Shelton and Rajfer (2012) noted that androgen deficiency in aging men is common, and the potential sequelae are numerous. In addition to low libido, erectile dysfunction, decreased bone density, depressed mood, and decline in cognition, studies suggest strong correlations between low testosterone, obesity, and the metabolic syndrome. Because causation and its directionality remain uncertain, the functional and cardiovascular risks associated with androgen deficiency have led to intense investigation of testosterone replacement therapy in older men. Although promising, evidence for definitive benefit or detriment is not conclusive, and treatment of LOH is complicated.
I’ve changed my sleeping habits lately also. Before I was going to be around 2am and getting up around 7am, terrible I know. The past week or so, I’ve adjusted that a lot. I’m going to bed around 10pm, and trying to get up around 5am. This is when I plan to get my workout in. Get up at 5, head to the gym, workout, hit the showers, and head on into work. I noticed another article you wrote about not eating before you work out. Do you feel you have plenty of energy for your workout when you do that? I’m one who can’t eat when I wake up, so I will probably be working out on an empty stomach also. It makes me nauseous if I don’t wait a couple hours to eat. At the same time, I don’t want to fizzle out during the workout, or miss out on any gains.
