Tomatoes On Keto

Tomatoes are classified as a fruit by botanists. They are, nevertheless, considered keto-friendly, unlike other fruits.

That’s because, regardless of type, tomatoes have roughly 2–3 grams of net carbohydrates per 3.5 ounces (100 grams), which is up to 10 times less than most fruit.

Net carbohydrates are calculated by subtracting a food’s fiber content from its carb content.

As a result, tomatoes are much easier to stick to the daily carb restriction than other fruits, making them keto-friendly. Other low-carb fruits are similar, such as zucchini, peppers, eggplant, cucumbers, and avocado.

In addition to being low in carbs, Tomatoes are high in fiber and contain a range of beneficial plant chemicals that may be lacking on a strict ketogenic diet. There are two more reasons why you should incorporate them into your keto diet.

Key Points

  • All carbohydrate-rich foods, especially fruit, must be strictly limited to a ketogenic diet.

  • Despite being botanically a fruit, raw tomatoes are considered keto-friendly since they contain much fewer carbs than the same amount of fruit.

  • Sundried tomatoes, like many other prepared tomato-based items, are often sweetened with sugar.

  • Always read the food label to see whether something fits into your keto diet if you’re not sure.


Despite being categorized as a fruit, tomatoes have much fewer carbs than other fruits. As a result, they’re keto-friendly, but the majority of other fruits aren’t.

The Ketogenic Diet is a High-fat and Low-carb

The ketogenic diet is intended to bring your body into ketosis, a metabolic state in which fat is used for energy and ketones are produced as a byproduct.

The ketogenic diet is most typically used to help persons with epilepsy lessen their seizures. It has, however, been linked to several other health benefits, including weight loss, better blood sugar control, and possibly even a healthier heart.

To enter ketosis, your body must move from carbohydrate to fat as its primary fuel source. To do this, your daily carb intake must be reduced to less than 5–10% of your total daily calories, or less than 50 grams of carbohydrates per day.

The decrease in calories is partially compensated by an increase in fat or fat and protein calories, depending on the sort of ketogenic diet you are attempting to adhere to.

Apples and pears, for example, provide about 20–25 grams of carbohydrates per serving. As a result, they are in the same group as other carb-rich foods such as grains, legumes, starchy vegetables, and sugary meals, all of which are forbidden on a ketogenic diet.

Not All Tomato Products are Keto-Friendly

Sugar is frequently added to tomato-based foods, such as:

  • Sauce de tomato

  • Paste made from tomatoes.

  • Juice made from tomatoes.

  • Salsas.


A ketogenic diet encourages you to enter ketosis. You must significantly limit your intake of carb-rich foods, particularly fruit, for this to happen.

A Beginner’s Guide to the Keto Diet and Ketosis

First and foremost, you must comprehend how keto can assist you in losing weight. The goal is to put your body into ketosis, a natural metabolic state where your body burns fat instead of carbohydrates.

This occurs because, on the keto diet, you typically consume 50 grams (g) or fewer carbs per day, according to Deborah Malakoff-Cohen, RD, CDCES, a New York City-based nutritionist.

According to the Cleveland Clinic, the normal keto diet advises you to consume 70 to 80 percent of your calories from fat, 20 percent from protein, and 5% from carbohydrates.

Knowing which fruits to avoid since some have more carbs than others is crucial for expediting weight reduction and reaping other keto benefits.

According to Harvard Medical School, big, long-term, randomized controlled research on the keto diet are scarce, so it’s uncertain whether keto is safe and effective to follow for the long haul.

According to a recent analysis, keto can offer health hazards to some people, including people with type 1 diabetes and type 2 diabetes who are on medication, persons at risk for heart disease, people with renal illness, and women who are pregnant.

According to Tori Schmitt, RDN, and creator of YES! Nutrition in Dayton, Ohio, the so-called keto flu is a possibility (and perhaps likely) for anyone as their body adjusts to ketosis on the keto diet, independent of any underlying health conditions.

The keto flu causes fatigue, irritability, headaches, and nausea, according to Schmitt. Thankfully, the keto flu only lasts one to two weeks. To be safe, consult your doctor to see if keto is good for you.

A study discovered that the lycopene present in tomatoes — the same lycopene that gives them their distinctive red color — can lower a person’s risk factors for cardiovascular disease.

4. Reduction of Cancer Risk

According to a 2010 review, the lycopene in tomatoes may help lower your risk of prostate cancer. Cooked tomatoes are the finest source of lycopene because the cooking process allows the lycopene to escape its fleshy confinement.

Roasting, grilling, steaming, and sautéing are all acceptable methods of preparation. Anything that tears down cell membranes and allows lycopene to run wild can increase the advantages of tomatoes.

According to a study, your helpful, juicy red buddies can also help prevent colorectal cancer cells from spreading.
