Weight Loss Stalling On Keto: What You Need To Know

The ketogenic diet is a weight-loss diet that involves cutting down on carbohydrates and increasing fat intake to place the body in a state of ketosis, where it uses stored fat instead of carbohydrates as its primary fuel source. While the keto diet has been credited with weight loss and other health benefits, it may not be the best option for those looking to build muscle through weight lifting.

During ketosis, the body breaks down stored fat into ketones as fuel. This process can cause a decrease in muscle fullness and hydration, as each gram of carbohydrate is assigned three grams of water by the body. Additionally, the high-fat content recommended in the keto diet may not leave enough room for protein, which is essential for muscle growth and repair.

The keto diet may also impact weightlifting performance. Carbohydrates are stored in the muscles as glycogen, providing fuel for intense weightlifting sessions. A lack of carbohydrates in the keto diet can lead to decreased glycogen stores and compromised athletic performance. The diet may also cause side effects like fatigue, dizziness, and nausea, especially during the transition period.

While it is possible to build muscle on a low-carb diet, it may take longer, and the body can take weeks or even months to fully adapt to ketosis. For those looking to optimise their weightlifting performance and build muscle mass, a diet with sufficient carbohydrates and protein may be a better option.

Weight Lifting on Keto May Lead to Poor Performance

The ketogenic diet is a high-fat, low-carbohydrate diet that has been credited with weight loss and other health benefits. However, there is some debate about whether it can aid strength athletes. The diet is designed to put the body in a state of ketosis, where it burns fat instead of carbohydrates for fuel. While this may be beneficial for some endurance athletes, it may not be the best choice for strength athletes who require high-rep activity or prolonged periods of exercise.

The Ketogenic Diet and Ketosis

The ketogenic diet, or keto, involves cutting down on carbohydrates and increasing fat intake, with typically 70% of calories coming from fat, 25% from protein, and just 5% from carbohydrates. This shift in fuel sources causes the body to enter a state of ketosis, where it burns stored fat instead of carbohydrates for energy.

The Impact of Keto on Strength Athletes

The keto diet may not be the best choice for strength athletes who require high-rep activity or prolonged periods of exercise. This is because the body relies on carbohydrates as its primary fuel source during high-intensity or prolonged exercise. When in ketosis, the body may not be able to use stored carbohydrates effectively, leading to compromised athletic performance.

The Downsides of Keto for Weightlifters

According to experts, a ketogenic diet can lead to poor performance in weightlifters due to decreased muscle fullness and hydration. This is because, for every gram of carbohydrate, the body assigns three grams of water. Additionally, a standard ketogenic diet may not provide enough protein, which is essential for muscle growth and repair.

The Transition to Keto

It is important to note that there is a transition period when switching to a keto diet, and side effects such as fatigue, dizziness, headache, and nausea may occur until the body adjusts. It can take weeks or even months for the body to fully adapt to ketosis.

The Bottom Line

While the ketogenic diet may be beneficial for some endurance athletes, it may not be the best choice for strength athletes who require high-rep activity or prolonged periods of exercise. Weightlifters following a keto diet may experience decreased performance and may be at a higher risk of injury due to compromised form.

Keto May Not Be Suitable for High-Repetition Training

The ketogenic diet is a high-fat, low-carbohydrate diet designed to put the body in a state of ketosis, where it burns fat as fuel instead of carbohydrates. While this can have weight-loss benefits, certain workouts may become more challenging.

The Impact of Keto on Exercise Performance

According to Andy Galpin, a professor of kinesiology, there is "very little evidence" that the ketogenic diet is beneficial for exercise performance. In fact, the diet may negatively impact certain types of exercise.

High-Intensity Exercise and Keto

High-intensity exercises, such as strength training, sprinting, and other sports that require short bursts of intense movement, are primarily fuelled by carbohydrates. The human body stores carbohydrates in muscle cells as muscle glycogen, which serves as an immediate fuel source during high-intensity activity.

On the keto diet, the body burns fat for energy instead of carbohydrates, and fat is not as easily burned, making the process less efficient. As a result, the keto diet tends to limit performance during high-intensity workouts.

A small study from February 2017 found that participants' performance in endurance capacity and peak power decreased after following a ketogenic diet for six weeks.

The Impact of Keto on Bodybuilding

Bodybuilding, which often involves high-intensity and high-volume training, may be negatively affected by the keto diet due to the reduced availability of carbohydrates for fuel.

