Ketone bodies testicular toxicity and testosterone

Answered on August 19, 2014

Does ketosis adversely(ie. decrease) free testosterone levels in the circulation? I stumbled upon a blurb from 'heretical health' re: this causal chain and am curious to know if anyone else knows anything else? toxic testes sounds pretty 'heretical' in the weird-scientific sense.

Thanks Doc. Would you recommend keeping weight-training sessions to under 1 hour with two-per-day sessions(the first done in a fasted state upon waking) spaced by a 10-12 hour interval, one AM one PM? Also: is there a significant relationship between fast walking and cortisol(I include a 30 minute session daily)?

high cortisol causes lower T.....due to pregnenlone steal.

I am attempting to improve neuro-muscular connectivity in muscles and exercise technique so that I can perform oly/powerlifting at an amateurish level. Mainly, I am teaching myself technique and getting the old adrenaline rush simultaneously. Only starchy carbs PWO(see "diet and exercise routines, routines.."--my post with my diet/exercise routine that not many have checked out yet).

2-a-day workouts? What is your goal? No doubt that would be leaving you fatigued, and probably drive up cortisol, since you are stressing your body with a lot of physical activity. If you want to gain lean mass, you'll have to do some "carb-cycling", where you basically deplete your muscle glycogen over the course of training, and then refeed carbs on a certain week. I sued to do one every Saturday, and it worked alright. I just found and article that stated that there was no change in testosterone levels after 8 weeks of low carb (8%). http://carlcam.co.kr/2006/ECS/sub05/pdf/9_10-10.pdf

Thanks for the links, I'll investigate. Would you know anything re:weight-training volume and cortisol? I have ben doing 2-a-day workouts and this is leaving me fairly fatigued, maybe less 'drive'/positive aggression? Maybe the carbs need a boost... I have increased them but still fatigue remains, plus a little euphoria.

From personal experience, keto shouldn't decrease free testosterone. This site talks about the possible competition between ketone bodies and testosterone for reabsorption in the kidneys, leading to more testosterone being lost in the urine than normal. Make sure you're getting plenty of sat fats and cholesterol rich foods, and you shouldn't have any problems with testosterone production.

Also, see this thread.
