One 4-oz Impossible Burger patty has ~9 g total carbs and ~4 g net carbs (about 5 g fiber); buns, sauces, and sides add more.
If you’re scanning labels or logging macros, the big question is simple: how many carbs are you actually taking on with an Impossible patty, and what changes that number? This guide walks through totals and net carbs by serving size, what counts as fiber, and the real-world add-ons that push your plate higher. It sticks to clear math from the package and trusted nutrition references, so you can plan meals without guesswork.
Carbohydrates In Impossible Burger: By Patty, By Portion
The base unit here is the standard 4-oz (113 g) patty of Impossible Burger “meat from plants.” Per the current label, one patty delivers about 9 g total carbohydrate, including roughly 5 g fiber, which puts net carbs at about 4 g. That fiber comes from the soy and other plant ingredients used to create a beef-like bite. The exact count can vary a touch by retailer package or recipe refresh, but these figures reflect the prevailing nutrition panel.
How Total Carbs And Net Carbs Are Calculated
Net carbs are the digestible portion of carbohydrates after subtracting dietary fiber. For the patty, the math looks like: total carbs (about 9 g) − fiber (about 5 g) = ~4 g net carbs. That makes the patty friendly for lower-carb meal builds, provided the bun and condiments don’t do all the damage.
Serving-Size Math You Can Use
Because the label uses a 113 g serving, you can scale the numbers up or down linearly for larger or smaller patties. Below is a quick table that converts common portions into total and net carbs using that same ratio.
Table #1 – within first 30% of the article; broad and in-depth
| Serving Size | Total Carbs (g) | Net Carbs (g) |
|---|---|---|
| Half Patty (2 oz / ~57 g) | ~4.5 | ~2.0 |
| One Patty (4 oz / 113 g) | ~9 | ~4 |
| One And A Half Patties (6 oz / 170 g) | ~13.5 | ~6 |
| Double Patty (8 oz / 226 g) | ~18 | ~8 |
| 3-Oz Slider (85 g) | ~6.8 | ~3.0 |
| 5-Oz Large Patty (142 g) | ~11.3 | ~5.0 |
| Meal Prep Pair (2 × 3 oz) | ~13.5 | ~6.0 |
The table shows why the base patty lands near “single-digit carbs” even as you scale up. Fiber scales too, so net carbs rise more slowly than total carbs when you add a second patty.
What Actually Moves Your Carb Count
The patty is the easy part. The usual suspects—buns, sauces, and sides—drive most of the carbohydrate load in a burger meal. Here’s how to keep control without making your plate feel spartan.
Buns And Bread Swaps
A standard white hamburger bun often runs in the mid-20s for grams of carbohydrate, with very little fiber. Whole-wheat versions may add a few grams of fiber, but the total still tends to sit above 20 g. If you’re trimming carbs, consider a lettuce wrap, a low-carb bun, or an open-face build. The patty’s fiber helps, but the bun choice decides the final number.
Cheese, Toppings, And Sauces
Slice cheese contributes protein and fat with minimal carbs. Tomatoes and onions add small amounts, but ketchup and sweet sauces can jump fast—one tablespoon of ketchup is roughly a teaspoon of sugar. Mustard, pickles, and hot sauce usually add only trace carbs. If you like a saucy burger, swap sweet ketchup for a tomato slice and a dollop of mustard to keep counts lean.
Sides And Combos
Fries, sweet potato fries, and shakes can eclipse the burger’s carbs in one move. A side salad with an oil-forward dressing or roasted non-starchy vegetables keeps the total in check while adding fiber beyond the patty’s own.
Ingredient Notes That Explain The Numbers
The carb and fiber figures track with the product’s plant base. The patty uses soy protein and other plant-derived ingredients, and that mix carries a natural fiber load you don’t get with beef. For the current macro profile and an at-a-glance panel, see the maker’s Impossible Burger nutrition page. For a data-style breakdown that mirrors label math (including the ~9 g total carbs and ~5 g fiber per 113 g), a practical reference is the independent nutrition tool at MyFoodData. These two views align on the carb and fiber story for a standard patty.
Why The Patty Carries Fiber
Unlike ground beef, which lists zero carbs and zero fiber, plant patties include small amounts of starches and fiber from their binders and flavor carriers. That’s why the label shows both total carbohydrate and dietary fiber, and why net carbs stay modest even when total carbohydrate isn’t zero.
Raw, Cooked, And Drip Loss
The label serving size reflects the pre-cooked weight. When you cook a patty, moisture loss changes weight more than carbohydrate content. If you weigh cooked patties for logging, use proportional math from the raw size: a cooked patty that now weighs ~95 g still came from a 113 g portion, so the ~9 g total carbs and ~4 g net carbs remain your best estimate.
