Comment of the week
“Re: Sunday with Sisson – One remarkable thing about life is that it appears to counteract the increase in entropy / disturbance that physics normally associates with increases in heat and the passage of time. Exercise and learning make our bodies and brains more organized, and the efficiency with which they convert heat into work improves. This does not violate the second law of thermodynamics as the total entropy of the universe is still increasing. The increase in entropy of the environment outweighs the decrease in entropy associated with a more orderly state of brain or muscle structure and function. When we move, the entropy of the surroundings of the muscles and nerves increases, so that no ordered structures such as fasciae adhesions develop.
But that only happens when several systems interact in a complex manner – the logic does not hold if a joint lacks cartilage or synovial fluid, or if our diet is lacking magnesium or something like that. The conversion of heat (calories) into internal order also has its limits, because too much exercise degrades our body. Things like life and optimal performance are only possible with a finite range of exercise intensity, specific movement patterns, and the right balance of dozens of food inputs. Bed rest and chronic cardio are both suboptimal; too much or too little movement in a joint is suboptimal; too much or too little of an essential nutrient is suboptimal.
I think consciousness evolved to recognize deviations from optimality in these complex internal states while adjusting many internal components through comparatively simple behaviors – just move around so that it doesn’t cause too much pain and eat those Foods that appetite dictates (but obviously. Modern food chemistry, desk jobs, etc. mess that up). We all feel that we crave certain foods when we lack a certain nutrient, and this unconsciously controls our eating behavior. Primitive people like to avoid processed foods because they are high in calories and low in nutrients, which makes us crave more food to get the nutrients we need, leading to overeating and weight gain. Scientifically this is speculation, but there is some new and noteworthy science here. Not sure if I can post links, but a search for ‘Drosophila microbiome-gut-brain axis response to an amino acid deficit’ should reveal a new paper showing the causal relationship between a specific nutritional deficiency and an appetite indicates a specific type of food. Sure, it is Drosophila, but presumably the mechanism is similar in humans and, to my knowledge, it is the first such evidence of its kind in a species. So yeah, you could think of exercise as the key to anything in life because without it you’d be dead and things break if you do them too hard, but like diet and social interaction, it’s just one key on the chain.
-Nice comment from the investigator.
