Keto And Weight Training: A Powerful Combination?

The ketogenic diet is a high-fat, low-carb diet that puts the body in a state of ketosis, where it burns fat instead of carbohydrates for energy. While it can be an effective way to lose weight, it may not be the best diet for those looking to build muscle through weight training.

When it comes to weight training, the body typically relies on carbohydrates for energy. On a keto diet, the body doesn't have the same access to carbohydrates, which can lead to decreased performance during high-intensity workouts. However, some people have found success in building strength and muscle on a keto diet, as long as they are consuming enough protein and calories.

Overall, while it is possible to combine keto and weight training, it may not be the most effective approach for those looking to build muscle mass and improve athletic performance.

Keto may be better for maintaining muscle mass than building it

The ketogenic diet has become increasingly popular for weight loss, but can it help build muscle mass? The short answer is yes, but it may be better for maintaining muscle mass than building it.

The keto diet is a very low-carb, high-fat diet that puts your body into a metabolic state called ketosis. In this state, your body uses fat as its primary energy source instead of glucose from carbohydrates. This can lead to weight loss and other potential health benefits.

Building Muscle on Keto

Building muscle on a keto diet is possible, but it may be more challenging than on a traditional high-carb diet. This is because carbohydrates are an essential ingredient for muscle growth, and on keto, only about 5% of your calories come from carbs.

However, it's important to note that protein, which is crucial for muscle building, still plays a significant role in the keto diet, comprising around 20% of your calories. By consuming adequate amounts of protein and incorporating strength training, it is possible to build and maintain muscle mass while on keto.

Maintaining Muscle Mass on Keto

The keto diet may be particularly effective for maintaining muscle mass while losing fat. This is because keto can help preserve muscle mass by utilizing protein more efficiently and promoting fat oxidation. Additionally, the appetite-suppressing effects of ketosis can aid in weight loss without sacrificing muscle mass.

However, it's important to note that long-term studies on the effects of keto on muscle mass are lacking, and there is some evidence that keto may impair resistance training-induced muscle hypertrophy. Therefore, while keto may be beneficial for maintaining muscle mass, more research is needed to determine its effectiveness in building muscle compared to traditional high-carb diets.

High-intensity exercise is more challenging on keto

The ketogenic diet is a high-fat, low-carb approach to eating that has become increasingly popular in recent years. While it can be an effective way to lose weight, there is some evidence to suggest that it may not be the best diet for those engaging in high-intensity exercise.

The Ketogenic Diet and Exercise Performance

The keto diet aims to keep the body in a state of ketosis, where it burns fat for energy instead of carbohydrates, which are the body's preferred energy source. This shift in metabolism may be beneficial for weight loss, but it can also impact exercise performance, especially during high-intensity workouts.

During high-intensity exercise, the body relies on carbohydrates for fuel. When carbohydrates are restricted, as in the case of a keto diet, the body may struggle to maintain the same level of performance. This is particularly true for exercises that require high-rep activity or prolonged periods of activity.

The Impact of Keto on High-Intensity Exercise

Studies have shown that a ketogenic diet can reduce athletes' anaerobic performance. Specifically, exercises that rely on the glycolytic energy system, which runs on glucose from carbohydrates, may be compromised when on a keto diet. This includes high-intensity exercises such as CrossFit, strongman, and bodybuilding.

Additionally, the keto diet may impair muscle hypertrophy and decrease muscle performance, especially when expressed in absolute values (e.g., total weight lifted) rather than relative to body mass. This means that while an individual may be losing weight on a keto diet, their strength and power output may also decrease, impacting their overall exercise performance.

Strategies for Combining Keto and High-Intensity Exercise

For those who want to combine a keto diet with high-intensity exercise, there are a few strategies that may help:

• Modify your keto diet: Even if you're on a low-carb keto diet, you can tweak your diet to include a bit more carbs to give you the energy boost needed for high-intensity workouts. This can be done without impacting your keto progress.
• Allow time for adjustment: Your performance may suffer initially when starting a keto diet, but it may improve once your body adjusts to using fat as its primary fuel source.
• Focus on moderate-intensity workouts: Instead of high-intensity exercises, opt for moderate-intensity workouts that are less reliant on carbohydrates for fuel. This can help you stay active while still adhering to a keto diet.
• Consider a cyclical or targeted keto diet: If you lead a very active life, you may benefit from a cyclical keto diet (CKD) or a targeted keto diet (TKD), which involve strategic carb intake to provide the energy needed for high-intensity exercise.

