Nice article. I’m convinced that Boron, is an essential nutrient(and here in the states we have one of the lowest intakes of it), They’ve found so many ways that its beneficial(hormone, bone, joint….) for health) and almost no negative effects until absurd amounts are given. Boric acid is used in automotive oil as a colloid. It has the unusual property that the higher the pressure the more it lubricates. I think it may do the same in humans(it is concentrated in joint fluid). I had shoulder joint pain that prevented me from benching-3 days of 30mg/day boron eliminated it. Also note that boron is highly concentrated in the heart and testes.
Several studies concluded that diets low in fat (under 15% of total calories) significantly decreased testosterone levels while diets higher in fat (above 30% of total calories) increased serum testosterone levels. Rather than continuing with this discussion I will provide a link to an article which covers the subject quite nicely. To simplify everything that I have said, it seems that one should not lower fat below 15% of daily calories unless they would like to face extreme testosterone deficiencies. Likewise, one should not increase fat to say 40% in order to increase testosterone. Although fat increases testosterone to a degree, it is important to remember that testosterone is only a small piece of the larger puzzle. There are many other hormones and factors involved in building muscle other than just testosterone. By increasing fat to extremely high levels, there will be less “space” for carbohydrates and protein, both of which are very important for aforementioned reasons.
