Building Muscle: Gaining Weight Or Losing It?

does adding muscle increase weight

Adding muscle can increase weight, but it is not the only factor contributing to weight gain. When you start a new workout routine, you may experience temporary weight gain due to muscle inflammation, muscle glycogen, and water weight. Over time, as you build muscle mass, the scale may reflect a higher number. The rate of muscle growth and weight gain depends on various factors, including your diet, the type of workouts, and genetics. While building muscle can increase weight, it also offers benefits such as burning more calories, making it easier to maintain a healthy weight in the long run.

Weight training and diet

Diet

A well-rounded diet is crucial when building muscle. Generally, proteins should comprise between 30-40% of your diet, with carbohydrates making up 30-50%. It is important to eat a variety of foods to ensure your nutritional needs are met. Focus on lean protein sources such as chicken, fish, and turkey, which are low in saturated fat. For carbohydrates, opt for those with a low glycemic index, like nuts, beans, fruits, and sweet potatoes, as they provide sustained energy during workouts. Avoid excessive protein intake, as it can put unnecessary pressure on your body, especially your kidneys.

Timing of Meals

The timing of your meals is also important. Eat a snack or light meal 60-90 minutes before your workout to reduce abdominal discomfort. Consume fats and fibres at least three hours beforehand, as they take longer to digest. After your workout, focus on proper nutrition, hydration, and recovery. This is when supercompensation (muscle adaptation) occurs, so ensure you get 7.5-8 hours of sleep to speed up muscle development.

Weight Training

When it comes to weight training, resistance training is key to promoting muscle growth. This can be done using free weights, weight machines, your own body weight, or resistance bands. Train 2-3 times a week to allow for muscle recovery, as growth occurs during this period. Keep your workouts short and intense, and consider seeking professional advice to ensure correct form and reduce the risk of injury.

Supplements and Detoxes

Be cautious of powders, pills, and products that promise increased muscle mass, as these claims often lack scientific evidence. However, consider taking a liver and kidney detox supplement to maintain optimal organ function, as intense training and high protein diets can lead to a build-up of toxins.

Muscle repair and inflammation

Gaining weight after working out is common and can be attributed to several factors, one of which is muscle repair and inflammation.

Exercise, particularly weight training, causes structural damage to muscle tissue, leading to a condition known as exercise-induced muscle damage (EIMD). This damage initiates a repair process in the body, which allows muscles to grow stronger. However, during this repair process, inflammation occurs in the tissues. This inflammation is caused by a build-up of white blood cells in the damaged tissues. The inflammatory response is a natural physiological reaction to the micro-tears in the muscles caused by exercise. The body retains fluid around these tears to aid in the healing process, and this fluid has weight, leading to a temporary increase in body weight.

The relationship between inflammation and muscle repair is complex and involves various cellular and molecular processes. Inflammatory cells, including neutrophils and macrophages, play a role in both injury and repair. While macrophages have been shown to promote muscle damage, they may also contribute to repair and regeneration through growth factors and cytokine-mediated signaling. Muscle-derived nitric oxide can inhibit inflammatory cell invasion of healthy muscle tissue, protecting it from damage by inflammatory cells. On the other hand, muscle-derived cytokines can signal for inflammatory cell invasion, leading to a vicious cycle of tissue damage and inflammation. This cycle can result in severe inflammation, causing rhabdomyolysis and a sepsis-like systemic inflammatory response.

The repair and regeneration of skeletal muscle after injury involve the activation and proliferation of satellite cells, followed by their terminal differentiation. Mast cells also play a role in promoting immune cell recruitment and releasing inflammatory mediators such as TNFα, IL-1, and histamine. The damaged skeletal muscle has the intrinsic capacity to regenerate and repair itself through myogenesis.

While muscle repair and inflammation can cause temporary weight gain, it is important to note that building muscle mass also increases weight over time. The weight gain due to inflammation typically disappears within a day or so, and the repaired muscles come back stronger, aiding in fitness gains.

Water retention

Cortisol, a hormone released during times of stress, can also cause water retention. Research shows that a prolonged calorie deficit dramatically raises cortisol levels, which can lead to increased water retention and a bloated appearance.

It's important to note that water retention is typically temporary and should not be a cause for concern. In fact, it can be a good sign that your body is recovering properly from a challenging workout.

Calorie intake

Gaining muscle requires a calorie surplus, which means consuming more calories than your body burns. This is because building muscle requires energy, and any additional calories beyond what your body needs will be used to regrow damaged muscle tissue after a workout.

The exact number of calories needed to build muscle depends on your level of training, body composition, weight, sex, age, height, and physical activity level. For example, a 180-pound (82kg) male would need to consume 3600 calories per day to gain muscle mass, while a 20% increase in daily calorie intake is recommended for most people. On average, it takes 2,500 to 2,800 additional calories to build one pound of muscle, but this doesn't mean that increasing your intake by this amount will necessarily result in healthy gains. For some people, it is possible to build muscle in a calorie deficit, especially if they are new to resistance training or have a higher BMI.

To build muscle, it is recommended to consume a minimum of 0.8g of protein per kg of body weight, but this may need to be increased to 1.5-2.0g of protein per kg of body weight to support muscle development. Protein-rich foods such as cottage cheese, egg whites, Greek yogurt, and whey protein isolate are often recommended to help increase protein intake. Carbohydrates and fats are also important components of a muscle-building diet, and it is crucial to consume a balanced and nutrient-dense diet to promote healthy muscle growth.

Genetics

Genetic factors can also influence hormonal and muscular make-up, with individuals with lower testosterone levels potentially facing challenges in building muscle mass. In addition, genes can determine an individual's ability to develop certain types of muscle fibres, with sprinters possessing genes that allow them to develop more fast-twitch muscle fibres, while endurance runners have genetics that dictate muscle contraction speeds.

By understanding the genetic influences on muscle growth, individuals can adapt their training strategies to address any limitations. For instance, those with lower testosterone levels can incorporate exercises that stimulate testosterone production, such as compound movements, heavy lifting, and high-intensity resistance training. Additionally, by considering genetic measures such as enhanced weight loss genotypes, body composition genes, and testosterone levels, individuals can design personalised training programs that align with their genetic strengths and address potential limitations.

While genetics play a significant role, they are not the only factor influencing muscle growth. Environmental factors, such as physical activity and diet, also contribute to an individual's ability to build muscle. Therefore, even with a genetic predisposition, dedicated training and proper nutrition can still lead to significant results.

Frequently asked questions

Yes, adding muscle can increase weight, but it is not necessarily a bad thing. Muscle weighs more than fat, so you may see an increase in weight while your body fat percentage decreases. This is especially important when trying to lose weight, as it means you may not need to restrict your intake as much to continue losing fat.

Muscle growth occurs during recovery from resistance training. When you lift weights or do bodyweight exercises, your muscles endure tiny injuries throughout their fibres. When you rest, your body begins repairing these damaged muscle cells, and it is during this recovery process that your muscles grow and get stronger.

Building muscle takes time and consistency. True beginners might see muscle growth within six weeks of starting a resistance training program, while advanced lifters may see results within six to eight weeks of changing their strength training regimen.
