Strength Training And Keto: Weight Gain Or Loss?

The ketogenic diet is a high-fat, low-carb diet that is often used for weight loss. It involves drastically lowering your carb intake and consuming fat instead, which helps your body transition into a metabolic state known as ketosis.

There is a common misconception that it is impossible to build muscle on a keto diet. However, studies have shown that it is possible to build muscle and improve strength on the keto diet, much like on a traditional higher-carb diet.

To build muscle on a keto diet, it is important to determine your calorie intake, eat plenty of protein, track your carb intake, and increase your fat intake. It is also crucial to incorporate resistance training and consider taking supplements if needed.

Additionally, it is worth noting that starting strength training on a keto diet may initially cause a drop in strength and performance as your body adapts to relying on ketones.

Keto diets can help build muscle, but may impair hypertrophy

The ketogenic diet is a popular, low-carb, high-fat diet that can help with weight loss, improving lipid markers for cardiovascular health, and reversing diabetes. It is also a viable option for building muscle, although it may not be optimal due to the reduced intake of carbohydrates, which are essential for muscle growth.

Building Muscle on Keto

Building muscle on a keto diet is possible, but it can be challenging. The key to building muscle on keto is to ensure adequate protein intake and a caloric surplus, along with regular resistance training. Protein is made up of amino acids, which are the "building blocks" of proteins and are essential for muscle growth and maintenance. The branched-chain amino acids (BCAAs) leucine, isoleucine, and valine are particularly important for muscle building. Leucine is the most potent driver of protein synthesis and can be found in meat, whey, and eggs.

A typical keto diet consists of 70% fat, 25% protein, and only 5% carbohydrates. This means that protein intake may be lower than what is optimal for muscle growth. However, some sources suggest that a keto diet can include a moderate amount of protein, and it is still possible to get a significant amount of protein while staying within the keto guidelines. For example, a 2,500-calorie diet with 15% of calories from protein would provide 93 grams of protein. Additionally, some people may be able to include more protein in their keto diet without being kicked out of ketosis.

The Role of Carbohydrates in Muscle Building

Carbohydrates are an essential ingredient for muscle growth as they increase insulin and IGF-1, which stimulate muscle protein synthesis. However, studies have shown that protein ingestion alone after resistance exercise is just as effective as a combination of protein and carbohydrates in increasing muscle protein synthesis. This suggests that carbohydrates may not be necessary for muscle growth, as long as protein intake is sufficient.

The Impact of Keto on Hypertrophy

While it is possible to build muscle on a keto diet, there may be some impairments to hypertrophy due to the reduced carbohydrate intake. Insulin is an anabolic hormone that is released in response to carbohydrate intake, and it plays a crucial role in muscle growth. By limiting carbohydrate intake, keto diets may reduce insulin levels and potentially impair muscle growth. Additionally, the body's preferred energy source during high-intensity exercise is glucose, which comes from carbohydrates. If you are in ketosis, your body may not be able to use stored carbohydrates effectively during high-intensity exercise, which could impact your performance.

In conclusion, keto diets can help build muscle, but they may not be the optimal choice due to the reduced carbohydrate intake, which plays an important role in muscle growth and performance during high-intensity exercise. While it is possible to build muscle on keto, there may be some impairments to hypertrophy, especially for strength athletes who require high-volume training. However, keto diets can still be beneficial for building muscle, especially for those looking to lose body fat and improve body composition.

Protein is key to muscle growth, but too much may stop ketosis

Protein: Key to Muscle Growth, but Too Much May Stop Ketosis

Protein is essential for muscle growth and repair, but opinions vary on whether too much can kick you out of ketosis.

The Role of Protein in Keto

Protein is a building block of life and a necessary component of any diet. It is crucial for healthy brain function, skin, bone, and muscle health, and building muscle mass. It also helps with workout recovery and can prevent hair loss.

The short answer is: it depends. Some people find that higher amounts of protein interfere with their ability to maintain ketosis, while others can tolerate more without problems.

Protein can be used by the body to produce glucose during low-carbohydrate intake through a process called gluconeogenesis. This happens continuously, as certain tissues in the body rely exclusively on glucose, such as red blood cells, the renal medulla, and testes.

However, too much protein may decrease ketone levels since protein has a moderate insulin-stimulating effect, and insulin increases can inhibit ketone production. Research also suggests that the amino acid alanine may suppress ketone production.

The general guideline is to stay within the recommended protein range (30% of your daily calories if following a standard keto diet) or between 0.73 and 1 gram of protein per pound of body weight.

Those who are older, recovering from an injury or illness, athletes, or living an active lifestyle may need more protein. Diabetics or prediabetics may benefit from slightly lower protein levels.

Healthy Sources of Protein on Keto

There are plenty of healthy sources of protein to choose from on a keto diet, including leaner and fattier options:

• Full-fat dairy
• Meat: beef, poultry, pork
• Fish: mackerel, tuna, salmon, trout, halibut, cod, catfish, mahi-mahi
• Shellfish: oysters, clams, crab, mussels, lobster
• Organ meats: heart, liver, tongue, kidney, offal
• Eggs
• Vegetarian sources: macadamia nuts, almonds, nut butter
• Collagen protein supplement

In Summary

While protein is key to muscle growth and has numerous health benefits, it is possible to have too much, which may decrease ketone levels and inhibit ketosis. The amount of protein needed varies from person to person, and it is important to find your ideal level through testing and experimentation.

Carbs are not essential for muscle growth

Starting strength training while on a keto diet will not necessarily cause weight gain. In fact, the keto diet is a weight-loss diet. However, it is also possible to build muscle while on a keto diet.

