Low testosterone (T) symptoms may include low sex drive, erectile dysfunction, fewer sexual thoughts, mood problems, fatigue, loss of muscle, poor concentration, sleep disturbances, and fewer morning erections. Low T is also associated with several chronic medical conditions, including obesity, diabetes, osteoporosis, depression, and cardiovascular disease.

Men who get treated for low T have a very positive experience. The changes in appearance and mental state can be very profound. Interestingly, these positive changes associated with T therapy, have been found to occur at different times. A study from the University of Koln in Germany analyzed the relationship of time following administration vs. the effects on sexual functioning and mood on forty subjects. Researchers found sexual thoughts and fantasies occurred within weeks of initiating T therapy. Total number of erections rose steadily and peaked at 9 weeks. Ejaculations per week steadily rose and plateaued over 12 weeks. Depression decreased gradually and leveled off at 6 weeks. Mental concentration improved within the first 3 weeks, but overall mood did not improve until weeks 6 – 9.

Exercise induced endogenous hormone levels have been studied extensively. Researchers have examined how the different components of training including sets, repetitions, load and rest intervals affect serum levels of hormones such as testosterone, growth hormone and cortisol. Many studies have demonstrated there is an acute increase in serum levels of anabolic hormones after intense resistance exercise.

To be more specific, high intensity exercise coupled with short rest intervals that is performed with large muscle groups are associated with large rises in these hormones when compared to other training methods. Conversely, training small muscle groups like the biceps has been shown to have no effect on serum hormone levels. Because of the findings in many studies, training programs have been constructed to maximize the post-exercise rise in these hormones based on the assertion that exercise-induced increases in hormones like testosterone and GH will enhance muscle size and strength. But, considering the fact that these increases in hormone levels are very small and of short duration, will they produce muscular gains.

A study from the Kinesiology Dept. of McMaster University in Canada found that exercise induced hormone levels had no effect on muscle size or strength after 15 weeks of resistance training.

There is evidence that a minimal basal level of testosterone is required to support strength and hypertrophy gains, which are otherwise attenuated. Therefore, the hormone-sensitive processes that underpin muscle anabolism at hypo- and supra-physiological hormone levels are not being activated appreciably by exercise-induced increases in hormone availability or at least do not result in any measurable enhancement of strength or hypertrophy.

Does fat make us Fat?

Everyday in the news is some information about the fat.

We all need it, we all eat it.

What are the facts?

Here’s a simple guide to fats, the good, the bad and the ugly.

First realize that fats are a necessary part of any diet. We need fats to make hormones, build and repair tissues, and for energy. Gram per gram, fat provides about more than twice the energy of carbohydrates (9 calories per gram vs 4 calories per gram for carbs). Fats also help us absorb certain vitamins and satiates our appetite more than carbs or protein.

But there really are good fats and bad fats and the Cliff notes version of this column is this — if a fat is solid or semi-solid at room temperature, you should avoid it.

Most dietary fats fall in to three categories: Saturated fats, polyunsaturated fats, and mono unsaturated fats.

In a past Q & A column I respond to some hilarious comments?made by a man defending vegetarians.? Here is one of his comments and my response.??

K:? And Vittoni!! for your obviously dumb comment on Asian looks see who all I found to be a vegans- Sir Isaac Newton, Albert Einstein, Leo Tolstoy, Madonna, Paul McCartney, Socrates, Pythagoras, Mahatma Ghandi, H.G. Wells, Ralph Waldo Emerson, Plato, Leonardo Da Vinci, William Shakespeare, Buddha, Voltaire, Charles Darwin to name but a few.

BE:? I would love to see the proof that these people are all vegans, or even vegetarians. Do you really think Buddha got to be such a fat ass from vegetables? Although, maybe he went against the grain of Asian culture and ate large quantities of soy. This would have ensured his obesity, because of the detrimental effects it has on the thyroid. And by the way, Madonna has eaten plenty of meat, and has had her share of protein…if you know what I mean.
