Congrats on this new book! I can’t wait and am VERY interested in it – especially as a hardcore dancer (daily training) 53 year old perimenopausal woman. I’ve experimented with what I understood Ketogenic diet to be and found the effort not difficult during my ‘2-month rest periodization’ window but am confused about how to remain Keto and even Primal now that I’m back into intense training window. I seem to need more carbs…Will continue with Primal until book comes out and hope for clarity then!
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.