A keto diet may increase testosterone

The ketogenic diet is a high-fat, low-carb, and moderate-protein diet. It forces the body to use fat as fuel by starving it of carbohydrates. The body then produces and uses ketone bodies as fuel instead of glucose. This is purported to be a cleaner and more efficient fuel, promoting metabolic flexibility within the body.

The keto diet has been shown to increase testosterone levels in some individuals. One theory for this is the increase in cholesterol intake. Testosterone is based on the cholesterol molecule, so a high-fat diet can lead to higher cholesterol and, in turn, higher testosterone production.

Another theory is that the keto diet improves health and reduces body fat, which can lead to increased testosterone levels. This is especially true for overweight individuals, where calorie restriction and fat loss can improve testosterone levels.

However, it is important to note that extreme dieting and very low-fat intakes can suppress hormone production, including testosterone. Therefore, a balanced approach is recommended, such as eating plenty of vegetables and limiting saturated fat.

Additionally, keto may not be suitable for everyone and can be very restrictive. There is also a lack of long-term evidence for its safety.

Factors that can influence testosterone levels

• Genes
• Age
• Environment
• Sleep
• Exercise
• Diet

A keto diet may burn more calories

The ketogenic diet is a high-fat, low-carb diet designed to keep the body in a near-constant state of ketosis, a metabolic state where the body creates ketones from fat to use as energy instead of sugar from carbs. While there is some debate about the effectiveness of keto for strength athletes, it is generally agreed that keto can help burn fat while retaining muscle.

Calories and keto

Calories are a measure of energy. Foods vary in their number of calories depending on the macronutrients present. Dietary fat has the highest calorie density, providing 9 calories per gram, while protein and carbohydrates contain 4 calories per gram.

The general consensus is that strict calorie counting on keto is unnecessary because ketosis teaches your body to burn fat at a greater rate, and the keto diet in and of itself has a satiating effect that leads to decreased hunger. However, it is still possible to go over your calories and deal with excess weight, so it might be a good idea to strike a balance between calorie control and a high-quality keto diet.

Factors affecting caloric intake on keto

How many calories you eat in a day on the keto diet will depend on several variables, including your activity level, sleep quality, stress, intake of processed foods, and alcohol consumption.

Tips for calorie management on keto

• Make more home-cooked meals
• Eat non-starchy fruits and vegetables
• Stop mindless snacking
• Prioritize protein in every meal
• Get sufficient sleep

Whether you count calories or not is a decision only you can make. Generally, calorie tracking on keto is not recommended as long as you prioritize whole and minimally-processed foods. However, if you are experiencing a weight loss stall, you might want to examine your snacking habits, stress, sleep, activity level, and alcohol intake.

Protein is key to building strength on keto

Protein is essential for building muscle and strength, and this is no different when following a keto diet. In fact, protein may be even more important when strength training on keto, as it can help to prevent muscle loss.

According to some sources, the recommended daily protein intake for those looking to build muscle is 0.7–0.9 grams of protein per pound of body weight (1.6–2.0 grams per kg). However, other sources suggest that those following a keto diet may need even more protein, with a recommended intake of 1 gram of protein per pound of body weight.

The Role of Protein in the Body

Protein is made up of amino acids, which are the building blocks of most human tissues, including muscle. Consuming adequate protein helps to repair and rebuild muscles, as well as maintain healthy skin, hair, nails, and bones. It is also important for creating hormones and enzymes, and can help to control weight by reducing appetite and preventing overeating.

Sources of Protein

Keto-friendly sources of animal protein include meat, poultry, seafood, eggs, and cheese. Tofu and soy-based products, as well as most nuts and seeds, are also good sources of protein on a keto diet, although some are higher in carbs than others.

Tips for Building Strength on Keto

To build strength on a keto diet, it is important to not only consume enough protein but also to engage in regular resistance training. Additionally, it may be beneficial to time your carb intake around your workouts, as this can help to improve performance. Finally, if you are struggling to meet your protein goals, consider using a protein powder supplement such as whey, casein, pea, or hemp protein.
