0:26 You become less glucose tolerant as you age.
0:49 Insulin resistance amplifies the rate of acceleration in the wasting of muscle.
1:05 Muscle stem cells, as you age, cause your muscles to behave like fat tissue.
1:25 Muscle tissue of people who are insulin resistant or diabetic resembles that of age-related sarcopenia.
1:35 Atrogenes drive atrophy.
1:52 60 to 80% of post meal glucose is deposited in skeletal muscle. If there is no muscle, it gets converted into fat.
2:45 About 83% of American adults suffer from some sort of insulin resistance.
3:25 Insulin resistance favors muscle protein catabolism, at the expense of muscle protein synthesis.
6:18 Insulin resistance activates atrophy genes.
6:50 You become more insulin resistant and lose muscle mass as you age.
7:40 Hyperinsulinemia accelerates atherosclerosis (heart disease) and cancer.
10:58 Insulin resistance leads to a decline of mTOR activation in your muscle.
13:00 About .1% of all of your muscle tissue is turning over at any point. Progenitor stem cells are involved in the maintenance and regeneration of your muscles.
14:00 Muscle is the most active site of protein metabolic processes in the body.
14:25 You may get better gains from exercise and resistance training by being more insulin sensitive.
15:10 Background inflammation from insulin resistance can accelerate muscle atrophy.
16:00 To become more insulin sensitive…
