The ketogenic diet, or keto diet, is a low-carb, high-fat eating plan designed to shift the body into a state of ketosis, where it burns fat for fuel instead of carbohydrates. While fruits are generally higher in natural sugars and carbs, some can still fit into a keto diet in moderation. Apples and plums, though delicious and nutritious, pose a challenge due to their carbohydrate content. A medium apple contains around 25 grams of carbs, and a medium plum has about 7-8 grams, which can quickly add up and potentially knock someone out of ketosis. However, smaller portions or lower-carb varieties, like green apples or certain plum types, might be incorporated sparingly, depending on individual carb limits and overall dietary goals.
| Characteristics | Values |
|---|---|
| Apples on Keto | Generally not recommended due to high carb content (about 25g carbs per medium apple). |
| Plums on Keto | Limited consumption possible; small plums (100g) contain ~11g carbs, which may fit into a strict keto diet if portioned carefully. |
| Net Carbs (Apples) | ~21g net carbs per medium apple (total carbs minus fiber). |
| Net Carbs (Plums) | ~8g net carbs per 100g (total carbs minus fiber). |
| Fiber Content (Apples) | ~4g fiber per medium apple. |
| Fiber Content (Plums) | ~1.4g fiber per 100g. |
| Keto-Friendly Alternatives | Berries (e.g., strawberries, raspberries, blackberries) are lower in carbs and better suited for keto. |
| Daily Carb Limit (Keto) | Typically 20-50g net carbs per day. |
| Portion Control | Small portions of plums (e.g., 50g) may be keto-friendly (~4g net carbs). |
| Glycemic Index (Apples) | Medium (38-44), may cause blood sugar spikes. |
| Glycemic Index (Plums) | Low to medium (28-43), depending on ripeness. |
| Conclusion | Apples are too high in carbs for keto; plums can be included in very small amounts if carbs are tracked closely. |

Net Carbs in Apples: Check apple varieties for lower carb counts to fit keto macros
Apples, with their natural sweetness and crunch, might seem off-limits on a keto diet, but not all varieties are created equal in terms of carb content. By focusing on net carbs—total carbohydrates minus fiber—you can identify apple varieties that fit within your keto macros. For instance, a small Granny Smith apple contains about 21 grams of total carbs and 4 grams of fiber, resulting in 17 grams of net carbs. While this might still be high for strict keto, it’s manageable in moderation or as part of a lower-carb day.
When selecting apples for keto, opt for varieties with lower sugar content and higher fiber. Granny Smith apples are a top choice due to their tartness and relatively lower sugar levels compared to sweeter varieties like Fuji or Honeycrisp. A medium Fuji apple, for example, contains around 25 grams of total carbs and 4 grams of fiber, yielding 21 grams of net carbs—a less keto-friendly option. Pairing apples with high-fat foods like almond butter can also help mitigate their carb impact by slowing digestion and stabilizing blood sugar.
Portion control is key when incorporating apples into a keto diet. A whole apple may exceed your daily carb limit, but slicing it into smaller portions can make it more manageable. For example, a 100-gram serving of Granny Smith (about ⅓ of a medium apple) contains roughly 11 grams of total carbs and 2 grams of fiber, resulting in 9 grams of net carbs. This smaller serving can be paired with a tablespoon of almond butter (2 grams net carbs) for a satisfying, keto-friendly snack under 11 grams of net carbs.
Finally, consider the context of your overall daily carb intake. If you’re aiming for 20–30 grams of net carbs per day, even lower-carb apple varieties should be consumed sparingly. Tracking your macros with an app can help ensure you stay within limits. For those with higher carb allowances or following a more flexible keto approach, apples can be a nutritious addition, providing fiber, antioxidants, and hydration. Always prioritize whole, unprocessed apples over apple products like juice or sauce, which are higher in carbs and lack fiber.

