Intro 2:49 There is a cycle with aging of reduction of muscle mass and increase of fat mass.  3:30 Hormonal changes of aging change body composition, leading to the acceleration of muscle loss. 5:00 Diets should be paired with resistance and aerobic training. 6:00 Changes in muscle precedes fat gains.  7:30 Focus on muscle and protein intake. 9:55 Adipocyte number is set during adolescence.  10:10 Health at any size is a fallacy. 10:51 Fat cells become hypertrophied and become necrotic and die. 11:30 Excessive amounts of energy cause fat cells to become inflamed. 12:05 Overfilled fat cells spill lipids, and greatly affect your liver. 12:45 Dead fat cells cause metabolic immune debris. 14:00 Immune cells infiltrate your fat, creating inflammation. 14:45 Exercise helps prevent fat cell inflammation. 15:30 Belly fat is not benign. 15:50 Obesity causes changes in muscle tissue. 17:30 Walking builds capillary and mitochondrial density in muscles. 19:00 Leg training provides greater anabolic responses. 20:00 Age-related loss of muscle strength is 3x faster than loss of muscle mass. 21:30 Compound movements move 2 or more joints at the same time. 22:40 Combination of diet and exercise may be the most effective intervention.