Andrea N. Giancoli, MPH, RD, states that for intense weightlifting, a ketogenic lifestyle is not compatible with a bodybuilding regimen. The body needs carbohydrates to power through strength-training sessions, and a lack of carbohydrates can result in decreased glycogen stores in the muscles, compromising athletic performance.

Dominic D'Agostino, Ph.D., a national-qualified bodybuilder, notes that a keto diet can lead to poor performance in bodybuilding due to decreased muscle fullness since each gram of carbohydrate is assigned three grams of water by the body. Additionally, the standard ketogenic diet may not provide enough room for protein, which is essential for muscle growth and repair.

The Bottom Line

While the keto diet may be suitable for low-intensity, steady-state workouts, it may not be the best choice for high-repetition training or exercises that require high-intensity bursts. Bodybuilders and athletes engaged in high-volume training may experience decreased performance and compromised muscle growth due to the limited availability of carbohydrates as fuel.

Keto May Not Be the Best Diet for Muscle Gain

The ketogenic diet has become increasingly popular for weight loss. However, there is a common misconception that it may not be suitable for building muscle. So, can you build muscle on keto?

Muscle Protein Synthesis

Firstly, it's important to understand how our bodies build muscle. Muscle protein synthesis is the process by which our bodies build new proteins and is essential for muscle growth. This process is activated by specific types of exercise, such as resistance training or weightlifting, and certain nutrients from food.

MTOR and Muscle Building

One of the key drivers of muscle protein synthesis is mTOR, a nutrient and mechanical force sensor. When we lift heavy weights, mTOR is activated, stimulating muscle protein synthesis and preventing protein breakdown. The more we activate mTOR, the more muscle growth and strength we can achieve.

Amino Acids

Amino acids, often referred to as the "building blocks" of proteins, are essential for muscle growth. Branched-chain amino acids (BCAAs) are particularly effective at causing muscle hypertrophy and preventing muscle breakdown. Consuming BCAAs, especially leucine, after a workout can help maximise muscle protein synthesis.

The ketogenic diet is often criticised for being low in carbohydrates, which are thought to be necessary for muscle growth. Carbohydrates stimulate insulin production, which, in turn, activates mTOR and leads to increased muscle protein synthesis. However, research has shown that consuming protein alone after a workout is just as effective as combining protein with carbohydrates.

Furthermore, the idea that carbohydrates are necessary to maintain glycogen levels during exercise, especially for endurance athletes, has been challenged. Keto-adapted athletes have been found to maintain similar levels of stored muscle glycogen as athletes on high-carbohydrate diets and are equally capable of replenishing glycogen levels after exercise.

How Keto Helps You Build Muscle

So, where did the idea that you can't build muscle on keto come from? One reason is the misconception that low-carb diets fail to stimulate insulin and IGF-1, hormones that promote muscle protein synthesis. Another reason is the belief that keto restricts protein intake, which is essential for muscle growth.

However, research suggests that keto can support muscle growth and prevent muscle breakdown. For example, a study found that a group of young men who followed a low-carb diet and a resistance training program for 10 weeks gained lean body mass and reduced fat mass, with similar results to a group on a normal diet.

Additionally, keto can help optimise body composition by increasing fat-burning capacity and reducing body fat percentage. This can lead to improved lean muscle mass.

Common Keto Bodybuilding Challenges

Despite the potential benefits of keto for muscle growth, there are some challenges to consider. Firstly, it can be difficult to consume enough calories and protein on keto due to the filling nature of the diet. It's important to ensure you're eating enough total calories and protein to support muscle growth and repair.

Inconsistent meal planning is another challenge. It's crucial to have a consistent macro plan, even on rest days, to ensure your body has the nutrients it needs to recover and build muscle.

How to Build Muscles on the Keto Diet

To build muscle on keto, focus on the following:

• Eat enough protein and calories: Prioritise protein and ensure you're consuming enough calories to be in a maintenance or surplus state.
• Do intense workouts with progressive overload: Challenge your body with weightlifting or bodyweight exercises, increasing the weight, reps, or sets as you get stronger.
• Prioritise rest and recovery: Get sufficient sleep, reduce stress, and engage in active recovery exercises like walking or yoga.
• Stay hydrated and maintain adequate electrolyte intake: Drink plenty of water and include potassium- and magnesium-rich foods in your diet.

In conclusion, while keto may not be the first diet that comes to mind for muscle gain, it can certainly support muscle growth when combined with a well-planned nutrition and workout routine.

