pasta, which is a very low bar.

If you want pasta that genuinely works within a keto or low-carb lifestyle without eating up your daily carb budget, the answer is It's That Simple. Zero net carbs, real pasta shapes, no compromises.

FAQS

How many net carbs should pasta have to be considered low carb?

Low-carb pasta should have 5 grams or fewer net carbs per serving. For keto diets, the ideal range is 0–2 grams of net carbs, with zero net carb pasta being the most reliable option for staying within daily carb limits.

Is 10g of net carbs considered low-carb pasta?

No, pasta with 10 grams of net carbs is not considered low carb. While it’s lower than traditional pasta, it can quickly exceed your daily carb limit, especially on a keto diet, where most people aim for 20–30 grams of net carbs per day.

What pasta is best for a keto or low-carb diet?

The best pasta for a keto or low-carb diet contains 0–2 grams of net carbs per serving and is typically made from konjac (glucomannan fiber), soluble fiber, or allulose. These ingredients are not digested as carbohydrates and do not spike blood sugar.

Why do some low-carb pastas still have high net carbs?

Many products labeled “low-carb pasta” are made from chickpeas, lentils, or pea protein, which are naturally high in carbohydrates. As a result, they often contain 15–35 grams of net carbs per serving, making them unsuitable for true low-carb or keto diets.
