Are Plums Ok to Eat on Keto? Your Complete Carb Guide

4 min read

According to Medical News Today, a whole 75g plum contains 8.5g of carbohydrates and 1g of fiber, yielding 7.5g of net carbs. So, are plums ok to eat on keto, or should they be avoided entirely? This guide will help you understand the carb content and proper portion control to see if they fit your ketogenic lifestyle.

Quick Summary

Plums are moderately high in carbs for a strict ketogenic diet, with net carbs around 6.5-7.5g per medium fruit depending on the source. Small portions may be acceptable if macros are carefully tracked, while dried plums are too high in sugar.

Key Points

  • Plums are a Moderate-Carb Fruit: With a medium fresh plum containing about 6.5-7.5g of net carbs, it's a significant portion of a typical daily keto carb limit.

  • Avoid Dried Plums (Prunes): The drying process concentrates sugars, making prunes exceptionally high in carbs and unsuitable for a ketogenic diet.

  • Portion Control is Crucial: If eating plums, keep portions very small (half or quarter a fruit) and track your macros diligently to stay in ketosis.

  • Opt for Lower-Carb Fruits: Berries like raspberries and blackberries offer more nutritional volume for fewer net carbs and are safer for maintaining ketosis.

  • Consider the 'Carb Investment': For some, the carbs from even a small plum are better spent on more nutrient-dense, lower-sugar keto staples like leafy greens.

  • Balance with Healthy Fats: Pairing a small portion of plum with healthy fats can help slow sugar absorption and minimize impact on blood sugar levels.

Understanding Plums and the Ketogenic Diet

The ketogenic diet, or keto, requires individuals to drastically reduce their carbohydrate intake to put the body into a metabolic state called ketosis. While this often means restricting high-carb foods like fruit, some lower-carb fruits can be consumed in moderation. When considering plums, the central question revolves around their carbohydrate content and how it fits into your daily macro budget.

The Carb Count Breakdown of Plums

Unlike lower-carb berries, plums contain a notable amount of natural sugar. For those on a ketogenic diet, the focus should be on net carbs, which is the total carbohydrate count minus the fiber. Fiber is not digestible and therefore doesn't spike blood sugar levels in the same way as other carbs.

For a medium-sized plum (approximately 65-75g), the carbohydrate breakdown is significant for someone targeting a daily net carb intake of 20-50 grams. The exact numbers can vary slightly, but a typical medium plum provides between 6.5 and 7.5 grams of net carbs. This single serving could consume a large portion of a strict keto dieter's daily carbohydrate allowance.

Fresh vs. Dried Plums: A Macro Comparison

Not all plums are created equal when it comes to the keto diet. The drying process for converting plums into prunes concentrates the sugars, dramatically increasing the carb count. This is a crucial distinction for anyone considering their fruit choices on keto.

Plum Type Carbs (per 100g) Net Carbs (approx.) Keto Friendliness
Fresh Plums 11.4g ~10g Can be consumed in very small, controlled portions
Dried Plums (Prunes) 64g ~61g Should be completely avoided

As the table clearly shows, dried plums are not compatible with a ketogenic diet. A small serving of prunes can single-handedly exceed the total daily carb limit for a strict keto diet, immediately knocking the body out of ketosis. Sticking to fresh plums, and even then, in very small portions, is the only way to potentially enjoy this fruit while on keto.

Can You Fit Plums into Your Keto Diet?

If you have a strict carb limit (e.g., 20 grams per day), a single plum is a significant macro investment. It's not impossible, but it requires careful planning for the rest of your meals. Many keto dieters choose to save their carb budget for non-starchy vegetables that offer a higher nutritional return for their carb count. However, for those with a more flexible low-carb plan (e.g., 50 grams per day), a small plum can be a manageable treat.