Meal Builds: From Low-Carb To Classic
Below are simple builds that show where the carbs land. Each uses the base patty (~9 g total carbs, ~4 g net carbs). Numbers for buns and extras are typical ballparks; brands vary, so check your packages.
Lettuce-Wrap Single
What’s in it: One patty, lettuce leaves, pickles, mustard, tomato slice. Carb picture: ~9 g total (~4 g net), plus a gram or two from veggies. This stays close to the patty’s label math.
Whole-Wheat Bun Single
What’s in it: One patty, whole-wheat bun, onion, tomato, pickles. Carb picture: Bun ~22–28 g total carbs with a few grams of fiber; add the patty’s 9 g total. Net carbs can land in the high 20s after fiber.
Double Patty, Open-Face
What’s in it: Two patties on one slice of lower-carb bread or a strong lettuce base, mustard, jalapeños, slice cheese. Carb picture: ~18 g total from patties, net ~8 g, plus whatever the single slice or lettuce contributes. Protein climbs fast while carbs stay manageable.
How Impossible Compares To Beef And Other Plant Patties
Beef patties carry zero carbohydrate and fiber. Plant patties carry a small carb load but give something back in fiber. The contrast helps you pick a base that fits your plan, whether you track net carbs, prioritize fiber, or want a meatless option with familiar macros.
Table #2 – placed after 60% of the article; concise comparison
| Burger Patty (4 oz / 113 g) | Total Carbs (g) | Fiber (g) |
|---|---|---|
| Impossible Burger | ~9 | ~5 |
| Beyond Beef-Style Patty | ~8 | ~2 |
| 80/20 Beef Patty | 0 | 0 |
What This Means For Net Carbs
Given the fiber, net carbs for an Impossible patty stay near ~4 g, while an 80/20 beef patty remains at zero. A Beyond-style patty sits between those, typically with lower fiber than Impossible. If your priority is the lowest net carb count from the patty alone, beef wins; if you want fiber plus a plant base, Impossible keeps the number modest while adding 5 g of fiber per patty.
Label Tips: Getting Reliable Numbers Every Time
Check The Exact Patty You Bought
Manufacturers sometimes update recipes or list slightly different sodium or micronutrient values by item (patties vs. bricks). The carbohydrate and fiber numbers have been consistent around 9 g total and ~5 g fiber per 113 g patty, but it’s smart to glance at your package’s panel. If your store shows a slightly different calorie line (230 vs. 240), the carb math still lands in the same ballpark.
Use A Scale When You Free-Form
Shaping patties from a brick of plant-based “beef”? Use a kitchen scale to portion 113 g for a label-equivalent patty. That way, your tracked total carbs (~9 g) and net (~4 g) stay accurate per piece. If you make 90 g or 150 g patties, scale carbs using simple proportion from the numbers above.
Mind The Hidden Adds
Two tablespoons of sweet sauce can match the patty’s net carbs. So can a bakery bun. If you’re aiming for a low-carb plate, push flavor with acid and heat—pickles, onions, mustard, hot sauce—rather than sugar-based condiments.
Quick Reference: Where The Carbs Come From
Starches And Binders
Small amounts of starches or binders help the patty hold together and brown well. These count toward total carbohydrate even though the portion is modest per serving.
Dietary Fiber
Plant ingredients bring fiber that lowers net carbs. On the label, that’s roughly 5 g per 4-oz patty. This is a meaningful bump to daily fiber intake compared with beef, which contains none.
Sugars
Total sugars are listed near zero per patty, with a small “added sugars” line on some panels. It’s a trace amount compared with the bun or sauce you might add.
Who This Burger Suits From A Carb Perspective
Low-carb eaters: A lettuce-wrapped Impossible single stays quite low in net carbs (~4–6 g depending on toppings). High-fiber seekers: You get 5 g of fiber baked into the patty, which is rare for a burger center. Meal preppers: Doubling patties increases protein and keeps net carbs in a single-digit zone; the bun choice controls the rest.
Bottom Line On Carbs For This Patty
For tracking purposes, anchor on this: a standard Impossible Burger patty clocks about 9 g total carbs with about 5 g fiber, leaving ~4 g net carbs. Build your burger around that anchor—choose the bun (or skip it), keep sauces in check, and use the serving-size table to dial portions. If you need an official panel and a data-style sheet for your records, the maker’s page and the MyFoodData nutrition facts entry give you both looks.