Plums and Keto: Small portions of plums can be keto-friendly due to low net carbs
Plums, with their sweet-tart flavor and juicy texture, might seem like a forbidden fruit on a keto diet, but they can actually fit into your low-carb lifestyle—in moderation. A small plum (about 66 grams) contains roughly 7 grams of carbs and 2 grams of fiber, resulting in 5 grams of net carbs. This makes it possible to enjoy a plum without knocking yourself out of ketosis, provided you account for it in your daily carb budget, typically 20–50 grams. The key is portion control: one small plum as a snack or dessert can satisfy your sweet cravings while keeping your macros in check.
To maximize the keto-friendliness of plums, pair them with high-fat, low-carb foods. For example, slice a plum over a dollop of full-fat Greek yogurt or pair it with a handful of macadamia nuts. This not only balances the natural sugars in the plum but also keeps your overall meal aligned with keto principles. Avoid dried plums (prunes), as the dehydration process concentrates their sugars, significantly increasing the carb count per serving.
While plums are lower in net carbs than many other fruits, their impact on ketosis can vary depending on individual tolerance. If you’re new to keto or highly sensitive to carbs, start with half a plum and monitor your ketone levels. Over time, you’ll learn how your body responds, allowing you to adjust portions accordingly. For those in maintenance or less strict phases of keto, a whole plum can be a refreshing treat without derailing progress.
Practical tip: Choose firmer, less ripe plums, as they tend to have slightly lower sugar content. Always track your intake using a keto app or food diary to ensure you stay within your carb limits. With mindful planning, plums can be a delightful addition to your keto diet, offering a burst of flavor and essential nutrients like vitamin C and potassium without compromising your goals.

Portion Control Tips: Measure servings to avoid exceeding daily carb limits on keto
Apples and plums, while nutritious, are naturally high in carbs, making them challenging to fit into a keto diet without careful planning. A medium apple contains about 25 grams of carbs, and a medium plum has around 8 grams. For keto dieters aiming to stay under 20-50 grams of net carbs daily, these fruits can quickly consume a significant portion of their limit. Portion control becomes essential to enjoy them without derailing ketosis.
Step 1: Measure Precise Servings
Invest in a kitchen scale or measuring cups to accurately portion fruits. For apples, limit yourself to 1/4 cup of diced pieces (about 5 grams of net carbs) or a thin slice (2-3 grams). For plums, halve or quarter the fruit to stay within 4-6 grams of net carbs per serving. Eyeballing portions often leads to overestimating, so measuring ensures you stay within your carb budget.
Caution: Beware of Cumulative Carbs
Even small servings of apples and plums add up, especially when paired with other carb sources like nuts or dairy. Track your daily intake using a keto app or journal to avoid exceeding limits. For example, if you have 1/4 cup of apple slices (5g net carbs) and a handful of almonds (2g net carbs), you’ve already consumed 7 grams of carbs in one snack.
Pro Tip: Pair with Fat or Fiber
To mitigate the carb impact, pair small portions of apples or plums with high-fat or high-fiber foods. For instance, dip apple slices in almond butter or serve plum wedges with a sprinkle of chia seeds. This slows digestion, reduces blood sugar spikes, and helps maintain ketosis.
While apples and plums aren’t off-limits on keto, they require meticulous portion control. By measuring servings, tracking intake, and pairing them strategically, you can enjoy these fruits without compromising your dietary goals. Remember, keto is about balance—not deprivation.

