Cherry tomatoes, beefsteak tomatoes, grape tomatoes…the variety seems nearly endless! With so many delicious tomatoes, how can you know if some are better for you on a keto diet? Read on, hungry reader, and I’ll tell you all you need to know about tomatoes on a keto diet!

Are Tomatoes Keto?

Yes….but….

There are a few different kinds of keto. There’s strict keto and what others call lazy keto, and even dirty keto.

Many strict keto dieters will avoid tomatoes because they do have a slightly higher carb count. And that’s fine; it’s a personal choice.

If you’re counting carbs and other macros, then tomatoes can easily fit into your keto lifestyle.

So the simple answer is yes, tomatoes are keto friendly.

How Many Tomatoes Can I Eat?

If I had a nickel for every time someone asked me, “Are tomatoes OK on keto,” I’d be rich! Well, OK far from rich, but you get the point.

The beauty of keto is that as long as you eat under a certain number of carbs each day, your body will stay in ketosis. That’s the goal! Staying in ketosis means your body is burning fat for fuel.

Sure, tomatoes have carbs, but as long as you count them and stay under that number of carbs, then you’re fine!

One cup of cherry tomatoes has about 4 net carbs in it, so don’t go crazy!

Are Cherry Tomatoes Keto?

Yes! Cherry tomatoes are totally keto, but like every other kind of tomato, just be sure to count the carbs!

There are so many delicious tomato recipes, like this Tomato & Cucumber Salad, that are a bit heavier on carbs so just eat a smaller portion or account for them in your daily total.

Are Tomatoes Keto Friendly? How Many Can I eat?

This is a tough question to answer – it all depends on your macros!

How many carbs can you eat each day? Most people aim for about 20 net carbs per day. Let’s say you eat:

  • that leaves 10 net carbs for dinner.

If you enjoy 1 cup of cherry tomatoes, that’s about 4 net carbs, leaving 6 net carbs for the rest of the meal.

Tomatoes Are Very Nutritional

Tomatoes are loaded with nutrition!

  • Tomatoes are packed with an antioxidant called lycopene which is linked to a reduced risk of cancer and heart disease
  • They are vitamin and mineral rich
  • They are high in fiber (and what ketoer can’t use more fiber?)
  • and more!

Is Tomato Sauce Keto?

The problem with tomato sauce is that commercial products are generally LOADED with sugar.

The North American palate, in particular, has grown accustomed to the sweetness of sugar, and now it’s in everything.

And, sugar is often used to balance the acidity of tomatoes.

You’ll find sugar in canned tomato and marinara sauces, pizza sauce, and even in some cans of diced tomatoes. Always read the nutrition labels carefully, watching for hidden sugars like:

  • fructose
  • glucose
  • corn syrup
  • maltose…and more.

Homemade is Best – control those carbs!

You can control the number of carbs that are in tomato and pizza sauce by making your own, and here are a few recipes to get you started:

Are Tomatoes Keto if They’re Cooked?

Yes! Some cooked tomato recipes, like tomato sauces, are more concentrated so the carb count will be a little bit higher. Just account for the carbs and watch your serving size and you’ll be fine. In fact, tomatoes even show up in my weekly Meal Plans!
