Cherries, with their sweet and juicy flavor, are a popular snack. However, if you're following a ketogenic diet, you might be wondering whether they fit into your low-carb lifestyle. Let's dive into the facts about cherries, their nutritional content, and how they might (or might not) fit into a keto meal plan.
Understanding the Keto Diet
The ketogenic diet, commonly referred to as the “keto” diet, is a high-fat, moderate-protein, low-carb eating plan designed to shift your body into a state called ketosis. In ketosis, your body burns fat for energy instead of relying on carbohydrates. This metabolic state is achieved by drastically reducing your daily carb intake and increasing fat consumption.
Over the last century, the ketogenic diet has been widely used as a medical or therapeutic diet due to its potential benefits for conditions like epilepsy. Additionally, in more recent years, research into the keto diet has shown other potential health benefits, such as weight loss and improved metabolic health, particularly in those with Type 2 diabetes and obesity.
However, it’s important to note that the long-term effects of the keto diet and its impact on diet quality require further research. Because of the strict nature of the keto diet and the need for further research, it is recommended to speak with your healthcare provider or registered dietitian before starting to ensure safety and efficacy. If you are currently following a ketogenic diet for medical reasons, please consult your healthcare provider before making any changes.
Staying in Ketosis: Carb Limits
Staying in ketosis requires keeping your carb intake low enough to avoid spiking your blood sugar and insulin levels, which can pull your body out of this metabolic state. For most people, this means consuming fewer than 50 grams of carbs per day, though it varies between individuals. The general recommendation is to keep total carbohydrate intake below 50 grams per day to maintain ketosis.

Within the ketogenic diet community, there is some debate around whether to use net carbs versus total carbohydrate content when calculating and tracking daily carb intake. Net carbs are calculated by subtracting dietary fiber (and, if present, half the sugar alcohol content) from total carbs. This calculation assumes that fiber and sugar alcohols are not absorbed or metabolized, which is not always the case. Oftentimes, these components are partially digested and may impact blood sugar levels.
It’s important to note that the term “net carbs” does not have a legal definition and is not recognized by the American Diabetes Association. Additionally, the Food and Drug Administration (FDA) recommends using total carbohydrates on the nutrition facts label to determine how each food affects your body. On the other hand, many experts still promote the importance of tracking net carbs to maintain ketosis.
Nutritional Breakdown of Cherries
Now let’s take a look at the nutritional breakdown of cherries. Cherries are celebrated for their natural sweetness and abundance of antioxidants, but how do they measure up nutritionally for a ketogenic diet? According to the USDA, one cup of pitted red cherries contains about 19 grams of total carbs, including approximately 13 grams of total sugars. While these sugars are naturally occurring, they still count toward your daily carb intake, which can add up quickly on a ketogenic diet.
When you account for the dietary fiber in pitted cherries, which is roughly 3 grams per cup, the net carb count comes out to about 16 grams per cup. For those aiming to stay under the 50 grams per day, this is a significant portion of the daily limit.
Cherries vs. Other Keto-Friendly Fruits
Certain fruits, like strawberries, raspberries, and blackberries, are often considered more suitable for a ketogenic diet due to their lower “net carb” counts. For example, half a cup of raspberries contains only 3 net carbs.

Here's a comparison of net carbs per serving for some keto-friendly fruits:
- Strawberries: 8.2 g net carbs per cup
- Raspberries: 6.7 g net carbs per cup
- Blackberries: 6.4 g net carbs per 150g serving
- Avocado: 1.3 g net carbs per ½ fruit
- Olives: 4.5 g net carbs per cup
As you can see, cherries have a significantly higher carb count compared to these options.
Can You Eat Cherries on Keto?
The answer isn't a simple yes or no. Cherries can fit into a keto diet, but only in moderation. Here's what to consider:
- Portion Control: A single cup of cherries contains a significant amount of carbs, potentially taking up almost all of your daily allotment.
- Net Carbs vs. Total Carbs: Decide whether you're tracking net carbs or total carbs, and factor that into your decision.
- Individual Tolerance: Carb tolerance varies from person to person. Some individuals may be able to handle a small serving of cherries without being knocked out of ketosis, while others may need to avoid them altogether.
Tips for Including Cherries in Your Keto Diet (If You Choose To):
- Small Servings: Limit yourself to a very small serving size, such as a quarter or half a cup.
- Track Your Intake: Carefully track your carb intake for the rest of the day to ensure you stay within your limits.
- Choose Wisely: Opt for tart cherries, which are slightly lower in carbs than sweet cherries.
- Consider Alternatives: If you're craving fruit, prioritize lower-carb options like berries.
The Benefits of Cherries
Even though cherries are relatively high in carbs, they offer several health benefits:
- Antioxidants: Cherries are rich in antioxidants, particularly flavonoids and anthocyanins, which help protect against cell damage.
- Fiber: Cherries provide a good source of fiber, which can help you feel fuller for longer.
- Vitamins and Minerals: Cherries contain essential vitamins and minerals, including vitamin C and potassium.
- May Aid Sleep: Tart cherries are a source of melatonin, which may aid with sleep.
- Reduce Inflammation: Studies show they may help reduce inflammation, exercise-induced muscle soreness and lowered blood pressure.

- Avocado: Very low in carbs and high in healthy fats.
- Berries (Strawberries, Raspberries, Blueberries): Lower in carbs than many other fruits, and packed with antioxidants.
- Lemons: Can be used to add flavor to dishes and drinks without significantly impacting carb intake.
- Tomatoes: Often used as vegetables, but are fruits that are keto-friendly in moderation.
- Kiwifruit: A person on a keto diet may only want to eat kiwifruit on rare occasions.
