Eating Tomatoes on a Keto Diet

Many people might wonder, are tomatoes keto-friendly?

Technically, yes. Unlike most fruits that give too many carbs, tomatoes are the best fruit option for those who are on a keto.

A ketogenic diet means focusing on low-carb foods and the net carb count limit should only be less than 25 grams per day.

How Many Carbs Do I Get When I Eat Tomatoes

One cup serving of raw tomatoes can give around 2 grams of net carbs. 

Also, there are many tomato varieties. Some of these varieties are grape tomatoes and cherry tomatoes.

Regardless of these, the grams of net carbs per serving do not change significantly.

To understand more, take a look at the information below:

  • Roma tomatoes – 4.73 grams
  • Grape tomatoes – 5.51 grams
  • Green tomatoes – 5.1 grams
  • Cherry tomatoes – 4.96 grams
  • San Marzano tomatoes – 4.35 grams
  • Plum (aka Italian) tomatoes – 4.13 grams

Aside from their low-carb content, they are also rich in fiber and beneficial plant compounds.

Are All Tomato-Based Meals Keto?

You might see some of this fruit as the base in some of your favorite keto recipes. However, not all of these foods are compatible with the ketogenic diet.

Remember, not all tomato products can fit a strict keto diet.

For example, if you buy some tomato products from your local store, there might be some additives and extra sugar that can increase the carb content of the tomato product.

Some of these products that contain extra sugar are tomato sauce, salsa, a juice tomato, and canned tomato products.

Some people say that sun-dried tomatoes are keto-friendly but they actually contain more carbs than raw tomatoes. Their total carbs per piece are around 23 grams because of the added sugars in the ingredient list.

Although they are great on-the-go snacks, they can hinder your goal – to achieve ketosis and weight loss.

The main goal of those who are on keto is to keep their bodies under ketosis. To maintain this body process, it is highly advised to monitor your daily carb intake and reduce added sugar intake.

Carbs in Tomato Paste

We all have already tackled, are tomatoes keto-friendly, but how about the paste? Is this fit for the keto lifestyle?

Like tomato sauce, this is also high in carbs. 100 grams can give you around 19 grams of total carbs.

This means that if you eat a small serving of this paste, you can already exceed your daily carb limit and kick yourself out of keto.

To elaborate more, take a look at the information below:

  • One tablespoon of the paste contains 3 grams of carbs
  • One 6-ounce can of the paste contains 32 grams of carbs
  • One cup of the paste contains 50 grams of carbs
  • One tablespoon of this paste contains 18 calories
  • A 100-gram serving of this paste contains 82 calories
  • One 6-ounce can of this paste contains 139 calories

This paste is so thick and condensed. It is processed by stewing the fruit for hours to reduce the water content of the fruit.

The seeds and skins are also removed to make it purer.

If you are on a low-carb diet, you might want to think twice before consuming this.
