Fasting and Testosterone levels
« on: June 28, 2013, 04:57:27 pm »
I wonder how many of us on the board ate breakfast before we had our bloodwork performed. According to this source, it may possibly give you readings 30% lower than actual. That could be a huge difference in diagnosing.

Okay, that is interesting.  There are a number of meals that have been found to lower testosterone so this doesn't surprise me one bit.  One of them, of course, is a high glycemic meal:

I've got some other examples and am going to work on a page soon.  Great reference Quincy.

Here's the original study for those interested:

If you are on medications or have a medical condition, always check with your doctor first before making any lifestyle changes or taking new supplements.  And low testosterone is a medical condition.
