Show Notes:
01:00 There are cellular changes within adipose tissue and skeletal muscle linked with aging.
01:47 As fat cells get older, they hold fat more tightly.
01:55 There is infiltration of immune cells within fat tissue.
02:35 Mitochondrial function decreases with aging.
03:00 Exercise purges senescent cells.
03:50 Serum DHEA decreases with age.
04:52 Hormonal changes in aging cause fat cells to misbehave leading to metabolic derangement.
08:45 Reduced testosterone and DHEA effect post meal fat storage in men.
09:40 Your upper body is more sensitive to storing lipids after a meal but can become overfilled.
10:30 Fat tissue inflammation can be linked to reduced physical activity.
11:12 As you get older and stop exercising, decrease protein, your fat cells become infiltrated and enlarged.
12:25 The more body fat you have, the more proinflammatory immune cells you have within your fat tissue.
13:20 Overfilled fat cells cause muscle cells to onboard more fat.
14:00 Physical training has a huge impact on preserving muscle protein synthesis.
15:50 Exercised muscles become more sensitive to nutrients.
16:30 Increase your protein intake as you get older.
17:30 Protein intake should be between 1.2 and 1.5. Grams per kilo of ideal bodyweight per day.
18:10 Fast twitch muscle fibers are preferentially lost with aging.
