The ketogenic diet has surged in popularity across the USA, characterized by a high-fat, low-carb intake. Typically, a keto diet consists of 70-75% calories from fat, 20-25% from protein, and a mere 5% from carbohydrates. While the keto diet has been highlighted for its potential to jump-start weight loss, enhance mental clarity, and boost energy levels, its restrictive nature often leads individuals to seek a more balanced and sustainable dietary approach. Transitioning off keto requires a thoughtful strategy to avoid negative side effects and ensure a healthy, long-term dietary switch.
Understanding the Keto and Mediterranean Diets
The keto diet, originally used as a short-term therapeutic option for poorly controlled seizures, has gained traction as a weight loss strategy. However, limited studies exist on the long-term health impacts of following the keto diet. Some articles suggest that keto can improve glycemic control and reduce heart disease risk, while others point to poor long-term adherence and potential long-term health consequences.
In contrast, the traditional Mediterranean diet emphasizes a rich intake of plant foods like nuts, beans, legumes, and whole grains, along with fish, poultry, limited red meat, unsaturated vegetable oils, and moderate red wine consumption. The macronutrient composition of the Mediterranean diet typically includes 45% to 55% of calories from high-quality carbs, 25% to 35% of calories from fat, and 15% to 20% of calories from lean proteins.
The keto diet is highly restrictive, which can lead to nutrient deficiencies, whereas the Mediterranean diet is more flexible, sustainable, and rich in nutrient-dense, whole foods. While the keto diet prioritizes fat quantity, potentially increasing LDL levels if the right types of fats aren’t consumed, the Mediterranean diet emphasizes fat quality, including heart-healthy monounsaturated fats from olive oil and omega-3-rich polyunsaturated fats from fish and nuts.
Why Reintroduce Carbs?
While the keto diet can be effective for short-term weight loss, its restrictive nature makes it challenging to maintain long-term and may lead to nutrient deficiencies. Reintroducing carbs can offer a more balanced and sustainable approach to nutrition, providing essential nutrients and supporting overall health.

Potential Benefits of Reintroducing Carbs
- Increased Energy Levels: Carbohydrates are the body's primary source of energy. Reintroducing them can help replenish glycogen stores and improve energy levels, especially for those who are physically active.
- Improved Mood and Cognitive Function: Carbs play a role in the production of neurotransmitters that regulate mood and cognitive function. Reintroducing them may help improve mood and mental clarity.
- Better Gut Health: Many carb-rich foods, such as fruits, vegetables, and whole grains, are high in fiber, which is essential for gut health. Reintroducing these foods can help promote a healthy gut microbiome.
- Greater Dietary Variety: The keto diet severely restricts food choices. Reintroducing carbs allows for a wider variety of foods, making it easier to meet nutrient needs and enjoy meals.
How to Safely Reintroduce Carbs After Keto
Transitioning off keto requires a gradual and thoughtful approach to minimize potential side effects and ensure a smooth transition to a more balanced diet.
Gradual Reintroduction
Start by gradually increasing your intake of complex carbohydrates by 10-20g toward your goal amount. The ketogenic diet includes minimal carbohydrates, to which your body has become accustomed. After reintroducing carbs into your diet gradually for the first 2 weeks, start eating the daily amount recommended by your doctor or generally recommended for your age, height, weight, and level of activity.
Focus on Complex Carbs
When looking to incorporate carbs back into your diet after severe restriction, focus on eating carbs that are high in protein and fiber, such as bean-based pasta, crackers with seeds, or sprouted breads. Prioritize complex carbohydrates over simple carbs. Complex carbs have more nutrients and fiber and take longer to digest, preventing blood sugar spikes. Avoid sugar, soda, candy, and highly processed foods. Instead, concentrate on a diet rich in lean proteins, healthy fats, and complex carbs.
Prioritize Protein and Fiber
As you gradually reintroduce carbs into your diet, focus on options that are high in protein and fiber to help you stave off hunger and stomach issues. When adding carbs back into your diet, it’s important that you give your body time to adjust by starting with carbs that are unprocessed and all-natural. As you transition off keto, try introducing more lean proteins to your diet to keep your energy up and help your body adjust easier. The amount of protein you should consume daily varies greatly depending on your age, weight, and activity level.
Be Mindful of Sugar
Avoid consuming any sugar-heavy carbs until your body has had at least 2 weeks to adjust. Processed foods that are high in sugar often contain empty calories that won’t keep you full for long. Be aware of too much naturally occurring sugar, which can hide in things like honey and certain fruits. A good rule of thumb is to avoid anything with more than 4 grams of added sugar.

