I'm also interested in your skepticism regarding the artofmanliness post, is it more to do with the claimed results or the recommendations? Certainly some incentive to trump up claims when generating revenue from ads on one's website.
Well, this is a monstrous topic and I've posted on it before, so some of the guys may be rolling their eyes as they read this.
Here are a few things to think about:
--Since the 70's they have been studying how to increase testosterone in dozens of countries with elite trainers, facilities and labs. Do you really think that all of these specialists missed the childlike solution given in the artofmanliness article? Why haven't we been hearing hundreds of reports and news feeds on men doubling their testosterone using these simple techniques that people have known about for years and years?
--If I remember right, the article pushed eating a lot of saturated fat. The studies and concepts that he is using comes from very old and small studies that I covered years ago here:http://www.peaktestosterone.com/twofs
These studies are well-known and you will find most explosive power athletes somewhat following these regimens or something similar.
--Will eating a lot of saturated fat actually boost testosterone? Well, it may for some men a little - it really depends on many (poorly understood) factors. But to say that doing these kinds of things will DOUBLE testosterone? Just to give you an idea: I have never known anyone on the forum who has doubled his testosterone from diet. The only person that I know that has doubled it through lifestyle underwent massive weight loss. Stop and think about that: is eating a bunch of saturated fat and lowering your fiber the equivalent of losing 70 pounds of body fat??
--Furthermore, there is a reason that this will not boost testosterone at all in many men: protein. Those same studies showed that too much protein will lower testosterone.
An example of this is a study that they did of men they put on a Low Fat Diet. Now a Low Fat Diet is supposed to be the antithesis of the artofmanliness diet, right? Yet check out #2 here:http://www.peaktestosterone.com/Testosterone_Estrogen_Ratio
These men GREATLY improved their testosterone-to-estradiol ratio and their testosterone remained the same. Again, their E2 dropped like a rock and their T stayed the same on a Low Fat Diet.
Now the guy going on a higher satured fat diet will likely blow out his arteries and erections for many reasons. In contrast, the Low Fat guys will be cleaning out their arteries and all at the same testosterone level that they maintained before.
--Now let's go back to one more point. Let's just that the artofmanliness article is partially right. Let's say if you go on the artofmanliness diet you'll end up with T of 650. And if you go on a Mediterranean Diet, you'll end up with T of 600. And if you go on a Low Fat Diet, you'll end up with T of 550. With the latter two, you are going to have greatly improved erectile function, increased nitric oxide and blood flow. In the case of #3, you will also likely actually clean out your arteries as well.
However, in the case of #1, the satured fat will decrease your blood flow and you will very likely accelerate arteriosclerosis. So you have traded a TON of blood flow and nitric oxide and arterial plaque for just a little bit of testosterone. Yes, testosterone is protective to a certain extent of NO and hardening of the arteries, but it will not be able to compensate for the artery-numbing effects of saturated fat.
--So is there a solution? Well, I love a Low Fat Diet, but realize most guys won't be able to handle that. So let me make a suggestion: go Mediterranean. It has pro-testosterone fat ratios per those earlier studies and monounsaturated fat are just as pro-T as saturated fat in those previous studies. And you get all the benes of the Mediterranean Diet:http://www.peaktestosterone.com/Med
So that's my two cents on the subject.
