Deep dives
Importance of Skeletal Muscles for Health
The largest organ in the body is skeletal muscle, making up 40% of body weight. Skeletal muscles are essential for effective weight loss, boosting energy, burning fat, and promoting overall health. When skeletal muscles contract, they release myokines, which mediate communication between muscles and other organs, supporting bone health, brain health, and nutrient utilization. By prioritizing the health of skeletal muscles through dietary protein and exercise training, individuals can improve body composition, reverse diabetes, and fight heart disease and cancer.
The Role of Dietary Protein in Muscle Health
Dietary protein plays a crucial role in supporting skeletal muscle health. Protein is made up of 20 amino acids, including essential amino acids that are critical for muscle function. Animal-based proteins, such as lean beef, contain high-quality protein with essential amino acids that effectively stimulate muscle growth. For those following a vegetarian or vegan diet, plant-based protein powders can help balance amino acid profiles and support muscle health. Consuming 30-50 grams of protein at breakfast, along with adequate protein intake throughout the day, is important for maintaining and building healthy muscles.
The Benefits of Resistance Training
Resistance training, including weightlifting, is crucial for muscle health and body composition. It is recommended to engage in resistance training at least two days a week, focusing on multi-joint movements that involve multiple body parts. Women should not be intimidated by using heavier weights and can achieve effective muscle stimulation by going to fatigue. One high-intensity interval training (HIIT) session per week is also recommended to enhance muscle health and overall fitness. By combining a protein-forward diet with resistance training, individuals can experience improved muscle strength, body composition, and overall well-being.
Importance of Muscle-Centric Medical Approach
Prioritizing a muscle-centric medical approach to health and weight loss offers numerous benefits. By embracing a protein-forward diet and prioritizing exercise that strengthens muscles, individuals can experience better blood sugar regulation, higher energy levels, increased strength, and improved survivability against diseases. Skeletal muscles, being the largest endocrine organ system in the body, act as nutrient-sensing organs and play a crucial role in determining the overall quality of one's diet. As individuals age, the efficiency of detecting nutrients decreases, leading to conditions like sarcopenia, characterized by muscle wastage. However, this efficiency can be overcome and older muscles can function like younger ones by increasing dietary protein intake. Additionally, healthy skeletal muscles contribute to better metabolic health, protect against insulin resistance, improve brain health, and positively impact overall wellbeing.
Benefits of Protein and Resistance Training
Increasing protein intake and engaging in resistance training can have immediate benefits on daily life. Consuming around 30-50 grams of protein with each meal can result in improved energy levels, better blood sugar regulation, and reduced hunger. A protein-forward diet, along with controlling carbohydrate intake, helps maintain stable energy levels and prevents cravings for unhealthy foods. Protein also has a thermic effect, increasing metabolism and making it difficult to gain weight. Moreover, focusing on muscle health and engaging in resistance training leads to better body composition, with individuals losing fat and gaining muscle. Prioritizing skeletal muscle strength not only improves physical capabilities but also positively impacts metabolic health, brain health, and overall longevity.
