As always, the suitability of tomatoes will depend on your specific needs. Keto dieters will vary in their macronutrient goals and their overall calorie intakes. Those factors, along with your diet as a whole, will influence how regularly you can eat tomatoes.

Other Diets and Tomatoes
Tomatoes are a whole food that doesn’t go through any processing. So, they’re perfect for many other types of diet.
This means you can include tomatoes in any whole foods-based diet. They’re also powerful for raw food approaches, as tomatoes are an effective way to add flavor.
The Mediterranean diet also heavily relies on tomatoes as an ingredient.
You can also use tomatoes to decrease carb or calorie intake, by using them as alternate ingredients or snacks. For example:
- Try cherry tomatoes as a fast and easy snack, rather than chips or fruit.
- Consider a Caprese salad rather than a sandwich. Serious Eats has some fantastic tips for making a perfect Caprese salad every time.
- Use tomato-based sauces for pasta, rather than ones that are heavy in cream or fat.
When Tomatoes Aren’t Suitable
Tomatoes work well on most diets. But, they are nightshades (along with eggplants, peppers and potatoes).
People with an autoimmune condition, food sensitivity or food allergy may be sensitive to nightshades. Cutting them out can sometimes help to improve any related illness.
Reactions to nightshades can include migraines, digestive upset and joint pain.
Because of this, many elimination diets don’t allow tomatoes in some stages.
- For example, Chloe from How We Flourish talks about the inclusion of nightshades in the GAPS diet and why it might be best to exclude them.
- The AIP diet also eliminates tomatoes.
- Some authors argue that tomatoes should be avoided on a paleo diet too because of the potential negative impacts. But, most paleo food lists (like this one) do include tomatoes.
- Other people choose to avoid nightshades because they are sensitive to them, even if their diet doesn’t call for that decision.
The site Ruled.me offers additional details about what nightshades are and why they may be significant.
Other Low Carb Fruits and Vegetables
Tomatoes are one example of a low carb vegetable (or fruit). But, there are plenty of other low carb options too.
Any low carb or keto diet will need to rely on a range of options. Doing so gives you the optimal combination of nutrients and flavors. Besides, the best recipes use many different plant-based ingredients to create complex and nuanced flavors.
Some other popular examples of low carb plant-based options include the following (numbers are net carbs per 100 grams):

- Cabbage (3.3 grams). Cabbage is most commonly included in salads and pairs well with tomato. There are many different varieties to choose from, including some that look particularly spectacular.
- Cauliflower (2.8 grams). Cauliflower is a versatile low carb ingredient. You’ll often see it as a low carb rice alternative or used to re-create high carb recipes like pizza. There are also many unusual cauliflower rice recipes that rely on the vegetable.
- Cucumber (3.1 grams). Cucumber works well as part of a salad along with tomato and other ingredients. You’ll sometimes see it used as an alternative to bread in some recipes. There are other creative uses too.
- Green beans (3.7 grams). Green beans might seem simple, but they add an appealing flavor and texture to many recipes.
