Just wrote everything and lost it. My tablet is acting up and patience is dwindling.

Broda Barnes books: Solved: the riddle of heart attacks; Hypothyroid the unsuspected illness. He states hypoT people don't store sugar as well and t4 to t3 conversion is diminished making exercise problematic. Also hypoT people lose sodium much quicker through urine making magnesium deficient. BB suggests based on evidence and his experience as an MD that about 50% of the population is hypothyroid. That would make it very common.

Recommended dietary allowance for vitamin E: relation to dietary, erythrocyte and adipose tissue linoleate.
Witting LA, Lee L.
The general trend toward increased consumption of polyunsaturated fatty acids is apparent in the linoleate level of adipose tissue (13.0 plus or minus 1.3%) and erythrocyte lipids (14.0 plus or minus 1.9%) in the present group of female undergraduate student volunteers compared to values reported in the early 1960’s. On the basis of the level of linoleate in their diets (19.5 plus or minus 0.8%), it is also apparent that further increases in tissue lipid linoleate levels are to be anticipated, which in turn will result in an increased requirement for vitamin E.
The person who does aerobics 5 days a week will see slow progress as cortisol will remain high and t3 declines. They may have some increased strength and increased glycogen storage ability unless they are hypothyroid. Fat loss may be minimal to significant but following the SAID principle, if you are training to burn fat you will store it more readily to use it for fuel thanks to cortisol.
The sedentary person, assuming is in good health, will be fine as long as they enjoy life, get adequate sunshine and eat according to their needs. Especially at high altitudes as co2 is retained. Centenarians are usually sedentary and give no though to diet and lifestyle.
