The Importance of Skeletal Muscle for Longevity
Skeletal muscle is a critical factor in overall health and longevity. It plays a significant role in metabolic health, disease prevention, and immune function. The health of skeletal muscle outweighs the importance of body fat in determining overall well-being. Skeletal muscle is responsible for the secretion of molecules called myokines, which have anti-inflammatory effects and impact various bodily systems. Diseases related to metabolic health, such as diabetes and obesity, often have their roots in the decline of skeletal muscle health.
The Impact of Modern Lifestyle on Skeletal Muscle Health
Modern lifestyles, characterized by sedentary behavior and poor nutrition, have led to a decline in skeletal muscle health for many individuals. Chronic inflammation, pain, illness, metabolic dysfunction, and other potentially life-threatening diseases are linked to the deterioration of skeletal muscle. The focus on body composition and fat percentage as indicators of health overlooks the vital importance of maintaining and building skeletal muscle mass. Prioritizing skeletal muscle can improve metabolism, immunity, brain function, physical capability, mental health, and overall well-being.
The Need for Dietary Protein and Exercise to Counter Skeletal Muscle Loss
Dietary protein and exercise are essential in countering the natural loss of skeletal muscle that occurs with aging. Protein intake plays a significant role in muscle health, and the current dietary recommendations from 1968 do not reflect the optimal protein intake needed for healthy aging. Increasing protein intake beyond the minimum requirements can lead to better health outcomes. Regular exercise, even minimal exercise like walking and yoga, can help preserve and build muscle mass, protecting against muscle loss. Regardless of age, it is always possible to improve muscle strength and mass through targeted nutrition and exercise strategies.
Exercise and Autoimmune Conditions
Exercise, particularly resistance training, can play a role in managing autoimmune conditions such as Hashimoto's. While exercise alone cannot treat autoimmune conditions, it can have positive effects on overall health and mitigate some symptoms. Skeletal muscle mass and exercise help address issues like obesity, insulin resistance, and high blood sugar that can complicate autoimmune conditions. Exercise can also improve the functioning of skeletal muscle, utilizing glucose without the need for insulin, which is particularly important in conditions like hypothyroidism. However, it's important to understand that autoimmune conditions are complex, and exercise should be incorporated as part of a comprehensive treatment plan.
The Influence of Muscle Volume on Cancer Risk
Having healthy skeletal muscle mass can have a positive impact on reducing the risk of certain types of cancer, particularly obesity-related cancers. Obesity is a major risk factor for cancer, and maintaining a healthy body composition with adequate skeletal muscle mass can help combat obesity and its associated risks. Skeletal muscle also plays a role in managing inflammation and hormonal imbalance, which are factors that can contribute to cancer development. Additionally, exercise and resistance training can help in building and maintaining muscle mass, thus potentially reducing cancer risk.
Modern life is silently destroying our health. But what if the real culprit isn't too much fat, but too little muscle? Dr. Gabrielle Lyon, a physician researching the overlooked importance of muscle for metabolism, immunity, and disease prevention, reveals how the loss of muscle mass as we age secretly undermines health. In her groundbreaking book, Forever Strong: A New, Science-Based Strategy for Aging Well, Dr. Lyon shares how you can slow, stop and even reverse muscle loss through science-based nutrition and exercise.
Imagine if simply building muscle could lower disease risk and make you feel better. Dr. Lyon is on a mission to revolutionize aging. If you want to thrive in midlife and beyond, this conversation could change your life.
