The ketogenic diet, commonly known as the keto diet, is a low-carb, high-fat eating plan that has become popular for its effectiveness in weight loss. However, what if your goal is the opposite—gaining weight? Whether you’re looking to build muscle, recover from an illness, or simply add a few pounds, gaining weight on a keto diet is entirely possible. This guide will walk you through the steps to do so, including how to calculate your calorie needs, choose the right foods, and incorporate exercise into your routine.
1. Understanding the Basics of a Keto Diet
Before diving into weight gain strategies, it’s important to understand the fundamentals of the keto diet.
- What is Keto?
The keto diet is designed to put your body into a state of ketosis, where it burns fat for fuel instead of carbohydrates. To achieve this, your daily intake should consist of approximately 70-80% fat, 20-25% protein, and 5-10% carbohydrates. - Ketosis and Weight Gain
Typically, ketosis is associated with weight loss, but by increasing your calorie intake while maintaining the macronutrient ratios, you can shift the focus to weight gain. The key is to consume more calories than your body burns while staying in ketosis.
2. Calculate Your Calorie Needs
The first step to gaining weight on a keto diet is to determine how many calories you need to consume daily. This involves calculating your Total Daily Energy Expenditure (TDEE).
- Calculate Your Basal Metabolic Rate (BMR)
Your BMR is the number of calories your body needs to maintain basic physiological functions, like breathing and digestion, while at rest. You can calculate your BMR using the Harris-Benedict equation:
- Determine Your Activity Level
Multiply your BMR by an activity factor to find your TDEE: - Sedentary (little or no exercise): BMR × 1.2
- Lightly active (light exercise/sports 1-3 days/week): BMR × 1.375
- Moderately active (moderate exercise/sports 3-5 days/week): BMR × 1.55
- Very active (hard exercise/sports 6-7 days a week): BMR × 1.725
- Super active (very hard exercise & a physical job): BMR × 1.9
- Add Calories for Weight Gain
To gain weight, you need to consume more calories than your TDEE. A safe and sustainable approach is to aim for a surplus of 250-500 calories per day. This surplus should help you gain 0.5-1 pound (0.2-0.5 kg) per week.
3. Choosing the Right Keto Foods for Weight Gain
Not all keto foods are created equal, especially when your goal is weight gain. You need to focus on calorie-dense, nutrient-rich foods that align with your macronutrient goals.
- High-Fat Foods
Since fat is the primary macronutrient in the keto diet, choose foods that are high in healthy fats: - Avocados: Rich in monounsaturated fats, fiber, and potassium. One medium avocado has around 250 calories.
- Nuts and Seeds: Almonds, macadamia nuts, chia seeds, and flaxseeds are excellent sources of fat and calories. For example, 1 ounce of macadamia nuts provides about 200 calories.
- Nut Butters: Peanut butter, almond butter, and other nut butters are calorie-dense and easy to add to smoothies or snacks. Two tablespoons of almond butter have about 200 calories.
- Coconut Oil and MCT Oil: These oils are easily absorbed and converted into ketones, making them ideal for a keto diet. One tablespoon of coconut oil has 120 calories.
- Cheese: High in fat and calories, cheese can be a versatile addition to meals. One ounce of cheddar cheese provides around 110 calories.
- Protein Sources
Protein is crucial for muscle growth and repair, but be careful not to consume too much, as excess protein can be converted into glucose, potentially kicking you out of ketosis: - Fatty Cuts of Meat: Ribeye steak, pork belly, and lamb chops are rich in both protein and fat.
- Fatty Fish: Salmon, mackerel, and sardines are excellent sources of omega-3 fatty acids and protein.
- Eggs: A versatile and nutritious option, with one large egg containing about 70 calories.
- Low-Carb Vegetables
While vegetables are lower in calories, they are essential for their vitamins, minerals, and fiber: - Leafy Greens: Spinach, kale, and arugula are low in carbs but packed with nutrients.
- Cruciferous Vegetables: Broccoli, cauliflower, and Brussels sprouts are low-carb and fiber-rich.
4. Meal Planning for Weight Gain on Keto
Creating a meal plan can help you stay on track and ensure you’re consuming enough calories and nutrients.
- Sample Meal Plan Breakfast:
- Scrambled eggs cooked in butter with avocado slices.
- Keto coffee (coffee blended with butter or MCT oil). Lunch:
- Ribeye steak with a side of sautéed spinach in olive oil.
- A handful of macadamia nuts. Snack:
- Greek yogurt with a tablespoon of almond butter. Dinner:
- Baked salmon with a side of roasted Brussels sprouts and a generous drizzle of olive oil.
- A small mixed greens salad with avocado and a high-fat dressing. Dessert:
- A keto-friendly chocolate mousse made with heavy cream and dark chocolate.
- Incorporate Snacks
To increase your calorie intake, include snacks between meals. Nut butters, cheese, and keto fat bombs are excellent options that are both satisfying and calorie-dense. - Drink Calorie-Rich Beverages
Consider adding calorie-dense drinks like keto smoothies (with avocado, coconut milk, and protein powder) or fat-rich coffee to your daily routine.