Keto May Cause a Loss of Muscle Fullness

The ketogenic diet is a high-fat, low-carb approach to losing weight that has become one of the most popular ways to shed pounds. However, it is extremely regimented and very difficult to stick to. The diet typically reduces carbohydrate intake to less than 50 grams per day and calls for a moderately increased intake of protein and fat. On keto, you get 70% to 80% of your calories from fat, about 20% from protein, and as little as 5% from carbs.

The ketogenic diet has been associated with a loss of muscle fullness. This may be due to the restricted amount of protein on the keto diet. Protein is essential for building muscle, and if you're not getting enough, your body may break down muscle to get the protein it needs.

Causes of Muscle Loss on Keto

• Sarcopenia: This is a natural and involuntary loss of muscle mass that occurs with aging. According to research, muscle mass and strength may begin to decline as early as age 40 and continue to decline with age, resulting in a 50% muscle loss by age 80.
• Not Eating Enough Protein: Muscles are made up primarily of protein. When you don't get enough protein, your body may break down muscle to get the protein it needs. To maintain muscle mass, it is recommended to consume 0.36 grams of protein per pound of body weight for an inactive person and 1 gram (or more) per pound of body weight if you're active or do intense workouts.
• Too High of a Calorie Deficit: On a restrictive keto diet, it's possible to limit food intake so much that you don't get enough calories. When you're not getting enough fuel, your body may break down muscle to get the energy it needs.
• Training Incorrectly: A mixture of cardio and strength training is ideal for maintaining muscle mass. If your training is cardio-heavy or intense at the expense of strength training, you may experience muscle loss. Cardio training relies on the same resources needed for building muscle, so if you deplete those resources with cardio, you won't have enough left for building muscle.
• Not Training Enough: If you don't train hard enough or often enough, you'll miss out on the muscle-building benefits of exercise. Inactivity or low activity can lead to muscle loss.

Preventing Muscle Loss on Keto

• Consume Optimal Amounts of Protein: Skimping on protein can lead to muscle loss. It is recommended to consume between 0.7 to 0.9 grams of protein per pound of body weight to build muscle.
• Prioritize Strength Training: Muscle building doesn't happen when you're sedentary. Exercise, specifically strength training and resistance training, is necessary to build and maintain muscle.
• Don't Cut Carbs Completely: You still need carbs on a keto diet, but choose healthy carbs like unsweetened coffee and tea, cocoa, and dark chocolate. Aim for about 50 grams of carbs per day.

The Bottom Line

The ketogenic diet may cause a loss of muscle fullness, especially if you're not consuming enough protein or engaging in adequate strength training. To prevent muscle loss on keto, ensure you're consuming enough protein, incorporating strength training into your routine, and not completely eliminating carbs from your diet.

Keto May Not Be Compatible with Intense Weightlifting

The ketogenic diet, or keto, is a high-fat, low-carb diet designed to keep the body in a near-constant state of ketosis. In this state, the body uses fat instead of sugar from carbs as its primary energy source. While keto can be an effective weight-loss strategy, it may not be the best diet for intense weightlifting.

Keto and High-Intensity Exercise

Keto may not be the best diet for high-intensity exercise, including weightlifting. The human body stores carbohydrates in the muscle cells as muscle glycogen, which becomes an immediate fuel source for any activity that requires intense movement, such as weightlifting. On a keto diet, the body burns fat for energy instead of carbohydrates, and fat is not as easily burned, making the process less efficient. As a result, keto tends to limit performance during high-intensity workouts.

Carbohydrates and Muscle Building

Carbohydrates are essential for muscle building. They provide fuel for the muscles, which store them as glycogen. A lack of carbohydrates in the diet can lead to decreased glycogen stores in the muscles, resulting in compromised athletic performance. In addition, insulin, which increases in response to carbohydrate intake, stimulates muscle protein synthesis and reduces muscle protein breakdown.

Keto and Muscle Building

While it is possible to build muscle on a keto diet, it may take longer. A standard ketogenic diet may not provide enough protein, which is the body's basic building block for muscle. Intense weightlifting requires a consistent supply of protein throughout the day for optimal muscle growth, maintenance, and repair.

Transitioning to Keto

There is a transition period when switching to a keto diet, and during this time, individuals may experience side effects such as fatigue, dizziness, headache, and nausea. In addition, keto may decrease muscle fullness since the muscles won't be as hydrated; for every gram of carbohydrate, the body assigns three grams of water.

Alternative Diets for Weightlifting

For individuals who engage in intense weightlifting, a diet that includes quality carbohydrates and sufficient protein may be a better option than keto. Carbohydrates containing fiber, like beans, quinoa, and whole-grain bread, are good choices. For muscle growth, 20 grams of protein is generally considered optimal.
