The ketogenic diet, or keto, is a low-carb, high-fat diet that causes weight loss and provides numerous health benefits. Some bodybuilders use keto as a gauge to determine the success of their diet. The diet involves drastically reducing carbohydrate intake and replacing it with fat. This reduction in carbs puts your body into a metabolic state called ketosis, where your body becomes efficient at burning fat for energy. While it's possible to build muscle on a keto diet, it can be challenging due to the body's initial reliance on carbs for fuel, and it may take longer. Some studies have also shown that a low-carb intake can hinder muscle building and protein synthesis. However, keto bodybuilding diet principles emphasize the importance of macronutrient breakdown, particularly ensuring sufficient protein intake to encourage the body to use stored body fat and protect muscle tissue.

What You'll Learn
Entering ketosis
A ketogenic diet is a low-carb, high-fat diet that offers many health benefits and causes weight loss. It involves drastically reducing carbohydrate intake and replacing it with fat. This reduction in carbs puts your body into a metabolic state called ketosis.
To enter ketosis, you should limit your carb consumption to 20 to 50 grams per day and fill up on healthy fats, such as meat, fish, eggs, nuts, and healthy oils. It's also important to moderate your protein consumption as it can be converted into glucose if consumed in high amounts, which may slow your transition into ketosis.
Intermittent fasting can also help you enter ketosis faster. The most common method involves limiting food intake to an 8-hour window and fasting for the remaining 16 hours.
There are several ways to know if you've entered ketosis, including blood, urine, and breath tests. The most definitive way is through a blood test, with blood levels of 0.5 to 3 mg/dl indicating nutritional ketosis. Other signs include increased thirst, dry mouth, frequent urination, decreased hunger or appetite, and flu-like symptoms, also known as the "keto flu."

Losing fat, not muscle
The ketogenic diet, or keto, is a low-carbohydrate, high-fat eating plan that has been used for centuries to treat specific medical conditions. When you cut carbs out of your diet, your body must find an alternative source of energy. Typically, the body turns to muscle tissue, breaking it down to fuel activity. However, if you consume an adequate amount of protein, this will help protect your muscle tissue and encourage your body to use stored body fat instead. This is called ketosis, a metabolic state where your body becomes very efficient at burning fat for energy.
To follow a ketogenic diet, you must limit your carb consumption to around 20 to 50 grams per day and fill up on fats, such as meat, fish, eggs, nuts, and healthy oils. It's also important to moderate your protein consumption as too much can prevent ketosis. Some people also practice intermittent fasting to enter ketosis faster, which involves limiting food intake to a certain time window and fasting for the remainder of the day.
The ketogenic diet is popular among bodybuilders and athletes as it is among the fastest fat-loss diets available. It allows them to perform high-intensity activities without "bonking" because their bodies have a ready supply of body fat, and they are no longer dependent on carbs for fuel. Additionally, studies have shown that a ketogenic diet can induce significant fat loss without affecting muscle performance or muscle mass.
However, there are some concerns about potential muscle loss on a keto diet, especially for those who lift weights or engage in resistance training. Some studies have found that keto diets may cause more muscle loss than other diet strategies, and the extreme carb restriction can make it harder to sustain progress. It is important to note that much of the initial weight loss on a keto diet is water weight, not fat, and long-term results may not show superior fat loss compared to other diets. Therefore, a gradual approach to reducing carbs may be a smarter strategy to support muscle protein synthesis and provide flexibility for continued fat loss.