5. Exercise for Muscle Gain on a Keto Diet
Exercise is a critical component of any weight gain plan, especially if you’re looking to build muscle.
- Strength Training
Focus on compound exercises like squats, deadlifts, bench presses, and pull-ups. These exercises engage multiple muscle groups, making them effective for muscle growth. - Rest and Recovery
Allow your muscles time to recover by ensuring adequate rest between workout sessions. This will help prevent injury and promote muscle growth. - Track Your Progress
Keep a log of your workouts and progress. Track your weight, body measurements, and strength gains over time.
6. Monitor Your Macronutrients and Ketosis
To gain weight successfully on a keto diet, it’s crucial to monitor your macronutrient intake and ensure you remain in ketosis.
- Use a Food Diary or App
Track your daily food intake using a food diary or app like MyFitnessPal or Carb Manager. This will help you stay within your macronutrient goals and ensure you’re consuming enough calories. - Test Your Ketone Levels
Regularly test your ketone levels using urine strips, a blood ketone meter, or a breathalyzer. This will help you confirm that you’re in ketosis, which is essential for reaping the benefits of a keto diet.
7. Address Common Challenges
Gaining weight on a keto diet can come with its own set of challenges. Here are some common obstacles and tips for overcoming them:
- Difficulty Eating Enough Calories
If you’re struggling to eat enough, try increasing the frequency of your meals or adding calorie-rich snacks. Drinking calorie-dense beverages like keto smoothies can also help. - Appetite Suppression
Ketosis can sometimes suppress appetite, making it challenging to consume more calories. Focus on eating more calorie-dense foods and consider reducing intermittent fasting if it’s part of your routine. - Digestive Issues
Some people experience digestive issues on a high-fat diet. Incorporate plenty of fiber from low-carb vegetables and consider taking a digestive enzyme supplement if needed.
8. Supplements to Support Weight Gain
Supplements can be a helpful addition to your weight gain plan, especially if you’re struggling to meet your calorie or nutrient needs through food alone.
- Protein Powder
A high-quality protein powder can help you increase your protein intake without overloading on carbohydrates. Opt for keto-friendly options like whey isolate or collagen protein. - MCT Oil
Medium-chain triglyceride (MCT) oil is easily absorbed and converted into ketones, providing a quick energy source. Adding it to your coffee, smoothies, or salads can increase your calorie intake.
- Creatine
Creatine is a well-researched supplement that can help increase muscle mass and strength, especially when combined with resistance training. It works by supplying your muscles with additional energy, allowing you to perform more reps and lift heavier weights during workouts. A typical dose is 5 grams per day, but it’s essential to stay hydrated when taking creatine, as it can cause water retention in muscles. - Exogenous Ketones
Exogenous ketones are supplements that can help boost your ketone levels, providing additional energy and potentially helping you stay in ketosis even if you consume a few more carbs than usual. While they aren’t necessary for everyone, they can be beneficial if you’re struggling to maintain ketosis. - Fiber Supplements
If you find it challenging to get enough fiber from vegetables alone, consider adding a fiber supplement like psyllium husk or a keto-friendly fiber powder. These can help with digestion and prevent constipation, which can sometimes be an issue on a high-fat diet.

10. Track Your Progress and Adjust as Needed
Gaining weight on a keto diet is a gradual process that requires consistency and patience. Tracking your progress allows you to make necessary adjustments to your diet and exercise routine.
- Weigh Yourself Regularly
Aim to weigh yourself once a week at the same time of day and under the same conditions. This will help you monitor your progress without getting too focused on day-to-day fluctuations. - Take Body Measurements
In addition to tracking your weight, measure your waist, hips, chest, arms, and legs. Muscle gain can sometimes cause your weight to stay the same or even decrease as fat is replaced by lean muscle, so measurements provide another way to assess progress. - Adjust Your Calorie Intake
If you find that you’re not gaining weight after a couple of weeks, consider increasing your daily calorie intake by another 100-200 calories. Conversely, if you’re gaining weight too quickly (more than 1 pound per week), you might need to reduce your intake slightly to prevent excessive fat gain. - Evaluate Your Macronutrient Ratios
If you’re struggling to stay in ketosis, you may need to adjust your macronutrient ratios. You can lower your protein intake slightly or increase your fat intake to ensure your body remains in ketosis while still supporting weight gain.
11. Common Mistakes to Avoid
When trying to gain weight on a keto diet, it’s easy to make mistakes that can hinder your progress. Here are some common pitfalls and how to avoid them:
- Overeating Carbohydrates
Eating too many carbs can knock you out of ketosis, making it harder to gain weight in a healthy way. Stick to low-carb vegetables and be mindful of hidden carbs in processed foods. - Neglecting Protein Intake
While keto is a high-fat diet, protein is still essential for muscle repair and growth. Make sure you’re consuming enough protein to support your activity level, but not so much that it affects your ketosis. - Ignoring Fiber
A diet high in fat can lead to digestive issues if fiber is neglected. Ensure you’re getting enough fiber from low-carb vegetables, nuts, and seeds, or consider adding a fiber supplement. - Not Drinking Enough Water
Staying hydrated is crucial, especially if you’re taking supplements like creatine. Drink plenty of water throughout the day to support your metabolism and overall health.
