Are Tomatoes Keto Friendly?

A kitchen staple across global cuisines, tomatoes are beloved for their rich flavor, diverse culinary use, and impressive nutritional content. Frequently, a question arises among the health-conscious and those following specific dietary plans: "Are tomatoes keto-friendly?"

From cherry tomatoes sparkled in salads to beefsteak varieties grilled to perfection, where do these vibrantly colored fruits (yes, fruits!) fit within the spectrum of a ketogenic diet? This article delves into the nutritional composition of tomatoes, explores whether they align with the principles of a ketogenic diet, and gives methods to incorporate them effectively into a keto-oriented lifestyle.

What Is the Keto Diet?

What Is the Keto Diet?

The ketogenic diet, or keto diet, is a high-fat, low-carb diet that has taken the wellness world by storm. In 2020 alone, the keto diet was searched on Google more than 25.4 million times, which made it the most Googled diet in the United States.

The whole point of the keto diet is to drastically lower your daily carb limit. By doing so, you can put your body into a metabolic state called ketosis, which is where the diet gets its name. In this state, the body burns stored fat for fuel, which supports weight management and other health benefits.

While that might sound simple enough, determining which foods are keto-safe can be incredibly difficult. Many foods, including tomatoes, contain carbohydrates, which means eating them on the keto diet can be a little tricky.

Each diet is structured around the main three macronutrients of nutrition: fats, protein, and carbohydrates. For most diets, carbohydrates are the primary focus, with protein being the second most important and fats being the least coveted.


However, the keto diet is all about flipping the standard food pyramid on its head. Instead of loading up on carbs, the keto places a higher emphasis on fats and proteins.


Here is a breakdown of the macronutrient profile for a keto diet:

  • 70-75% of total daily calories (1,400 to 1,500) from fat, which is between 155 and 167 grams of fat each day.
  • 20-25% of total daily calories (400 to 500) from protein, which is between 100 and 125 grams of protein each day.
  • 5-10% of total daily calories (100 to 200) from carbs, which is between 25 and 50 grams of carbohydrates each day.

Now, it’s important to note that net carbs play a crucial role in determining the overall carb content of a food. Carbohydrates can be divided into two types: digestible and non-digestible.


The digestible ones are sugars and starches, while non-digestible carbs are fiber. Net carbs are essentially the total carbs in a food minus the fiber content. This is because fiber is a carbohydrate that our bodies can't digest.


Despite being non-digestible, fiber is a critical component of our diet. It aids in digestion, helps control blood sugar levels, and can promote feelings of fullness. In the context of a keto diet, fiber is even more important.


Since you're significantly reducing your carb intake, you want to ensure the carbs you consume are high-quality. This is where fiber-rich foods come into play. Foods high in fiber are usually low in net carbs, making them perfect for a keto diet.


Ultimately, fiber doesn't count toward your daily carb intake because it doesn’t impact your blood sugar levels. In other words, you can eat fiber-rich foods without worrying about getting kicked out of ketosis.

Are Tomatoes Keto-Friendly?

According to the USDA, a medium tomato, which is about 100 grams, contains approximately 3.9 grams of total carbohydrates and 1.2 grams of fiber. If you remember our earlier discussion about net carbs (total carbs minus fiber content), this gives us a net carb count of roughly 2.7 grams.

In the context of a ketogenic diet, where the daily carb intake is typically limited to around 20 to 50 grams, a medium tomato's 2.7 net grams of carbs fits neatly within the low daily carb requirements. So, not only are tomatoes keto-friendly, but they are also a nutrient-dense addition to your diet.

Tomatoes are rich in several nutrients that make it an excellent addition to your diet. For example:

  • Tomatoes are nutrient-dense, boasting a high content of vitamin C, a vital nutrient known for enhancing immunity and promoting skin health.
  • They also serve as a good source of potassium, essential for maintaining heart health and fluid balance.
  • Folate, another key nutrient present in tomatoes, plays a significant role in cell function and tissue growth, making it particularly beneficial for pregnant women.
  • The most praised nutrient in tomatoes is lycopene, a potent antioxidant responsible for their bright red color, associated with numerous health benefits, including a reduced risk of heart disease.


So, to answer the burning question: Yes, tomatoes are keto-friendly. These low-carb fruits offer a rich variety of nutrients and a low net carb count, making them a great choice for those following a ketogenic diet.

Whether you enjoy raw tomatoes in salads, diced tomatoes in your favorite keto recipe, or canned tomatoes as a base for a tangy, homemade tomato sauce, tomatoes can add a burst of flavor and nutrition to your meals without breaking your carb bank.
