Dr. Amy West, a Sports Medicine Physiatrist, is at the forefront of a paradigm shift in understanding the root causes of joint pain, tendon issues, and other musculoskeletal problems. In her groundbreaking research and clinical practice, she has found compelling evidence that poor diets and metabolic health play a pivotal role in driving these conditions.
Traditionally, these musculoskeletal issues have been attributed solely to mechanical factors such as overuse, injury, or age-related degeneration. While these factors certainly contribute, Dr. West's work highlights the often-overlooked connection between nutrition, metabolism, and musculoskeletal health.

Show Notes:
02:00 CrossFit trains all three energy pathways: glycolytic, anaerobic, and aerobic. It is based on
function. Physiatry and CrossFit focus on function and living better.
08:00 Metabolic health impacts recovery, injury propensity, pain levels and physical function. Leptin
worsens osteoarthritis and pain issues.
12:15 Osteoarthritis is from the dysfunction of chondrocytes within the joint from inflammation and
fragility of cartilage within the joint. Metabolic disease causes a downward spiral. There is more
inflammation and more cartilage damage and more boney hypertrophy.
14:00 Trigger finger is often a first sign of metabolic disease. Tendons are also impacted by the
inflammation of metabolic disease. Healing process is impacted by the chronic inflammation of
metabolic disease.
14:54 Bone and bone density are impacted inflammation. This can appear as stress fractures. Treat the
fracture and the reason why.
17:00 Hemoglobin A1C is a marker of overall glycation in the body. Non-painful things become painful
with increased glycation.
17:30 The burden of age-related changes is dependent upon your metabolic state and physical
wellbeing. 96% of American adults have some sort of metabolic dysfunction, making them predisposed
to accelerated aging and physical decline.
23:00 Time is a major reason for not exercising. Short 20-minute bouts of more intense exercise are
easier to fit in and you get the same metabolic benefits in a shorter time.
23:40 Functional movement training increases strength and supports life functions. It uses multiple
joints and practices coordination.
24:30 Heavy resistance training induces the benefits of bone density and muscle integrity.
24:45 Osteosarcopenic obesity: as you gain weight, you lose muscle mass and bone.
26:00 Weakened tendons, tendonitis, and fibrosis are often a result of chronic inflammation from
metabolic dysfunction like diabetes. Arthritis is the leading cause of disability in the US.
27:25 Cortisone is a potent anti-inflammatory that brings short-term pain relief. It can raise blood sugar.
Repeated cortisone injections can further degrade cartilage, worsening arthritis. You can build up a
