✓Well SupportedSarcopenia is estimated to cause a 1% loss of skeletal muscle mass per decade after age 50, but it may start earlier in the 30s and progress faster.✓Well SupportedOlder adults may be unable to regain 4-5 pounds of lean tissue lost following immobility from a fracture.◐Partially SupportedLack of sufficient skeletal muscle is a common factor in patients with dementia and other chronic diseases.◐Partially SupportedChronic diseases can be characterized as a loss of muscle, similar to neurodegenerative diseases involving neuron loss.Partially Supported

Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

Skeletal muscle is the root metabolic cause of many chronic diseases.

◐Partially SupportedSkeletal muscle mass is directly related to strength, and muscle loss is more impactful than fat gain with aging.

◐Partially SupportedOne night of sleep restriction can reduce muscle protein synthesis by approximately 18%.

✓Well SupportedMRI is a more effective method than DEXA for measuring skeletal muscle mass, though it is less accessible and more expensive.

◐Partially SupportedAge-related muscle loss is primarily caused by lifestyle factors including inadequate nutrition and insufficient exercise, not inevitable aging.

✓Well SupportedSupporting muscles nutritionally requires high-quality proteins and nutrient-dense foods, alongside resistance training.

◐Partially SupportedLow-level inflammation, poor food quality, and lack of sleep contribute to negative health outcomes, including potentially impacting muscle protein synthesis.

◐Partially SupportedExcessive dieting and exercise without adequate nutrition can lead to muscle loss, impairing blood sugar regulation, insulin sensitivity, and triglyceride levels.

✕Not SupportedWestern medicine lacks awareness regarding the role of dietary accumulation of seed oils in age-related decline and instead focuses on prescribing medications for resulting conditions.

◐Partially SupportedAge-related insulin resistance and decrepitude are primarily caused by the dietary accumulation of garbage, including excess linoleic acid from seed oils, which accumulates in mitochondrial membranes.

◐Partially SupportedSarcopenia is not listed as a cause of death by the CDC, despite its relation to mortality from heart disease and cancer.

◐Partially SupportedThe capacity to build muscle and leverage youthful hormones decreases with age, but tissue growth stimulation does not disappear until death.

◐Partially SupportedA deuterated creatine pill (D3 creatine) will enable direct measurement of muscle mass via a urinary test.

◐Partially SupportedSkeletal muscle is the only tissue that individuals can actively influence through exercise and nutrition to maintain health.

◐Partially SupportedDietary protein intake is likely insufficient and diets are too low in nutrient density, specifically iron and B12, for older adults.

◐Partially SupportedAging is associated with a decline in protein turnover and proteostasis, and modern lifestyle factors do not adequately support these processes.

◐Partially SupportedNutritional habits established in youth are not adjusted to accommodate changing physiology with age, leading to an imbalance between exercise, movement, and nutrition.