Here are some tips for incorporating plums into a keto plan:

  • Consider it a Treat: Don't make plums a daily staple. Reserve them for an occasional reward or a craving for a sweet, juicy fruit.
  • Mindful Portion Control: Eat a half or even a quarter of a plum to minimize the carb impact. Pair it with a high-fat snack like almonds or cheese to help stabilize your blood sugar.
  • Track Everything: Use a food tracking app to meticulously count your net carbs for the day. This is the only way to know for sure if a plum fits within your remaining macros.
  • Timing Matters: Some dieters find it best to eat fruit after a workout when their body is more likely to use the carbs for energy.

Low-Carb Fruit Alternatives to Plums

If the high carb count of plums seems too risky for your ketogenic goals, there are many other fruit options that are lower in net carbs and more keto-friendly.

  • Berries: Raspberries, blackberries, and strawberries are excellent choices. They are lower in sugar and higher in fiber than plums, making them a safer bet for managing ketosis.
  • Avocado: Technically a fruit, avocado is packed with healthy fats and very low in net carbs, making it a keto superfood.
  • Lemons and Limes: These citrus fruits are rarely eaten whole but their juice is low-carb and perfect for adding flavor to water, marinades, and dressings without adding many carbs.
  • Coconut: Fresh or shredded unsweetened coconut is high in healthy fats and is a versatile, low-carb addition to many keto recipes.

Conclusion: The Final Verdict on Plums and Keto

Are plums ok to eat on keto? The short answer is yes, but with extreme caution and in very small, carefully controlled portions. For a strict ketogenic diet, the carbohydrate load of even a single fresh plum makes it a high-risk food that could easily disrupt ketosis. Dried plums, or prunes, are a definitive 'no' due to their concentrated sugar content.

While fresh plums offer beneficial antioxidants and vitamins, they are far from the most keto-friendly fruit available. For those prioritizing ketosis, it is generally safer and more efficient to opt for lower-carb fruits like berries and avocados. Ultimately, for the dedicated dieter, a plum is an occasional treat, not a dietary staple. As always, it's wise to consult with a healthcare professional or registered dietitian before making significant changes to your eating plan to ensure it's appropriate for your health needs.

How to Eat a Plum on Keto

If you choose to enjoy a small portion of plum, consider how to integrate it without causing a carb spike. Try slicing a single small plum thinly over a savory salad with fatty components like goat cheese, nuts, and a high-quality olive oil dressing. This pairing can help mitigate the sugar impact and provides a satisfying contrast of flavors. Another method is to use a very small amount to make a sugar-free plum compote with a keto-friendly sweetener, used sparingly over a bowl of full-fat Greek yogurt. This approach allows you to savor the flavor without compromising your macros. Learn more about keto fruits from Health.com

Frequently Asked Questions

For a strict keto diet with a carb limit of 20-25g per day, it is generally recommended to limit yourself to a very small portion, like a half or quarter of a fresh plum, or avoid them altogether. For a more lenient low-carb approach (up to 50g per day), a single medium fresh plum may be acceptable if carefully tracked.

No, dried plums, or prunes, should be completely avoided on a ketogenic diet. The drying process concentrates the sugar, making prunes extremely high in carbohydrates. Just a small handful of prunes can exceed an entire day's carb limit.

A single plum contains enough carbs to potentially disrupt ketosis, especially if you are on a very strict low-carb diet or have already consumed other carbohydrates that day. It depends heavily on your daily carb limit and overall macro intake.

Excellent keto-friendly fruit alternatives include avocados, blackberries, raspberries, and strawberries. These options are much lower in net carbs and higher in fiber, making them a safer choice for staying in ketosis.

No, plum juice and most plum-flavored products are not keto-friendly. Fruit juices concentrate the sugar and lack the fiber of the whole fruit, leading to a much higher carb load and a significant blood sugar spike.

A medium plum (approx. 7.5g net carbs) is significantly higher in carbs than options like avocado (2g net carbs per cup), raspberries (7g net carbs per cup), and strawberries (8g net carbs per cup). This means you get a much smaller serving of plums for the same carb investment.

While there can be slight variations, the difference in carb content between different fresh plum varieties (e.g., black, red, yellow) is not substantial enough to make one significantly more 'keto-friendly' than another. The key factor is still portion size and overall daily intake.
