That's very interesting, Yorksman, thanks! Michael Mosley did one of those centrifugal blood samples on his doc about exercise - ate a massive Scottish full breakfast on both days, exercised on only one of them and compared the blood/fat ratio, quite a startling demo of a proven phenomenon.Yes and whilst most people think about getting fitter, a stronger heart and lung function, getting in trim etc there are also major beneficial effects on the blood chemistry. You can literally see this in a centrifuged blood sample. Excercise releases certain hormones which trigger the production of certain enzymes which change the chemistry by lowering various lipids. They last for about 36 hours so daily exercise keeps them nicely topped up. Moreover, to get this benefit, you only need to do 200kcal to 250 kcal per day, doing more after that won't change much, although it will obviously still helps in fitness levels etc.
"The role of physical activity must be considered. Increased levels of daily activity bring about decreases in liver fat stores and a single bout of exercise substantially decreases both de novo lipogenesis and plasma VLDL."
Exercise can prevent certain things happening, such as fatty liver, which you don't see, as well as repairing some things that have happened.
I saw a bit on Dara O'Briain's science show that demonstrated a measurable increase in {whatever it is that works your immune system} after 20 mins of exercise. I wish I could trace it as then I would know what {whatever it is that works your immune system} was. I think it was within the cells, maybe something to do with telomeres. This is what you get for flicking between channels and catching scraps. Anyhoo, the effect was marked and uncontestable, and most encouraging as it backed up my anecdotal experience of fewer, shorter colds etc.