Alternatives to Apples: Choose berries or avocados for lower-carb fruit options on keto
Apples and plums, while nutritious, can derail ketosis due to their higher carb content—a medium apple contains 25g carbs, and a plum, 7-10g. For those adhering to a strict keto diet (typically 20-50g carbs daily), these fruits consume a significant portion of the daily allowance, leaving little room for other nutrient-dense foods. Fortunately, alternatives exist that align better with keto principles without sacrificing flavor or nutritional benefits.
Berries emerge as a top choice for keto dieters craving fruit. Raspberries, blackberries, and strawberries are exceptionally low in carbs—one cup of raspberries contains just 7g net carbs, while strawberries clock in at 9g. These fruits are also rich in fiber, antioxidants, and vitamin C, making them a guilt-free snack. Incorporate them into keto-friendly recipes like whipped cream bowls, chia puddings, or as a topping for almond flour muffins. Aim for ½ to 1 cup per serving to stay within carb limits while enjoying their natural sweetness.
Avocados, though often categorized as a vegetable, are technically a fruit and a keto superstar. With only 2g net carbs per 100g, they provide healthy fats, fiber, and essential nutrients like potassium and magnesium. Their creamy texture and mild flavor make them versatile—slice them onto salads, blend into smoothies, or mash for guacamole. For a sweet twist, pair avocado halves with a sprinkle of cinnamon and a drizzle of stevia-sweetened whipped cream. This combination satisfies sugar cravings while keeping carbs in check.
When comparing berries and avocados, their carb profiles and nutritional benefits complement each other. Berries offer a sweet, antioxidant-rich option ideal for desserts or snacks, while avocados provide satiety and healthy fats, perfect for savory dishes or as a base for keto treats. Combining both in your diet ensures variety and maximizes nutrient intake without compromising ketosis. For instance, a morning smoothie with ½ avocado, ½ cup raspberries, unsweetened almond milk, and a scoop of collagen peptides creates a balanced, low-carb breakfast.
Practical tips for incorporating these alternatives include meal prepping berry portions to avoid overeating and storing avocados at room temperature until ripe, then refrigerating to extend freshness. For those tracking macros, use a food scale to measure servings accurately. By prioritizing berries and avocados over higher-carb fruits like apples and plums, keto dieters can enjoy fruit’s benefits while staying aligned with their dietary goals.

Keto-Friendly Recipes: Incorporate apples or plums in low-carb desserts or snacks
Apples and plums, though naturally sweet, can be incorporated into a keto diet with careful planning. Both fruits contain sugars, but their fiber content helps mitigate blood sugar spikes. A small, tart apple (like Granny Smith) has around 15-20 grams of carbs, while a medium plum contains about 7-10 grams. By using these fruits sparingly and pairing them with low-carb ingredients, you can create desserts and snacks that align with keto principles.
One effective strategy is to combine apples or plums with high-fat, low-carb ingredients to balance macronutrients. For instance, a keto-friendly apple crumble can be made by slicing a small apple thinly, tossing it with cinnamon and a tablespoon of almond flour, and topping it with a mixture of melted butter, chopped walnuts, and a sprinkle of erythritol. Bake at 350°F for 20-25 minutes until tender. This dessert keeps carbs in check while providing healthy fats and fiber. Similarly, plums can be halved, stuffed with a mixture of cream cheese and almond extract, and broiled for 3-4 minutes for a creamy, low-carb treat.
When using apples or plums in keto recipes, portion control is key. Limit servings to ¼ to ½ of a small apple or one medium plum per recipe to stay within typical keto carb limits (20-50 grams per day). Additionally, opt for less sweet varieties like Granny Smith apples or damson plums to reduce sugar content. Pairing these fruits with ingredients like chia seeds, coconut flour, or unsweetened coconut flakes can further enhance fiber and healthy fats while keeping carbs low.
For a snack idea, try making keto-friendly fruit chips. Slice apples or plums thinly, sprinkle with cinnamon or a pinch of sea salt, and dehydrate at a low temperature (150°F) for 2-3 hours until crisp. These chips provide a satisfying crunch with minimal carbs. Alternatively, blend ½ a plum with ½ cup of full-fat coconut milk and a teaspoon of vanilla extract for a creamy, chilled dessert. These recipes demonstrate how apples and plums can be enjoyed on a keto diet without compromising nutritional goals.
Incorporating apples or plums into keto desserts and snacks requires creativity and precision. By focusing on small portions, pairing with low-carb ingredients, and prioritizing less sweet varieties, you can enjoy these fruits while staying in ketosis. Experiment with recipes like apple crumble, stuffed plums, fruit chips, or creamy plum pudding to add variety to your keto meal plan. With mindful planning, apples and plums can be a delightful addition to your low-carb lifestyle.