The idea that carbohydrates are necessary for muscle growth likely comes from the fact that insulin and IGF-1, which both rise in response to carbohydrate intake, also stimulate muscle protein synthesis. Insulin is highly anabolic, and it stimulates muscle protein synthesis. However, this does not mean that carbohydrates are essential for muscle growth.

When studies compare protein ingestion alone to a combination of protein and carbs after resistance exercise, there is no difference in muscle protein synthesis. This is probably because the amount of protein ingested is enough to raise insulin levels and activate mTOR, a cellular sensor that can sense whether the body is in a "fed" or "fasted" state. More insulin does not necessarily mean more protein synthesis in this case.

Beta-hydroxybutyrate (BHB), the main energy ketone, interacts with leucine to promote muscle protein synthesis and prevent muscle breakdown. Leucine is a branched-chain amino acid (BCAA) that is one of the most important amino acids for muscle building. It is found in meat, whey, and eggs.

Additionally, low-carb diets are generally higher in protein than high-carb diets, and the keto diet may increase adrenaline, which inhibits muscle breakdown.

Keto and Muscle Growth

Research has shown that athletes who adopt a keto diet experience greater body fat loss than a group of high-carb dieters. After eight weeks of a keto diet and resistance training program, young men experienced reductions in fat mass and visceral adipose tissue—changes that weren't seen in the non-keto groups.

The keto diet has also been shown to preserve muscle mass during training. In one study, a group of elite gymnasts adopted a ketogenic diet while maintaining their training routines. By the end of the study, muscle mass was the same, but they got leaner, reducing body fat and body fat percentage significantly.

Another study provided similar evidence. After six weeks on a ketogenic diet, athletes in a CrossFit program experienced no significant change in muscle mass but significantly reduced their weight, percent body fat, and fat mass.

While carbs may be beneficial for muscle growth, they are not essential. A protein-sufficient keto diet is perfectly compatible with strength gains.

Keto may be optimal for fat loss, not muscle gain

The ketogenic diet is a very low-carb, high-fat diet that is often used for weight loss. While it can be effective for fat loss, there is some debate about its effects on muscle gain.

The Science Behind Keto and Muscle Gain

The keto diet involves drastically lowering carbohydrate intake and using fat as an alternative fuel source. This metabolic state is known as ketosis, where the body uses ketones for energy instead of glucose from carbohydrates.

When it comes to building muscle, the keto diet may not be the optimal choice. Insulin is an anabolic hormone that helps create conditions for muscle growth. However, the keto diet restricts carbohydrates, which are known to promote the release of insulin.

Research on Keto and Muscle Gain

A study published in the Journal of the International Society of Sports Nutrition examined the effects of an 8-week ketogenic diet on resistance-trained men. The results showed that the keto group lost more fat, but they did not have a significant increase in muscle mass compared to the non-keto group.

Another study compared a low-carb diet to a traditional Western diet during a 10-week resistance training program. The low-carb group experienced similar lean body mass gains as the group eating a normal diet. However, the keto diet led to a greater increase in testosterone, which is important for muscle growth.

Factors to Consider

While the keto diet may not be optimal for muscle gain, there are other factors to consider. The amount of protein consumed is crucial for building muscle, and the keto diet may not provide enough protein to support muscle growth. Additionally, the keto diet can be challenging to stick to, and it may not be suitable for everyone.

In conclusion, while the keto diet may be effective for fat loss, it may not be the best choice for those looking to gain muscle mass. More research is needed to fully understand the effects of the keto diet on muscle gain, and it's important to consult with a healthcare professional or certified trainer before starting any new diet or exercise program.

Keto can be combined with resistance training

The ketogenic, or keto, diet is a very low-carb, high-fat diet. It involves drastically lowering your carb intake and consuming fat instead. This helps your body transition into a metabolic state known as ketosis.

Ketosis occurs when your body has limited access to glucose or carbs, the body's preferred source of fuel for many processes. To compensate, your body uses fat to make ketone bodies as an alternative fuel source.

Keto is a weight-loss diet, but it doesn't have to be. It can also be used to build muscle. However, there is a common myth that the keto diet makes it hard, if not impossible, to gain muscle.

Building muscle on keto

It is possible to build muscle on the keto diet. For example, a study in 25 college-aged men found that a traditional Western diet and the ketogenic diet were equally effective for muscle gain, strength, and performance.

Other studies have shown that keto may provide similar strength and performance gains as a conventional high-carb diet while also helping shed body fat.

If you're new to keto, you may initially experience a drop in strength and performance. This is temporary and happens because your body is adapting to relying on ketones.

How to build muscle on a keto diet

• Determine your calorie intake: To build muscle, you need to consistently eat more calories than you burn. The number of calories you need to eat per day depends on several factors, such as your weight, height, lifestyle, sex, and activity levels.
• Eat plenty of protein: Protein is the building block of muscles, so you need to consume more protein than your body breaks down. Most studies suggest that eating 0.7–0.9 grams of protein per pound of body weight (1.6–2.0 grams per kg) is ideal for building muscle.
• Track your carb intake: To reach and stay in ketosis, most people need to eat fewer than 50 grams of carbs per day, although the exact value can vary. You may find that timing your carb intake around your workouts can be beneficial, especially if you believe your performance is affected.
• Increase your fat intake: After accounting for protein and carbs, fat should make up the rest of your diet. Both protein and carbs provide 4 calories per gram, while fat provides 9.
• Resistance train regularly: Resistance training typically involves lifting weights or doing other strength-based exercises to build strength and gain muscle mass. According to a review of 10 studies, resistance training at least twice a week was more effective at promoting muscle growth than training once per week.
• If necessary, consider supplements: While not required, supplements may help you build muscle. For example, you could use a protein powder supplement, such as whey, casein, pea, or hemp protein. You could also try using a creatine monohydrate supplement, as studies show that it can aid gym performance, leading to more muscle gain.
