The ketogenic diet has become increasingly popular for weight loss, but can it be used to bulk up? The keto diet is a very low-carb, high-fat diet that encourages the body to use ketones as fuel instead of glucose. While it may be possible to build muscle on a keto diet, it is challenging due to the restricted intake of carbohydrates, which promote the release of insulin, an anabolic hormone that helps create conditions that drive muscle growth. Studies have shown that a conventional bodybuilding diet is better for building muscle and avoiding fat gain than a cyclical ketogenic diet. However, some people have found success in bulking on a keto diet by focusing on consuming enough protein and calories, and by allowing for an adaptation period for the body to adjust to using fat and ketones as fuel.

What You'll Learn
Consume fewer than 50 grams of carbs per day
To bulk on a ketogenic diet, it is important to consume fewer than 50 grams of carbohydrates per day. This is a crucial step in transitioning your body into a state of ketosis, where it burns fat instead of carbohydrates for energy. Ketosis is the metabolic state in which your body uses ketones, produced from stored fat, as its primary fuel source.
By limiting your carbohydrate intake to less than 50 grams per day, you encourage your body to become fat-adapted, efficiently burning fat for energy. This is a fundamental principle of the keto diet, which involves getting 70-80% of your daily calories from fat. However, it is important to note that the exact ratio of macronutrients in a ketogenic diet may vary and is not standardized.
To ensure you stay within the 50-gram carbohydrate limit, it is advisable to choose low-carb foods wisely. For example, 1,000 grams of broccoli, raspberries, or Brazil nuts contain approximately 50 grams of net carbs. On the other hand, high-carb foods like cashews and lentils can quickly exceed this limit, with 200 grams of cashews or 100 grams of lentils containing about 50 grams of net carbs.
While the keto diet emphasizes fat intake, it is important to consume a moderate amount of protein. Excess protein can prevent ketosis, as amino acids in protein can be converted to glucose. The recommended daily protein intake on a keto diet is slightly higher for people assigned male at birth (56 grams) than for those assigned female at birth (46 grams).
Sticking to fewer than 50 grams of carbohydrates per day on a keto diet may require careful planning and monitoring of your food choices. It is important to note that net carbs, which are calculated by subtracting fiber and considering sugar alcohol content, are the focus of this limit. This calculation can vary depending on the specific foods consumed.

Focus on high-fat foods
The ketogenic diet is a low-carbohydrate, high-fat diet. Typically, 70% to 80% of calories come from fats, with only a moderate intake of protein making up 10-20% and a maximum of 10% from carbohydrates. This means eating foods such as meat, fish, eggs, nuts, oils, and some low-carb vegetables and greens.
To bulk on a ketogenic diet, it is important to focus on eating a surplus of calories, which can be achieved by eating more high-fat foods. Prioritise healthy fats like monounsaturated and polyunsaturated fats found in olive oil, avocado, fatty fish, nuts, cheese, and butter. These foods will help you to reach your calorie goals while remaining in ketosis.
It is important to note that the ketogenic diet is challenging to maintain and can lead to nutrient deficiencies if not carefully planned. Some people experience negative side effects known as "the keto flu", which can include constipation, headaches, fatigue, low mood, and irritability. Therefore, it is important to include a variety of allowed meats, fish, vegetables, fruits, nuts, and seeds to ensure adequate intake of fibre, vitamins, and minerals.
Additionally, the ketogenic diet is not suitable for everyone. It is not recommended for those who are training, as carbohydrates are needed for energy during workouts. Furthermore, the high-fat nature of the diet could have negative impacts on heart health. It is always best to consult a medical professional before starting any new diet.

Ensure adequate protein intake
While the ketogenic diet is typically associated with weight loss, some people may want to bulk up while still adhering to its principles. However, this can be challenging as the keto diet restricts carbohydrates, which promote the release of insulin, an anabolic hormone that helps create conditions for muscle growth.
To bulk on a ketogenic diet, it is crucial to ensure adequate protein intake. Protein is essential for muscle growth and repair, and keto diets tend to be moderate in protein content. Here are some detailed tips to ensure sufficient protein consumption:
First, it is important to understand the macronutrient composition of the ketogenic diet. Typically, keto involves getting about 60%-75% of calories from fat, 20%-30% from protein, and only 5%-10% from carbohydrates. This means that in a 2000-calorie diet, an individual would aim for 1000-1500 calories from fat, 400-600 calories from protein, and 100-200 calories from carbohydrates.
Second, choose protein-rich foods that align with the keto diet. Animal-based proteins such as meat, poultry, fish, eggs, and dairy products are excellent sources of complete proteins. Additionally, certain plant-based sources like nuts, seeds, and soy products can contribute to protein intake while still adhering to keto principles.
Third, consider the timing of protein intake. Spread protein intake throughout the day, aiming for a protein source at each meal and snack. This helps ensure a consistent supply of amino acids, the building blocks of protein, to support muscle growth and repair. Aim for a serving of protein within an hour of working out, as this is when muscles are particularly receptive to rebuilding and growth.
Fourth, be mindful of protein quality. Not all proteins are created equal. Choose high-quality, complete protein sources that provide all the essential amino acids your body needs. Animal-based proteins tend to be complete proteins, while plant-based proteins may need to be combined to ensure a complete amino acid profile.
Finally, consider supplementing with protein powders or mass gainers. If it is challenging to meet protein requirements through whole foods alone, protein supplements can help bridge the gap. Whey, casein, and soy protein powders are popular options that can be added to shakes, smoothies, or even baked goods to boost protein content. Mass gainers are high-calorie supplements that often combine protein, carbohydrates, and other nutrients to support weight gain and muscle growth.