Pros and cons
The ketogenic diet is a very low-carbohydrate, high-fat diet that encourages the body to burn fat for fuel instead of glucose. The diet is popular for weight loss and has been linked to various health benefits.
Pros
The ketogenic diet has several potential benefits for bodybuilders:
- The diet can help bodybuilders maintain lean muscle mass while in ketosis, even during times of high stress or a caloric deficit.
- It can be an effective way to shed fat and get lean, as the body burns fat for fuel instead of glucose.
- The diet may improve mental focus and control hunger, which can aid in weight loss and maintaining a caloric deficit.
- Bodybuilders can consume their regular amount of calories, which can help prevent hunger and ensure adequate fuel for intense workouts.
- Some endurance athletes have reported improved performance and endurance while following a ketogenic diet, which may also benefit bodybuilders.
- The ketogenic diet has been linked to various health benefits beyond weight loss, such as reducing seizures in children with epilepsy, controlling blood sugar levels, and potentially reducing the risk of certain chronic conditions.
Cons
However, there are also some potential drawbacks and challenges to consider:
- The ketogenic diet is very restrictive, eliminating or severely limiting many food groups, which can make it challenging to stick to and may lead to psychological distress and binge eating.
- The diet can cause dehydration due to the elimination of glycogen, which can stress the kidneys and potentially worsen underlying health conditions.
- It may lead to a drop in blood pressure due to changes in fluid balance.
- The ketogenic diet restricts carbohydrates, which are known to promote the release of insulin, an anabolic hormone that helps drive muscle growth. Therefore, it may be challenging to build muscle mass while following this diet.
- Timing carb intake and choosing the right types of carbs are crucial for maintaining energy levels during intense workouts.
- Building muscle on a ketogenic diet requires careful meal planning and consistent workouts, focusing on progressive overload and resistance training.

Macronutrient breakdown
The ketogenic diet is a low-carb, high-fat diet that causes weight loss and provides numerous health benefits. It involves drastically reducing carbohydrate intake and replacing it with fat. This reduction in carbs puts your body into a metabolic state called ketosis, where your body becomes very efficient at burning fat for energy.
The standard ketogenic macro ratio is 75% fat, 25% protein, and 5% carbs. However, for bodybuilders, the recommended macro ratio is slightly different, with a higher proportion of protein. Garrison, for instance, recommends a ratio of 65% fat, 30% protein, and 5% carbs for bodybuilders.
When first starting a keto diet, it is common to experience a transition phase where your body adjusts to using ketones as its primary fuel source. During this time, you may experience a decrease in energy and performance, as well as side effects like fatigue, dizziness, headaches, and nausea. This transition phase typically lasts anywhere from a few days to a week.
To build muscle on a keto diet, it is important to consume sufficient protein. A 2011 review of research found that the ideal amount of protein for bodybuilders was 0.82 grams per pound of body weight. It is also recommended to eat at a caloric surplus to build muscle.
There are some challenges and considerations to keep in mind when combining a keto diet with bodybuilding. One concern is the potential decrease in performance due to the lack of carbohydrates, which are a vital fuel source for muscles. Additionally, a keto diet can lead to poor muscle fullness and hydration since each gram of carbohydrate is assigned three grams of water. Furthermore, the high-fat content of a keto diet may not leave enough room for adequate protein intake, which is critical for muscle growth.
Overall, while it is possible to build muscle on a keto diet, it may take longer compared to other diets, and there are important considerations to keep in mind regarding performance, hydration, and nutrient intake.

High-protein keto
The ketogenic diet (keto) is a low-carb, high-fat diet that causes weight loss and provides numerous health benefits. When you cut carbs out of your diet, your body must find an alternative source of energy. The body turns first to muscle tissue, but if you take in an adequate amount of protein, this will help protect your muscle tissue and encourage your body to use stored body fat instead. This is why it is important to moderate your protein consumption when following a ketogenic diet.
High-protein, low-carb diets have become increasingly popular as a means of encouraging weight loss while maintaining or increasing muscle mass. This is because research shows that increasing protein intake while cutting calories can maintain muscle mass while promoting fat loss. High protein diets may help increase muscle mass when combined with resistance training.
However, there are some challenges to a high-protein keto diet. Firstly, it can be difficult to eat enough on keto because the low-carb, high-fat diet is so filling. Secondly, a very high-protein diet may throw you out of ketosis, as protein can be converted into glucose if consumed in high amounts. This may slow your transition into ketosis.
To ensure you are getting enough protein on a keto diet, you can include plenty of non-carb dairy and low-carb protein shakes throughout the day. It is also important to be consistent with nutrition and not just on training days. This means basing your macronutrient intake on your goals and eating the same macros every day, whether it is a rest day or a training day.
Some keto bodybuilders recommend up to 2.2 grams of protein per kilogram of body weight. To reach this protein goal, you can also add additional fat to get your calories up.
