Exercise And Keto: Weight Loss Partners?

The ketogenic diet is a low-carb, high-fat, and moderate-protein diet that has been linked to several health benefits, including weight loss. While the keto diet can be effective for weight loss, some people may struggle to lose weight on it due to various reasons. One of the main reasons is not achieving ketosis, a metabolic state where the body burns fat for energy instead of glucose. This can be caused by consuming too many carbs or too much protein, as well as not tracking calorie intake and engaging in high-intensity exercises. To maximize weight loss on the keto diet, it is important to combine it with regular exercise, create a calorie deficit, manage stress, and consume nutritious, low-carb, and whole foods.

Exercise can speed up ketosis by depleting glycogen stores

A 2018 review article mentions that repeated sprinting — a high-intensity activity — quickly lowers glycogen stores despite its short duration. The same thing happens with endurance training, which lasts several hours.

Exercising while in ketosis accelerates weight loss. This is because glycogen stores run out the longer and harder you work out. Combined with a very low-carb diet, which also reduces glycogen, you’ll take your weight loss to the next level.

Besides that, working out in ketosis leads to greater weight loss by preserving lean muscle mass. The more lean muscle you have, the higher your resting metabolic rate or resting energy expenditure (REE). This means your body burns more calories at rest, thanks to your muscle tissue, which is more metabolically active compared to fat tissue.

While exercise speeds up ketosis, it’s important to note that a lack of carbohydrates may negatively affect your exercise performance. Having high levels of glycogen is necessary for strenuous workouts to boost your output. This explains why exercises that entail bursts of energy can be more difficult for people on a ketogenic diet.

Exercise can help preserve lean muscle mass

Another way exercise helps preserve lean muscle mass is by improving bone health. Resistance training supports bone growth and increases bone density, which is crucial for reducing the risk of osteoporosis and fractures, especially as we age.

Exercise also plays a role in maintaining lean muscle mass by boosting metabolism. Muscle is a metabolically active tissue, meaning it burns calories even at rest. Therefore, having more muscle mass can contribute to a higher resting metabolic rate, making it easier to manage your weight.

Furthermore, exercise can help improve functional strength and performance in daily activities, leading to a better quality of life and independence, especially for older adults. For example, focusing on improving your muscle power, or how quickly and efficiently you move, can enhance your overall physical function.

Finally, exercise can help preserve lean muscle mass by regulating glucose metabolism and insulin sensitivity. Muscle is a critical regulator of glucose metabolism, and resistance training helps preserve muscle mass, reducing the risk of metabolic disorders such as diabetes.

Low-intensity exercises are more suitable for keto

The ketogenic diet is a very low-carb, high-fat, and moderate-protein diet that has been linked to several health benefits, including improved blood sugar control and decreased hunger. However, its impact on athletic performance is still debated. While some claim that keto can boost fat-burning and endurance, others argue that it could drain energy levels and hinder muscle growth.

When starting a low-carb or keto diet, the body needs time to adjust to burning fats instead of carbs for fuel. During this transition, individuals may experience fatigue and reduced athletic performance. Therefore, it is recommended to start with low-intensity workouts like slow jogs, yoga, stretches, and conditioning until the body fully adapts to the low-carb diet.

Low-intensity, steady-state (LISS) exercises are particularly beneficial for those on a keto diet. LISS workouts are performed at a moderate intensity, allowing individuals to maintain the activity for an extended period, typically 30 to 60 minutes. This type of exercise maximizes calorie burning and can include activities such as jogging, biking, rowing, and yoga.

In contrast, high-intensity exercises that rely heavily on glycogen (derived from carbs) may be more challenging for those on a keto diet. Examples of such exercises include sprinting, boxing, swimming laps, and jumping rope. The body's glycogen stores are compromised during ketosis, making it difficult to sustain high-intensity activities.

By focusing on low-intensity exercises, individuals on a keto diet can maximize the benefits of the diet while minimizing the negative impact on athletic performance. This approach allows for a gradual adaptation to the body's new fuel source and helps avoid the potential energy drain associated with high-intensity workouts.

Additionally, the keto diet may enhance endurance, boost fat-burning, and speed up muscle recovery. However, it is important to note that the diet may also impair muscle growth due to potential protein restrictions and lower calorie intake.

Resistance training is the most effective for muscle preservation

Resistance training is a type of exercise that uses force to create muscle contractions and increase skeletal muscle size, strength, and endurance. It is based on the idea that when the body is forced to overcome a resistance force, its muscles will adapt and become stronger. This type of training can be done using weights, bands, or even your body weight as resistance.

Resistance training is highly effective for muscle preservation because it creates small tears in the muscle fibers that the body then repairs and regenerates, leading to muscle growth. Additionally, resistance training increases the levels of growth hormone, insulin-like growth factor, protein, and other nutrients in the muscles, which further aids in muscle repair and strength enhancement.

One of the key principles of resistance training is the progressive overload principle, which states that to continue gaining strength, individuals should work out until it becomes challenging to perform another repetition. This challenges the muscles and promotes growth. It is recommended to vary the exercises, weights, and number of repetitions and sets performed to maintain and improve strength gains.

The benefits of resistance training go beyond muscle preservation and include improved joint function, increased bone density, enhanced balance and flexibility, reduced risk of injury, and improved mental health. It is an effective tool for preventing age-related muscle loss and improving overall physical and mental well-being.

Sleep is important for weight loss

Thomas Delauer is a well-known figure in the health and fitness industry, having transformed his body and his life through dedication to diet and exercise. He promotes a ketogenic diet and intermittent fasting as a means to lose weight and improve health. While exercise is an important component of any weight loss journey, sleep is also a critical, and often overlooked, factor.

Sleep is essential for regulating the hormones that control hunger and appetite. A lack of sleep can lead to increased levels of ghrelin, the hormone that stimulates hunger, and decreased levels of leptin, the hormone that contributes to feelings of fullness. This dysregulation can lead to increased appetite and cravings for high-calorie, high-carbohydrate foods, making it difficult to stick to a healthy diet.

Sleep deprivation can also lower your metabolism, making it harder to burn calories and contributing to weight gain. Poor sleep has been linked to increased oxidative stress, glucose intolerance, and insulin resistance, all of which can impact weight management. Additionally, when you're tired, it's easier to make unhealthy choices like skipping exercise and opting for convenience foods or takeout.

To support weight loss efforts, it's important to establish healthy sleep habits. This includes maintaining a regular sleep schedule, sleeping in a dark room, avoiding heavy meals and alcohol before bed, and reducing stress. Improving sleep quality can have a positive impact on weight loss and overall health.

In summary, sleep plays a vital role in maintaining a healthy weight. By regulating hormones, controlling appetite, and supporting metabolism, adequate sleep can help individuals make healthier choices and maximize the benefits of their diet and exercise routines.
