The Problem with Traditional Ketchup on a Low-Carb Diet
While tomatoes themselves are relatively low in carbs, the manufacturing process for most store-bought ketchups dramatically increases their sugar and carb content. To achieve that signature sweet-and-tangy flavor, most commercial brands add high-fructose corn syrup or cane sugar, which are major no-gos on a low-carb eating plan.
A single tablespoon serving of a typical, popular brand of ketchup can contain around 4 grams of carbs, nearly all of which are from sugar. For someone on a strict ketogenic diet aiming for 20-50 grams of carbs per day, a few generous dollops of ketchup can quickly derail their efforts to stay in ketosis. Condiments are often overlooked sources of sugar, and without careful label-reading, they can be a significant setback.
Embracing Low-Carb and Sugar-Free Alternatives
Fortunately, you don't have to give up ketchup forever. The health food market has responded to the demand for low-sugar products, and many brands now offer excellent low-carb and keto-friendly ketchup options. These versions often use alternative sweeteners like stevia, erythritol, or monk fruit extract to provide sweetness without the added carbs.
When shopping for low-carb ketchup, it is crucial to read the nutrition facts and ingredient list carefully. Look for products labeled "no sugar added" or "sugar-free" and ensure that the carb count is 1-2 grams per serving or less. Be mindful of other sweeteners that may still contain carbs and read the labels to avoid those with high-fructose corn syrup.

Making Your Own Low-Carb Ketchup
For ultimate control over ingredients and to avoid any hidden additives, making your own low-carb ketchup at home is a great option. It’s surprisingly simple and allows you to adjust the flavors to your preference.
Here’s a basic recipe to get you started:
- Combine 1 cup of sugar-free tomato paste, 1/4 cup of apple cider vinegar, 2 tablespoons of your preferred keto-friendly sweetener (like erythritol or allulose), 1/2 teaspoon of salt, and 1/2 teaspoon of onion powder, garlic powder, and paprika.
- In a saucepan, whisk the ingredients together over medium heat until smooth.
- Bring the mixture to a simmer, then reduce the heat to low and let it thicken for 10-15 minutes, stirring occasionally.
- Remove from heat, let it cool completely, and store in an airtight container in the refrigerator for up to a month.
Other Low-Carb Condiment Alternatives
If you find that low-carb ketchup doesn't quite hit the spot, there are plenty of other flavorful condiments that are naturally low in carbs and sugar.
- Mustard: Classic yellow mustard and dijon mustard are excellent, low-carb choices that add a tangy kick to your food. Just avoid honey mustard, which is typically high in sugar.
- Mayonnaise: Real, full-fat mayonnaise is a fantastic low-carb staple, made primarily from eggs and oil. Always check the label for added sugars, as some brands include them.
- Hot Sauce: Most hot sauces are low in carbs and can add a lot of flavor with just a few dashes. Check the label to ensure it doesn't contain added sugars.
- Salsa: A fresh, simple salsa made from diced tomatoes, onions, cilantro, and lime juice is a great low-carb condiment.
