From Body Fat to Muscle Health: The Paradigm Shift Needed to Address Obesity
The Midlife Muscle Crisis
Dr. Lyon's perspective on obesity is rooted in her experiences as a geriatric and nutritional science fellow at Washington University. During her clinical practice, she saw thousands of patients who were overweight or obese, but one stood out to her: a woman named Betsy. Betsy had struggled with the same 20 pounds throughout her life and had spent a lifetime yo-yo dieting, being told to cut back on calories and focus on the pathology of fat. When Dr. Lyon imaged Betsy's brain, she saw the beginning of an Alzheimer's brain. Dr. Lyon realized that Betsy's problem was not her weight, but her muscle health. Betsy was not overfat, but under-muscled.
Dr. Lyon argues that the obesity epidemic is not a problem of excess fat, but a midlife muscle crisis. According to Dr. Lyon, muscle is the pinnacle of health, and the more healthy muscle a person has, the stronger their capacity, the greater their energy, and the better their ability to fight. Muscle is also the organ of longevity, with the research showing that the greater a person's muscle mass, the greater their survivability against nearly every disease.
The Importance of Muscle Health
Muscle is a complex organ with many functions. It is the body's metabolic sink, responsible for carbohydrate metabolism and fat burning. It is also the site for energy metabolism and offers an augmented immune system. However, a lifetime of overeating and under-exercising can lead to clogged-up muscle, which no longer functions efficiently. Resistance exercise and dietary protein are the two primary ways to support muscle health.
Resistance Exercise and Dietary Protein
Resistance exercise is the closest thing to the fountain of youth, offering numerous benefits to muscle health, such as improving blood glucose, metabolic markers, and blood pressure. However, only 23% of adults meet their exercise requirements, and many people are not aware of the importance of resistance exercise in maintaining muscle health.
Dietary protein is also crucial for muscle health, as muscle is made from protein. High-quality protein from sources such as lean meats, chicken, fish, eggs, and dairy is recommended, with 40 grams of high-quality protein at the first and last meal of the day recommended for all patients. Unfortunately, many women over 65 do not meet their daily protein requirements, with 40% falling short.
The Paradigm Shift
Dr. Lyon argues that the medical paradigm needs to shift from a focus on body fat to a focus on muscle health. The obsession with body fat has led to an increase in obesity, as it has led to a misguided approach to weight loss that focuses on calorie restriction, rather than the preservation and improvement of muscle health.
The Bottom Line
In conclusion, Dr. Gabrielle Lyon's message is clear: we need to shift our focus from body fat to muscle health. Our current health crisis is not due to an obesity epidemic, but rather a midlife muscle crisis. The story of Betsy, a patient who struggled with weight her whole life and suffered from the consequences of yo-yo dieting, serves as a poignant reminder of the importance of prioritizing muscle health.
Muscle is not just about looking good or performing athletically. It is an essential organ of longevity that plays a crucial role in our metabolism, energy levels, and immune system. By making resistance exercise and dietary protein a priority, we can support the health of our muscles and improve our overall health and wellbeing.
Dr. Lyon's message is particularly relevant in today's world, where sedentary lifestyles and poor dietary habits have become the norm. By taking action and making small changes to our lifestyle, we can improve our muscle health and protect ourselves against disease.
Ultimately, Dr. Lyon's advocacy for muscle-centric medicine is a call to action for the medical community to shift its focus and prioritize the health of our muscles. It is time for a paradigm shift, and by working together, we can build a healthier future for ourselves and our communities.
