Vitamin D

This might be the range most of us should expect to be in at an intake of 10,000 IU/d. This is the equivalent to the body’s own natural production through sun exposure.

There are other factors that may affect levels. For example, being overweight tends to reduce them. Excess cortisol production, from stress, may also reduce them.

…and some days this turns into a bit of a medical blog.

This is mostly a blog post for me, so the next time I search for Vitamin D I can find this article. When Vitamin D supplementation comes up, and I mention that I take 10,000 IU daily… people ask why? …and I cannot remember why. This article from 2010 is why; 10,000 IU is about how much vitamin D my body would make if I lived somewhere sunny and I was a life guard.

Growth hormone may rise 300 percent with exercise

(Part 3 of 3 in series, Ned Kock's "Health Correlator")

Growth hormone stays flat for about 40 minutes, after which it goes up steeply. At around the 90-minute mark, it reaches a level that is quite high; 300 percent higher than it was prior to the exercise session. Natural elevation of circulating growth hormone through intense exercise, intermittent fasting, and restful sleep, leads to a number of health benefits. It helps burn abdominal fat, often hours after the exercise session, and helps builds muscle (in conjunction with other hormones, such as testosterone). It appears to increase insulin sensitivity in the long run.

Muscle loss during short-term fasting

(Part 2 of 3 in series, Ned Kock's "Health Correlator")

When the body is running short on glycogen, it becomes increasingly reliant on fat as a source of energy, sparing muscle tissue. That is, it burns fat, often in the form of ketone bodies, which are byproducts of fat metabolism. This state is known as ketosis. There is evidence that ketosis is a more efficient state from a metabolic perspective (Taubes, 2007, provides a good summary), which may be why many people feel an increase in energy when they fast.
