Entry 01/10/09

Exercise: Couldn't work it in today. I really need to. It is important to weight loss. Not as important as eating correctly but there is some interdependence between the two. I find this especially true as I age. I need exercise to counteract the normal muscle atrophy of aging and the decrease in metabolism. Muscle is very important to burning calories. The more muscle we have the more calories burned even while we sleep. Exercise also helps us avoid negative emotions which can lead to eating to make us feel good.

After our early twenties, our bodies begin aging. All our joints and organs are past their prime. Exercise helps slow the onset of arthritis and other joint problems. Joint cartilage depends on synovial fluid for its nutrition since it has no blood vessels. Synovial fluid is forced into the cartilage surfaces when the joint is loaded, as in physical activity. Joint cartilage functions in an elastic manner during short term loading. The cartilage becomes temporarily deformed when long term loading forces water out of the cartilage. It returns to its original shape when unloaded, when water is again drawn into the cartilage. The alternate compression and decompression along with the pumping of synovial fluid due to physical activity is partly responsible for nutrition to the cartilage.

Breakfast: Boiled egg, 2 slices of toast with margarine and tiny bit of strawberry preserves. Coffee, with creamer and sweetener.

Lunch: Bowl of Chilli and Bologna sandwich, 6 oz. skim milk
