Tomatoes On Keto: Friend Or Foe?

The keto diet is a high-fat, low-carb diet that aims to put your body in a state of ketosis, where it burns fat for energy instead of carbohydrates. On the keto diet, you're recommended to get 60 to 75% of your calories from fat, 15 to 30% from protein, and only 5 to 10% from carbs, which typically amounts to less than 50 grams of carbs per day. This means that fruits, which are generally high in carbs and natural sugars, are often off-limits on the keto diet. So, what about tomatoes? Are they allowed on keto?

Tomatoes are keto-friendly

Tomatoes are indeed keto-friendly. While they are technically a fruit, they contain far fewer carbohydrates than most other fruits, which makes them suitable for a ketogenic diet.

The keto diet is a high-fat, low-carb diet that aims to put your body in a metabolic state called ketosis, where it burns fat for energy instead of carbohydrates. To achieve this, keto dieters aim to restrict their daily carbohydrate intake to around 50 grams or less.

Fruits are typically high in carbohydrates due to their natural sugars, so they are often limited on a keto diet. However, tomatoes are an exception. A half-cup serving of standard tomatoes contains only four grams of carbohydrates and two grams of sugar. Even grape and cherry tomatoes, which have slightly higher carb counts, can usually be incorporated into a keto diet without issue.

When following a keto diet, it is important to monitor your carbohydrate intake from all sources, including fruits like tomatoes. However, with their low carb content, tomatoes can be a great way to add variety to your meals while still maintaining ketosis.

It is worth noting that not all tomato-based products are equally keto-friendly. Store-bought tomato sauces, pastes, and canned tomatoes often contain added sugars, which can significantly increase their carbohydrate content. Therefore, it is always a good idea to check the ingredient labels when purchasing tomato products to ensure they align with your keto diet.

Raw tomatoes are best

Tomatoes are a great addition to a keto diet, but there are some things to keep in mind. While tomatoes are technically a fruit, they are treated like a vegetable and can be included in a keto diet. Raw tomatoes are best, as they are typically keto-friendly.

The keto diet is a high-fat, low-carb diet that aims to put your body into a state of ketosis, where it burns fat for energy instead of carbohydrates. Generally, a keto diet involves getting 60 to 75% of your calories from fat, 15 to 30% from protein, and only 5 to 10% from carbohydrates. This usually means limiting your carb intake to less than 50 grams per day, and sometimes less than 20 grams for more strict keto diets.

Fruit is often restricted on a keto diet due to its high carbohydrate and sugar content. However, tomatoes are an exception. A half-cup serving of standard tomatoes contains four grams of carbohydrates and two grams of sugar. Grape tomatoes contain three grams of carbohydrates per half-cup serving, while cherry tomatoes have six grams of carbohydrates and four grams of sugar. These options can fit into your overall carb count and should not be a concern on a keto diet.

When it comes to tomatoes on a keto diet, it is best to choose whole, raw tomatoes. Store-bought tomato products like sauce, paste, salsa, juice, and even canned tomatoes often contain added sugars, which increase the total carb content and make them less suitable for a keto diet. Sundried tomatoes also have a higher net carb content due to their low water content, so they should be consumed in moderation.

So, if you're following a keto diet, feel free to enjoy raw tomatoes. They are a great way to add variety to your meals while staying within the recommended carb limits. Just be mindful of the added sugars in processed tomato products and adjust your intake accordingly.

Tomato sauces are often loaded with added sugar

Tomatoes are considered keto-friendly, but not all tomato-based products are. Many store-bought tomato products, such as tomato paste, sauce, salsa, juice, and even canned tomatoes, contain added sugars. This significantly raises their total carb content, making them less suitable for a ketogenic diet.

The ketogenic diet is a high-fat, low-carb diet that aims to put the body into a state of ketosis, where it burns fat for energy instead of carbohydrates. To achieve this state, the diet restricts daily carb intake to around 50 grams or less. As a result, foods like grains, legumes, starchy vegetables, and fruits are typically limited or avoided.

While raw tomatoes are considered keto-friendly, with around 2-3 grams of net carbs per 3.5 ounces, some tomato-based products can be high in added sugars. These added sugars can increase the total carb content, making it more difficult to adhere to the strict carb limits of the ketogenic diet.

It is worth noting that the carb counts can vary slightly depending on the type of tomato used in the sauce. For example, grape tomatoes have three grams of carbs per half-cup serving, while cherry tomatoes have six grams of carbs and four grams of sugar. However, as long as these fit within the overall daily carb allowance, they can still be included in a ketogenic diet.

When following a ketogenic diet, it is recommended to opt for whole tomatoes and avoid store-bought sauces to minimize the risk of consuming added sugars. By checking ingredient labels and being mindful of portion sizes, individuals can make informed choices about including tomato-based products in their keto diet while staying within their desired carb limits.

Sundried tomatoes are less keto-friendly

Tomatoes are considered keto-friendly, but sundried tomatoes are less so. This is because the process of drying tomatoes removes water, which concentrates the carbohydrates.

A ketogenic diet is a high-fat, low-carb diet that aims to put the body into a state of ketosis, where it burns fat for energy instead of carbohydrates. To achieve this, the diet restricts daily carbohydrate intake to around 50 grams or fewer.

Tomatoes are considered a fruit, but they are keto-friendly because they contain fewer carbohydrates than most fruits. A half-cup serving of standard tomatoes contains four grams of carbohydrates and two grams of sugar. Grape tomatoes contain three grams of carbohydrates per half-cup serving, while cherry tomatoes contain six grams of carbohydrates and four grams of sugar.

However, sundried tomatoes are less keto-friendly because they have a higher concentration of carbohydrates due to their low water content. A cup of sundried tomatoes (54 grams) contains around 23.5 grams of net carbohydrates, which is significantly more than the same serving of raw tomatoes.

Therefore, while raw tomatoes are generally considered keto-friendly, sundried tomatoes should be consumed in moderation or avoided on a ketogenic diet.

Tomatoes are rich in fibre and beneficial plant compounds

Tomatoes are a great source of fibre and beneficial plant compounds. They are rich in cellulose, hemicelluloses, and pectin fibres, which are resistant to intestinal digestion in the large intestine and are believed to improve bowel disorders, cancer, diabetes, cardiovascular diseases, and obesity. Tomatoes also contain chlorogenic acid, caffeic acid, and ferulic acid, which are powerful antioxidants that can reduce oxidative stress and prevent chronic diseases.

Tomatoes are also rich in lycopene, a red pigment and antioxidant that has been linked to improved heart health and cancer prevention. Lycopene is found in the highest concentrations in the skin of tomatoes. It is also found in high amounts in tomato products such as ketchup, juice, paste, and sauce. Consuming lycopene with a source of fat can increase its absorption by up to four times.

In addition to lycopene, tomatoes contain other plant compounds such as beta carotene, naringenin, and chlorogenic acid. Beta carotene is an antioxidant that gives foods a yellow or orange hue and is converted into vitamin A in the body. Naringenin, found in tomato skin, has been shown to decrease inflammation and protect against various diseases in mice. Chlorogenic acid is a powerful antioxidant that may lower blood pressure in people with elevated levels.
