Short answer: No, baked beans are not keto-friendly. A standard cup (240g) contains approximately 38g of net carbs, which exceeds most daily keto limits (20-50g). Even a half cup has 21g of net carbs and 12g of added sugars. Although beans offer nutritional benefits to a standard diet, their high carbohydrate content makes them incompatible with a regularly consumed ketogenic diet.
Baked beans are a British breakfast staple, but their high carbohydrate content makes them incompatible with a ketogenic diet. Understanding why can help you make informed low-carb lifestyle choices.
This article dissects the nutritional profile, explains the science behind net carbs, and offers keto-friendly alternatives that provide similar satisfaction without interfering with ketosis.
Important points
Standard baked beans contain 37-38 g net carbs per cup, exceeding most daily keto limits Added sugar (12 g per half cup) significantly increases carbohydrate content Green beans (2 g net carbs per half cup) make a keto-friendly alternative A modified keto approach may allow for smaller portions with careful planning Homemade versions allow better control of sugar and carbohydrate content
Understand the basics of the ketogenic diet
In a ketogenic diet, your body changes from using glucose to burning fat for fuel through a metabolic state called ketosis. This requires strict carbohydrate restriction.
Daily macronutrient requirements
Standard keto macros include:
Fat: 70-80% of daily calories Protein: 20-25% of daily calories Carbohydrates: 5-10% of daily calories (20-50g net carbs)
Net carbohydrates are calculated by subtracting fiber from total carbohydrates. Fiber doesn’t increase blood sugar levels, so it doesn’t count towards your daily limit.
Baked beans nutritional profile
Green beans simmered in tomato sauce form the base of traditional baked beans. Commercial varieties typically have added sugar, molasses, or corn syrup, greatly increasing the carbohydrate content.
Carbohydrates and sugar content
A half cup (130 g) of standard baked beans contains:
Total Carbs: 27g Dietary Fiber: 6g Net Carbs: 21g Added Sugars: 12g Protein: 6g
One cup provides approximately 38 g of net carbohydrates. This is 76-190% of your daily keto intake depending on your goals.
Brand Type Carbohydrate (per 100g) Net Carbs (per 100g) Ketogenic Compatibility Standard Supermarket 5-7g 15-18g Ultra Low Carb 2-3g 10-12g Medium Homemade Version 0-1g 8-10g Best Choice
micronutrients and minerals
Besides macronutrients, baked beans also provide:
Vitamin B6: 10% DV Magnesium: 8% DV Iron: 10% DV
Verdict: Are baked beans keto-friendly?
No, baked beans are not keto-friendly to consume on a regular basis. Carbohydrate content exceeds most people’s daily limit, and added sugar provides no nutritional benefit to ketosis.

Additional health considerations
added sugar and sodium
In addition to net carbohydrates, commercial baked beans contain high levels of sugar (12g per half cup) and sodium. These additives can affect:
Blood sugar regulation Blood pressure Overall metabolic health
Antinutrients in legumes
Beans contain natural compounds that can interfere with nutrient absorption.
Phytate: Binds to minerals such as iron and zinc Lectin: Can cause digestive discomfort in sensitive people Protease inhibitor: Blocks protein-digesting enzymes
Proper soaking and cooking greatly reduce these compounds, but they are still a consideration for people with sensitive digestive systems.
Keto-friendly bean alternatives
green beans
Green beans are the best choice among keto-friendly legumes, containing only 2g of net carbs per half cup. Use in the following cases.
Stir-fried garlic and almonds Side dishes roasted in olive oil Soups and casseroles Fresh salads
black soybean
Black beans provide 5 to 10 g of net carbs per half cup, depending on the brand. However, the amount of carbohydrates varies widely.

High-carbohydrate beans to avoid during the keto diet
The following legumes have too many net carbs for a ketogenic diet.
Bean Type Net Carbs Per Cup Percentage of Daily Keto Allowance Baked Beans 37.9g 76-190% Chickpeas 32.5g 65-163% Pinto Beans 29.4g 59-147% Kidney Beans 29.0g 58-145% Navy Beans 28.0g 56-140%
According to Healthline’s research on bean nutrition, these varieties are not compatible with standard ketogenic approaches.
Low-carb alternative to baked beans
vegetable-based alternatives
Mushrooms (1g net carbs per cup) mimic the meat-like texture below.
Soups and Stews Casseroles Side Dishes
Eggplant (eggplant) absorbs flavor well and has the following benefits:
Baked Casserole Keto Friendly Dips Roasted Sides
protein-based alternatives
Replace the bean with:
Minced meat: perfect for chili-style dishes High-quality sausage: choose a variety with no added sugar Ground turkey or chicken: choose a lean protein
modified keto approach
A cyclical or targeted ketogenic diet allows for strategically high carbohydrate intake.
Cyclic Ketogenic Diet: Re-feed high carbohydrates 1-2 days per week Targeted Ketogenic Diet: Consume more carbohydrates before and after workouts Portion Control: Only tablespoon-sized servings
Observe your individual reactions carefully. Some people can maintain ketosis with slightly higher carbohydrate intake, while others require severe restriction.
Make homemade baked beans that are keto friendly
Create a low-carb version using:
Black soy-based tomato sauce with no sugar added Keto-friendly sweeteners like a blend of erythritol and stevia Apple cider vinegar for added acidity Smoked paprika and mustard for added richness
This reduces net carbs to approximately 8-10 g per serving while maintaining the familiar flavor.
conclusion
Traditional baked beans are not compatible with a ketogenic diet due to their high net carbohydrate content (38 g per cup). Although it provides nutritional benefits to a standard diet, the carbohydrate load inhibits ketosis.
Green beans are a great keto-friendly alternative with 2g of net carbs per half cup. Other options include mushroom, eggplant, and protein-based alternatives that provide similar texture and satisfaction.
Those following a modified keto approach may be able to consume small amounts (1-2 tablespoons) of homemade, reduced-carb versions and still fit within their daily limits. Always prioritize whole-food keto ingredients that support your metabolic goals.
