I've read numerous health articles on the benefits of Intermittent Fasting. It is supposed to give your body time to remove toxins. It gives your digestion system a much needed break, and most importantly if done for a period of 24 hours, it helps your body's hormones balance out. Thus increasing HGH in the pituitary gland. Have you guys out there notice higher testosterone symptoms such as, more agressiveness, better mood and higher sex drive?
Take a look at this study: http://jcem.endojournals.org/content/83/6/1967.long
"In summary, fasting in young but not older men reduces 24-h LH secretory burst frequency and mass and (24-h pooled) serum free testosterone concentrations. Fasting in young but not older men enhances the quantifiable orderliness (lower ApEn) of LH release, and alters 24-h LH rhythmicity. Thus, we conclude that the metabolic stress of short-term fasting unmasks age-related dynamic differences in the pulsatile, 24-h rhythmic, and orderly release of LH."
This article states that fasting reduces free testosterone in young men. I hope there are someone her who have a higher knowledge of the endocrine system than I do that can simplify the mechanisms described in the article.
I personally don't notice any noticeable testosterone traits from IF. I'm on ZMA, and I attribute a lot of my aggressiveness to that supplementation.
Try an IF protocol for a week and see how you feel. Everyone is different, so give it a shot. I'd recommend staying around 16 hours, not 24.
I'm on my 4th week of IF. I do notice an increase of assertiveness that might correlate to a boost in test. But I also have a few other exciting things going on in my life as well. Hard to conclude but like TnQ posted I'm sure IF lowers Test. Pretty sure it's on the LeanGains site & Anthony Copolo's site (sorry nolinks).