Adapt to using fat and ketones for energy
The ketogenic diet is a low-carbohydrate, high-fat diet that causes a metabolic shift in the body, encouraging it to use fat and ketones for energy instead of glucose, which is the body's preferred source of energy. This metabolic state is called ketosis.
To enter ketosis, you need to consume fewer than 50 grams of carbohydrates per day, with some sources suggesting as low as 20 grams, and get the rest of your calories from high-fat foods. This typically means that 70-80% of your calories come from fat, with the remaining 20-30% from protein and carbohydrates.
When adapting to using fat and ketones for energy, it is important to understand the role of ketones in the body. Ketones, or ketone bodies, are produced from stored fat when the body is deprived of glucose. They can be used as an energy source by vital organs such as the heart, muscle tissue, kidneys, and the brain. In fact, ketone bodies produce a greater amount of ATP (adenosine triphosphate), which is often referred to as a "super fuel," when compared to glucose.
Additionally, ketone bodies can have other benefits such as reducing free radical damage and enhancing the body's antioxidant capacity. They also play a direct hunger-reducing role, which can lead to decreased food cravings and a reduced desire to eat.
However, it is important to note that adapting to a ketogenic diet may come with some challenges. Some people may experience a temporary drop in strength and performance as their bodies adjust to using ketones for energy. This is because the body's preferred source of energy is glucose, and it takes time for the body to become efficient at using ketones as an alternative fuel source. Furthermore, it is important to moderate protein consumption, as high amounts can be converted into glucose, slowing the transition into ketosis.
To support the transition and adapt to using fat and ketones for energy, there are several strategies that can be employed:
- Practicing intermittent fasting, such as limiting food intake to an 8-hour window and fasting for the remaining 16 hours, can help enter ketosis faster.
- Certain supplements can be beneficial, such as exogenous ketones, MCT oil (added to drinks or yogurt), and minerals like added salt.
- Caffeine can provide benefits for energy, fat loss, and performance.
- Creatine can be beneficial for health and performance, especially when combining a ketogenic diet with exercise.
- Whey protein in shakes or yogurt can help increase daily protein intake.

Be mindful of potential side effects
While bulking on a ketogenic diet, it is important to be mindful of potential side effects. Here are some considerations to keep in mind:
Firstly, a ketogenic diet involves drastically lowering your carbohydrate intake and consuming more fats instead. This dietary shift can lead to a temporary drop in strength and performance as your body adapts to using ketones as its primary fuel source. This transition phase may cause a slight decrease in your training capacity, but it is often temporary and can be managed by ensuring adequate calorie intake and nutrient density in your diet.
Secondly, the ketogenic diet can affect the way your body processes electrolytes. As your carbohydrate intake decreases, there is a tendency for more electrolytes to be secreted from the body in urine, leading to a potential electrolyte imbalance. Electrolytes are crucial for successful muscle building, so it's important to actively replenish them. Include electrolyte-rich foods in your diet, such as those containing sodium, potassium, calcium, and magnesium. While supplements can provide additional support, they should not be your primary source of electrolytes.
Additionally, the ketogenic diet may not be suitable for everyone. Some individuals may experience challenges with adherence beyond eight weeks due to factors like satiety and dietary restrictions. It is important to monitor how your body responds and make adjustments as needed. Furthermore, the ketogenic diet may not align with specific training programs or sports that heavily rely on carbohydrates for fuel. In such cases, a targeted ketogenic approach or a different nutritional strategy may be more appropriate.
It is worth noting that the ketogenic diet has been associated with various health benefits beyond weight loss, including aiding in the management of epilepsy, controlling blood sugar levels, and potentially reducing the risk of certain chronic conditions. However, as with any dietary change, it is always advisable to consult with a healthcare professional or a dietician to ensure that it is safe and suitable for your individual needs and health status.
Lastly, while bulking, it is important to ensure adequate protein intake to support muscle growth and repair. The ketogenic diet encourages keeping protein intake moderate to prevent triggering gluconeogenesis, where protein is used as a fuel source instead of body fat. However, insufficient protein can hinder muscle growth. Thus, it is crucial to strike a balance by consuming enough protein to support muscle development while adhering to the principles of the ketogenic diet.