Stay Hydrated
Staying hydrated is another important factor when working on healthy habits post keto. Being dehydrated causes irritability and can make you feel hungry when you’re actually just thirsty.
Listen to Your Body
The amount of carbs that each person needs and can comfortably eat while transitioning off keto can vary greatly. Pay attention to how you feel after meals. Monitor your energy levels and any bloating or fatigue. If you experience constipation, increased appetite, energy crashes, or other unusual symptoms, ease up on your carb intake. Mild bloating or fatigue may last a little longer but will dissipate as your body adjusts.
Consider the Paleo or Mediterranean Diet
If you want to reintroduce carbs but you aren’t sure how to regulate your intake, try transitioning to either the paleo or Mediterranean diet. Both of these diets are similar to keto in requiring healthy fats and protein, but they also include carbs in moderation. Therefore, if you have trouble transitioning off keto without sticking to a strict diet, both of these options can help you. Transitioning from the keto diet to the Mediterranean diet offers a sustainable and nutritionally balanced diet approach to long-term health and weight loss, if desired.
Addressing Potential Side Effects
When you reintroduce carbs into your diet, it’s likely that you’ll experience some gastrointestinal issues, such as bloating. When you transition off keto and start reintroducing carbs into your diet, your body is naturally going to need time to adjust to the change.
Water-Weight Gain
Reintroducing carbs into the diet can lead to water-weight gain, in which the body stores glycogen in the muscles and liver. Glycogen retains water, and so transitioning from the keto diet to a Mediterranean diet can lead to an increase in water weight.

Gastrointestinal Issues
To help your body process carbs as you transition off the keto diet, plan to eat most of your carbs either right before or right after you workout. As you transition off the keto diet and reintroduce carbs, your body may be particularly susceptible to gastrointestinal issues, inflammation, blood sugar spikes, and changes in your insulin levels. To start, estimate the number of carbs you are eating in a day on keto and increase that by 25% every week until you hit the number of carbs you’d like to be eating on a regular basis.
10 Healthy Foods to Reintroduce After Keto
Here are 10 healthy foods to begin eating again on your keto maintenance plan:
- Strawberries: One cup of strawberry halves contains 11.7 g of carbs, along with 3 g of fiber and 89.4 milligrams of vitamin C.
- Carrots: One serving of baby carrots (about eight of them) contains 7 g of carbohydrates, while one raw carrot contains 5.75 g of carbs and 1.7 g of fiber.
- Black Bean Soup: A half-cup serving has 10 g of carbohydrates. Top with diced avocado for a boost of heart-healthy fat. Plain, cooked black beans are a great addition to a salad or tacos.
- Edamame: One cup of edamame has 13.8 g of carbohydrates. Edamame is also an excellent source of fiber, protein, and iron, and the legumes also contain vitamin C.
- Kiwi: One vitamin C-packed kiwi contains just 10.5 g of carbohydrates, making kiwi a perfect snack to nosh on post-keto.
- Butternut Squash: Half a cup of baked butternut squash - rich in eyesight-friendly vitamin A - supplies 11 g carbohydrates.
- Watermelon: One cup of watermelon has about 12 g of carbs and just 46 calories.
- Lentils: Top a salad with a quarter-cup of lentils for 58 calories, 4.5 g of protein, 10 g of carbs, and 4 g of fiber.
- Oatmeal: A half-cup serving of cooked oatmeal has 14 grams of carbs. Top with a dollop of nut butter or sliced nuts and blueberries.
- Sweet Potatoes: Half a medium sweet spud has just 57 calories, but 12 g of carbs. Some of the last things you should add back into your post-keto diet are carb-rich whole-grain bread, brown rice, and potatoes, including sweet potatoes, because it’s easy to pack in a lot of carbs at once with these foods.
Lifestyle Adjustments and Considerations
Weight loss isn’t just about the food - your environment, support system, and lifestyle all play a factor in it. So when keto is over and those things aren’t aligned correctly, it’s going to be easy to fall back into old habits and regain the weight.
Exercise
Regardless of whether you’re following a Keto diet or a Mediterranean diet, exercise remains beneficial. You may find your athletic performance boosts on a Mediterranean diet. Carbohydrate intake before a workout is essential. Complex carbohydrates help maintain blood sugar levels and prevent fatigue during intense or prolonged exercise. Incorporating post-meal walks into your daily routine (even just 2-15 minutes). Exercising regularly (preferably both aerobic and resistance training) to improve insulin sensitivity and cardiometabolic health.
Monitor Lipid Panels
If you have been following a high-fat diet such as the keto diet, it may be wise to check your lipid panels to ensure your cholesterol has not risen.
Avoid Overeating
When transitioning off of a limited diet like the low-carb limits of the keto diet, it may be tempting to overeat foods that were previously restricted. However, it’s important to increase the amount of carbs you eat gradually to avoid excess weight gain. Remember, the Mediterranean diet is about 45-55% calories from carbs.
Seek Professional Guidance
If you’re struggling to figure out how to transition off keto and reintroduce carbs in a healthy manner, meeting with a dietician may be a good option for you.
Key Takeaways: How to Add Carbs Back into Your Diet
When you want to add carbohydrates back into your diet after following keto, it’s important to allow your body to adjust over time. Remember that this is a slow transition (just like starting keto was!), so be patient and keep track of how you feel.
Strategies to Prevent Blood Sugar Spikes
- Eat fiber (vegetables) and proteins/fats first, and carbs last. (This slows the absorption of glucose into your bloodstream.)
- Drink a 10-ounce glass of water with a tablespoon of apple cider vinegar before or during your meal to reduce postprandial glucose spikes.
- Avoid eating carbs later in the evening, when your body is less sensitive to insulin.
