Your symptoms are also addressed with great importance in modern medicine under the names sarcopenia or potential nutritional imbalance. Beyond simply losing weight, it refers to a state where muscle, the core engine of our body, is gradually lost, leading to a decline in overall physical function. In particular, age-related muscle loss in older adults, termed sarcopenia, is well known, but cases occurring in adults in their 30s and 40s despite sufficient nutritional intake are also increasing.
Several complex causes operate at the root of this phenomenon. First is a state of chronic inflammation. Stress, irregular dietary habits, and sleep deprivation expose the body to continuous inflammatory responses, and this inflammation hinders muscle protein synthesis and promotes proteolysis. It is as if muscles are constantly being dissolved inside the body. Second is an imbalance in gut health. An imbalance in the gut microbiota, or microbiome, not only prevents nutrients from being properly absorbed from food, but also increases intestinal mucosal permeability, allowing inflammatory substances to enter the bloodstream. No matter how well you eat, it becomes like pouring water into a leaking vessel.
Third is hormonal imbalance. With aging, the secretion of hormones vital for muscle maintenance, such as growth hormone, testosterone, and estrogen, can decrease, and excessive secretion of cortisol due to chronic stress accelerates muscle protein breakdown. Fourth is a deficiency in micronutrients such as vitamin D, magnesium, and zinc. These micronutrients serve as essential coenzymes for numerous biological reactions, including muscle protein synthesis, energy production, and immune function, yet they are easily lacking in modern individuals due to diets centered on processed foods or excessive caffeine intake.
Ultimately, when the body reaches a state where it cannot properly use food no matter how much it takes in, it perceives this as an emergency, reducing activity levels and inducing lethargy to conserve energy. Breaking this vicious cycle is crucial, and rather than simply eating a lot, you need to focus on eating properly, digesting properly, and utilizing nutrients properly. Paying close attention to your body's subtle signals is truly essential.
