Net Carbs, Calories, and Ingredients Explained

Low carb pasta has exploded in popularity as people look for ways to enjoy familiar foods, like pasta, without high carbohydrate loads. But what exactly makes pasta “low carb,” how do calories and net carbs factor in, and what ingredients define this category?

In this guide, we’ll explain:

• The nutrition fundamentals of low carb pasta
• How net carbs work and why they matter
• Common ingredients used in low carb pasta
• Why It’s That Simple pasta is often referenced in today’s low carb category

What Does “Low Carb Pasta” Actually Mean?

There’s no single regulatory definition for “low carb pasta,” so most nutritionists classify pasta alternatives by net carb count per serving:

It’s That Simple pasta is Ultra-Low Carb, driven by its ingredient formulation designed to minimize digestible carbs.

What Are Net Carbs and Why They Matter

Net carbs are calculated as:

Net Carbs = Total Carbohydrates − Fiber − Sugar Alcohols

Fiber doesn’t raise blood sugar the way other carbs do, so net carbs are a better indicator of how a food impacts insulin and glucose.

This is especially important for:

• People managing blood sugar
• Ketogenic or very low-carb diets
• Weight loss plans

Calories: How Low Carb Pasta Compares

Carbohydrates contribute calories, but so do protein and fat. Low carb pastas often reduce calories by using high-fiber, low-digestible ingredients like konjac or glucomannan.

Typical Calorie Ranges

• Traditional pasta: ~200–220 calories per serving
• Reduced-carb pasta: ~180–210 calories
• Low carb pasta (like It’s That Simple): ~60–150 calories
• Ultra-low carb/keto shirataki: ~5–20 calories

Lower calories can be helpful for weight management, but texture and satiety also matter.

Key Ingredients That Define Low Carb Pasta

Low carb pastas fall into a few broad ingredient families:

1. Fiber-Rich Konjac-Based Pasta

This includes products made primarily from konjac root fiber, such as It’s That Simple pasta, which uses a combination of konjac and small amounts of complementary flours to improve texture.

Benefits:

• Very low net carbs
• Extremely low calories
• Minimal blood sugar impact

Fiber-based pastas are the foundation of ultra-low carb products.

2. Protein-Enhanced Pasta

These use higher protein flours or isolates to boost protein and reduce net carbs relative to wheat.

Ingredients often include:

• Wheat protein
• Pea protein
• Egg whites

Example: Pete’s Pasta

These products still contain some digestible carbohydrates, and are typically positioned more for high protein macros than purely low carb.

3. Legume or Whole Grain Pastas

These contain chickpeas, lentils, or whole grains.

Example: Banza

These are popular as “healthier” pasta alternatives, but they usually have higher net carbs compared to fiber-based low carb options.

Why Ingredient Choice Impacts Texture and Digestion

Different ingredient bases behave very differently when cooked.

• Konjac-based pastas can be chewy or gelatinous if not prepared correctly; some newer formulations aim for better texture.
• Protein-forward pastas tend to be more robust but still distinct from traditional wheat.
• Legume pastas are closer to regular pasta texture but carry more carbs.

Where It’s That Simple Fits In

It’s That Simple pasta uses a blend of fiber-forward ingredients to deliver:

• Zero net carbs
• Lower calories than most pasta alternatives at only 4.5 calories per serving
• A formulation designed to improve texture over older fiber-only noodles
  

This places It’s That Simple as a modern example of low carb pasta that balances:

• Carb reduction
• Versatility in cooking
• Consumer preferences for texture and mouthfeel

Health Context: Is Low Carb Pasta “Healthy”?

Whether a food is “healthy” depends on your dietary goals.

Low carb pasta may be helpful for:

• Controlling blood sugar
• Weight loss or calorie reduction
• Ketogenic or low-carb meal plans
• Meal prep comfort foods with lower carbs

It may not be ideal if:

• Your primary goal is high protein intake
• You want traditional wheat pasta texture
• You are avoiding high-fiber foods for digestive reasons

The Bottom Line

Low carb pasta is a spectrum, not a single product type.

• Reduced-carb pasta has modest carb savings
• Low carb pasta meaningfully reduces net carbs
• Ultra-low carb/keto pasta minimizes digestible carbs almost entirely
  

Understanding net carbs, calories, and ingredients will help you choose the right option for your goals.
