Don’t you just hate that person on the treadmill? The one who looks like she was hewn from granite. Everything seems effortless for her. Run a mile and she looks like she just did ten. Instead of envy, you may need to turn to physiology. Selenoprotein P to be more precise. But we will get to that in a minute. First, let’s deal with the envy. The dictionary defines envy as painful or resentful awareness of an advantage enjoyed by another joined with a desire to possess the same advantage. What’s wrong with that? It might even be the perfect starting point. To conquering your own limits. You were only setting benchmarks. Great, that’s settled them. Back to the Selenoprotein P.
Your liver produces it. How much is the question? People who have Type II diabetes or a fatty liver seem to produce more than others. This causes insulin resistance and higher blood sugar. Turns out it has more lofty goals. That of reducing the impact of all that exercise you do. Really. This is why a run is not a run it is an “it depends.”
Not everyone responds equally to the same level of exercise. Especially those already pre-disposed to obesity and elevated blood sugar. A study was conducted on mice and later replicated on a small cohort of women. The group with elevated levels showed a reduced capacity to exercise over a thirty day period. Those that were deficient in the S. p showed a marked reduction in blood glucose and improved endurance. Over time this impacts how exercise affects you. But then you already knew this. It was never your fault.
The pharmaceutical industry searches for a clinical solution. In the interim presumably, you are well on the road to clean eating. It reduces blood sugar you know. The very same thing that caused you to be resistant nay envious in the first place.
